Transfer switches are essential to backup generators.
Transfer switches are designed to supply power to electrical circuits from multiple power sources. They prevent the risks of electrocution and are required for any backup generator. There are three types of transfer switches: manual, automatic and combination.
Manual
Manual transfer switches (MTS) are the least expensive and least complicated. They require someone start and stop the generator as well physically operate the MTS. This transfer switch comes in a variety of sizes and configurations. Manual transfer switches are used by portable and stationary generators.
Automatic
Automatic transfer switches are best in times over power outages It is capable of monitoring the power supplies and automatically switching from utility supply to the generator power source. When power is restored, it automatically shuts the generator down and transfers back to the normal power source. Maintenance schedules can be predetermined to ensure the backup generator works when needed. It has various control and alarm features.
Combination
Combination transfer switches function as either an automatic transfer switch or a manual transfer switch, depending mode of operation. This allows for flexibility in use.

Activate the A380 "Self-Timer" mode to capture self-portraits properly.
The Sony DSLR-A380 single lens reflex digital camera features a sliding monitor, which pivots away from the camera back and allows you to view the composition as you look down. After the batteries are installed, the memory card is inserted and the lens is attached, you might have questions about operate the A380. The basics include image capture, use of the zoom function, scene mode selection, flash mode selection, image review and image deletion.
Instructions
1. Twist the mode dial on the top-left side of the A380 to "Auto" and twist the monitor on the back of the camera to a comfortable viewing angle. Point the camera at the subject and frame her within the monitor or the viewfinder, which is the small window on the camera back.
2. Twist the "Zoom" ring, which encircles the lens, if the lens is a zoom lens, to zoom into or away from the subject. Twist the ring clockwise to zoom into the subject or counterclockwise to zoom away from the subject.
3. Push the shutter button on the top-right side of the A380 halfway down to achieve automatic focus and setting adjustment. The focus indicator button lights up inside the viewfinder or on the monitor to let you know that the subject is in focus and the picture is ready to be taken. Depress the shutter button completely to take the picture.
4. Twist the mode dial to the appropriate scene mode to capture specific scenes. For instance, if you wish to capture a portrait, twist the mode dial to "Portrait" or the setting marked with a face to blur out the background and soften skin tones. Shoot full ranges of scenery with sharp focus and dense colors by setting the mode dial to "Landscape." Twist the mode dial to "Macro" to capture close-ups of objects, such as insects, flowers or coins.
5. Press the navigation button on the A380 back to the right toward the icon marked with a lightning bolt to cycle through the flash settings, until you highlight the desired flash setting. Highlight "Flash Off" to turn the flash completely off regardless of the lighting situation. Highlight "Fill-Flash" to command the flash to fire with each capture regardless of the lighting situation. Highlight "Autoflash" to allow the camera to decide when the flash fires based on light readings.
6. Press the "Play" button or the button marked with a triangle on the back of the A380 to activate image playback. Press the navigation button to the left or right to travel backward or forward through the image library.

VCRs can be hooked up to a digital TV the same way they can be hooked up to an ordinary TV. The only downside is that they can't send a signal with the same level of clarity that a modern DVR or DVD player can. Most VCRs were made before the advent of digital broadcasting, and the cables they use simply can't carry the large amount of information entailed in a high-definition broadcast. The good news is that you can still get a solid signal out of your VCR: We watched those signals for decades, after all, and didn't seem to complain much then.
Instructions
1. Find the RCA cable jacks in the back of your VCR. There should be at least two sets: one labeled "In" or "In From Antenna" and one labeled "Out" or "Out to TV." RCA cables consist of three separate wires. The yellow one conveys the video image, the red one conveys the right-hand audio signal and the white one conveys the left-hand audio signal . The jacks in the VCR are small and round and will be color coded to correspond to the three RCA cables.
2. Locate a similar set of cable jacks in the back of your digital TV. They may be labeled "In" or "In From Antenna," but they look just like the ones in the VCR: one yellow, one white and one red. High-end TVs may have multiple sets of RCA cable jacks. That's fine. Just be sure you note which set you intend to use, so you can tune the TV to them when you're done.
3. Connect the "Out" jacks in the VCR to the "In" jacks in the digital TV with a set of RCA cables. Match each cable up to its corresponding color and make sure the connections are secure.
4. Connect the antenna or cable box to the "In" or "In From Antenna" jack on the VCR. With a cable box, you should be able to do this with another set of RCA jacks. If you don't have cable, use the coaxial cable jack on the VCR--it has a white plastic center with a pinhole in the middle--and plug the antenna directly into it. (Some older cable boxes may require the use of coaxial cable as well.)
5. Turn on the digital TV and find the "Input" or "Set-Up" button on the remote. Press it and set the TV to receive signals from the set of jacks connected to the VCR. You should now be able to watch and record shows on the VCR normally.

Time lapse video recorders are the old age recorders that allowed the compression of hours of video recording on VHS tapes for future viewing. They are the pioneers of the "time shifting"' concept that has now been modified with enhanced features in a DVR. Let's compare the two in the following steps.
Instructions
1. Understand the formats followed by both. DVRs follow a digital format, resulting in more than 480 horizontal lines in color, whereas the best time lapse recorders offer 300 lines in color. This means the resolution with a DVR is superior to that of a time lapse recorder.
2. Understand the difference in reproduction. DVRs are digital and therefore provide better picture clarity with little input, whereas time lapse requires a lot of information to reproduce an image.
3. Compare ease of storage. Storage of DVR data is as easy as it gets. You can store your information on a hard drive or simply upload it to a chosen server on the Internet. This makes it easier to retrace your data in the future. Time lapse recorders store information on tapes, which means that the more information you have, the more tapes you'll have to deal with. Storing tapes securely is a huge and inconvenient task.
4. Study the storage risks of both. DVR data is always at risk for technical failures like system crashes and permanent loss of data. On the other hand, tapes are susceptible to fading and damage in the long run and require careful maintenance.
5. Compare the surveillance facilities of both. Network DVR models support camera surveillance via Internet, making it easy for you to monitor the happenings in your establishment from home, another city or even another country. Such a facility cannot be made possible by a time lapse recorder.
6. Learn more about the potential of both. DVRs are coming out with newer business-specific innovations like Point Of Sale, which not only monitors the customers but also monitors the cashier, negating any chance of manipulation. On the other hand, time lapse recorders are widely considered to be a passing technology and are expected to give way to DVRs completely in the future.

Graphic equalizers are an integral part of any stereo system. The equalizer allows you to boost or cut specific frequencies to tailor sound to room acoustics. It also allows you to compensate for speakers and cabinets that boost or attenuate certain frequencies and throw off the tonal balance of your music.
Instructions
1. Purchase two RCA cables. Unless your receiver and equalizer are far apart, use "patch style" cables. These are generally one foot or less in length.
2. Locate the tape out jacks on your receiver. This is typically located on the back of the receiver. Plug in one patch cord to the receivers tape out jacks and insert the other end into the audio inputs of the graphic equalizer.
3. Locate the audio outputs of the graphic equalizer. They are generally found on the back of the equalizer right next to the audio inputs. Plug the second patch cord into the audio outputs of the equalizer and into the tape inputs of the stereo receiver.
4. Connect the equalizer to a wall outlet and power on the system. Use the sliders or knobs on the front of the equalizer to make audio adjustments as needed.

A pressure cooker is a pot with a tight-fitting lid that can be locked to form an airtight seal. As the liquid inside the pot boils, it produces steam. The trapped steam produces pressure, which raises the temperature inside the pot, forcing the water to boil at a higher temperature. This allows food inside the pot to cook at higher temperatures than in an oven or on the stove. A pressure cooker can have several advantages over other cooking methods.
Pressure Cooker Basics
Pressure cookers are usually made from aluminum or stainless steel and may be coated with a nonstick material. Cookers generally come in 4, 6 or 8 qt. sizes. Pressure cookers need to be large so that there is room for the steam to expand inside the cooker. While all pressure cookers have pressure regulator valves to vent excess steam, some cookers are built to maintain a constant pressure while others allow you to adjust the pressure in the cooker.
How it Works
A pressure cooker works by using steam to build pressure within the pot. As air pressure rises, water boils at higher temperatures. Under 15 pounds of pressure per square inch (psi), water will boil at 257 degrees instead of 212 degrees Fahrenheit. This means that foods inside the cooker can reach temperatures of 257 degrees Fahrenheit without burning or drying out. Foods cook more quickly, but do not lose any moisture or nutrients to the air, so they retain all of their moisture and nutritive value.
Benefits
Because foods made in a pressure cooker are cooked in a moist environment, you do not need to use much oil or other fats to prepare them. The steam locks in flavor, so you can also use less salt, and vegetables retain their color when cooked this way. These benefits make a pressure cooker especially useful for preparing foods for those on a low-salt, low-fat diet. Pressure cookers also allow you to cook foods faster, meaning that they use less energy than conventional cooking methods and save you time in the kitchen. Stews can be cooked in 15 minutes while a medium-rare pot roast may take as little as 30 minutes.
Drawbacks
Because food cooks very quickly in a pressure cooker, it can be easy to overcook your dish. Additionally, flavors may not be as deep as when foods are cooked more slowly, and you may need to brown meat, onions and other foods before putting them in the cooker in order to enhance the flavor. You will also need to adjust any favorite recipes to work in a pressure cooker, such as using smaller amounts of flavorings and adding ingredients at different times; this may take some trial and error to get right. You also need to be very careful when opening a pressure cooker after cooking with it as any steam remaining in the cooker can scald you.

Everyone wants to protect their family from intruders. When we think of intruders, we usually think about burglars and other criminals that might break into our homes by smashing a window or picking a lock. But there's another way intruders can get into your home and harm your family--the Internet. Computers provide a gateway for predators into your home, and it's just as important to monitor that gateway as it is to lock your windows and doors.
Instructions
1. Check the keystroke logger program you choose for compatibility with your operating system before buying it. Not all programs work with Windows, Mac, and Linux.
2. Find out how many licenses of the software you are buying. Some programs require you to have a separate license for each computer you install it on, and you want to be able to monitor all the computers in your home or office.
3. Understand what a keystroke logger does. These programs provide hidden computer monitoring of every stroke the other users of your computer type. They can be used to protect children from communicating with predators, monitor visits to illicit websites or catch a cheating spouse.
4. Shop for keystroke logger software online or at a computer supply store. Compare the features on the various programs. Your keystroke logger should be able to operate secretly, monitor emails, record Internet connections and websites visited, record chats and instant messages, log times of computer usage for each user name, record all passwords, take periodic snapshots of the screen and have encryption capability to prevent tampering.
5. Install the program on the computers in your home when you are alone. The clandestine nature of the program is what makes it effective. If your children know they are being monitored, the could engage in inappropriate online behavior on a friend's computer or elsewhere.
6. Install the program according to manufacturer's instructions. Most keystroke loggers are easy to install and can be running in minutes.
7. Install keystroke logger software on office computers to gauge productivity and monitor improper Internet usage.
8. Combine keystroke logger software with blocking software and parental controls to monitor computer usage even more.
9. Commit to regularly checking the logs created by your program to track any inappropriate behavior. The keystroke logger creates the logs, but you have to check them for them to be effective.

Modern automobiles often contain portable DVD players and audio systems. A portable automotive DVD player uses a 12V DC outlet as its power source. To use an automotive DVD player inside a home, the DVD player would need a 12V power source. A wall outlet, when used in conjunction with a DC adapter plug, can supply electrical power for the DVD player.
Instructions
1. Adapter tips are clearly marked as to which wire is positive.
Snip the adapter tip, and strip 1/2 inch of insulation from the wire ends. Pull apart the adapter wire ends until there is a 6-inch separation between the wire ends.
2. Slip one of the alligator clips over the positive adapter wire, and solder the clip to the wire. Slip the remaining clip over the negative adapter wire, and solder the clip to the wire.
3. Attach the positive alligator clip to the "Power" wire on the DVD player. Attach the negative alligator clip to the "Ground" wire on the DVD player. Plug the adapter into a wall outlet. Turn on the DVD player.
Printing pictures used to be somewhat of a hassle. Today, you can quickly and inexpensively print your own colored photos right at home on your own computer. All you need is a printer, colored ink and photo paper to print out high quality pictures. What's even better, you can crop, adjust, erase red eye, hide blemishes and enlarge your pictures by yourself right at home. Insert your camera's memory card into your computer (or hook up your camera to the computer through a USB cord), and you're all ready to print your photos.
Instructions
1. Ensure that your inkjet printer-or dye-sublimation printer-is properly hooked up to your computer. Inkjet and dye-sublimation printers work best to print out high-quality photos. The most common printers today are inkjets.
2. Open the printer's cover. Remove the black-and-white ink cartridge from the printer, if necessary. Insert the colored ink cartridge into the cartridge slot.
3. Remove any old printer paper from the paper tray. Properly insert the photo paper into the paper tray. HP, Canon, Kodak and Epson all make high-quality photo printer paper. Your printer may need you to place the photo paper into the tray with the photo side facing down.
4. Open Windows Photo Gallery. Click on the photos that you want to print from your computer.
5. Choose the print size of the picture on the right side of the screen. The standard size of a photo is 4 inches wide by 6 inches long (4-by-6).
6. Select "Print" from the toolbar. A separate dialog box will open; in that box, select "Print" again.

Boston Acoustic's lineup of Pro Series car speakers are a high-quality aftermarket alternative to the stock speakers put into cars by the manufacturers. Since they can handle high amounts of power, they're suitable for use with an aftermarket external amplifier. To achieve the best performance, it's necessary to connect the speakers properly to the amplifier.
Instructions
1. Identify the parts of your Pro Series speakers. In each pair, you'll find two woofers (the larger speakers), two tweeters (smaller speakers), and a set of crossovers (rectangular boxes with wiring set screws). Split them up into two groups, each group having a woofer, tweeter, and crossover.
2. Connect the wiring leads from the tweeter to the crossover. First, strip about 3/8 inch of insulation from the tweeter's speaker leads, and then connect the wire marked "+" to the set screw marked " Tweeter +". Tighten the set screw. Repeat the process with the "-" wire, connecting to the "Tweeter - " set screw. Do this for both tweeters, connecting one to each crossover.
3. Connect the woofer to the crossover. With a piece of speaker wire, connect the "+" terminal of the woofer to the set screw marked "Woofer +" on the crossover. Repeat with the woofer's "-" terminal, connecting it to the set screw marked "Woofer -". Do this for both woofers, connecting one to each crossover.
4. Connect the crossover to the amplifier. Strip 3/8 inch of insulation off of each end of a length of speaker wire. Connect the set screw terminal marked "+" on the crossover to the terminal marked "Output +" on the amplifier. Repeat for the "-" terminals. Do this for both crossovers, connecting one to each of the amplifiers outputs.

Shadows in indoor photography are usually caused by your flash unit. Because the flash is so much brighter than ambient light, it acts as a point source and causes shadows. There are several ways to avoid shadows when shooting indoors, including diffusers, hoods, bounce flash, natural lighting and off-camera flash.
Avoid Flash
You can avoid using your flash unit if you position your subjects in natural light near a window, door or skylight. If you are using natural light indoors, you may need to shoot at relatively low shutter speeds. If you are using a 105mm equivalent or greater portrait lens, camera shake can be an issue at lower shutter speeds; use a tripod to compensate.
Bounce Flash
A quick and easy fix to shadows caused by an on-camera flash is to point the flash up at a white ceiling, aiming for a spot halfway between you and your subject. The light from the flash bouncing off the ceiling will be more diffuse than direct light from the flash and less prone to causing harsh shadows.
Diffuser Over Front of Flash Unit
Another quick and easy method to soften shadows from flash photography is to place a diffuser over the flash unit. You can buy diffusers, but in a pinch any thin white cloth such as cheese cloth or even a very worn white T-shirt will work. Flesh-colored women's stockings will diffuse the light from the flash and add a slightly warm tone.
Flash Diffusion Hood
Another possibility is to buy or make a simple flash diffusion hood that you attach to the top of your flash unit. A diffusion hood is essentially a piece of white plastic or cardboard placed at a 45-degree angle to the camera. When you point the flash up at the hood, the hood reflects the light of the flash forward at your subject. The light is sufficiently scattered by being bounced off the hood to reduce the amount of shadows caused. Commercially sold diffuser hoods use light-diffusing materials, but in an emergency you can fashion a basic functional diffuser hood with a few pieces of white cardboard and duct tape.
Off-Camera Flash
If you have a separate rather than a built-in flash unit, you can move it off camera to avoid unpleasant shadows. Imagine a quarter piece of pie, with one edge running from the camera to the subject and the other edge perpendicular to that line. Place the flash at a 45-degree angle, or what would be the middle of the pie crust, and raise it a few feet higher than your subject's head. This is the classic position for portrait lighting and is very flattering.
Professional Options
Professionals use multiple flash units and carefully positioned reflectors and diffusers to compensate for shadows. Professional photography stores carry a wide range of lighting equipment and may also offer seminars on use it.

The Palm Treo 700P cell phone, like most Palms, has a wide array of accessories. One of these, the External Antenna Adapter, is used to connect your Treo 700P to an external cellular antenna for increased reception. When using the External Antenna Adapter, be aware of some common problems that can arise.
No Connection
When your Treo 700P is plugged in using the External Antenna Adapter, it might not make a connection. If this is the case, verify that both ends of the adapter are securely plugged in. Remove each end of the adapter and firmly slide them back in until a tight connection has been made. If no connection is being made to the external antenna, the problem might lie in the jacks themselves. Try a different external antenna. If this doesn't work, your Treo 700P is defective and needs to be serviced.
Defective cable
If you have problems with your External Antenna Adapter, verify that your cable is not damaged. Check the metal connectors at either end of the cable for signs of damage, such as chipping or bent metal. Make sure the cord has no kinks and is fully extended when in use. Check the cord for signs of damage, such as rips, punctures or bites from a pet.
Compatability
Make sure the External Antenna Adapter you purchased is compatible with your Treo 700P. There are many different kinds of adapters for different Treo phones. Check the packaging to ensure your Treo 700P model is listed and. Bring your phone to the store and ask the employee if you can try the adapter out before you buy it.

FireWire, also called IEEE 1394 and i.Link, is a type of high-speed serial bus connection that allows electronic devices to communicate with one another. Its cords come in a variety of lengths and connector types, the need for which depends on the device into which they are being connected.
Function
FireWire cords, or cables, are most commonly used with electronic devices like video cameras, which need to transfer high-quality video and audio data quickly. According to the 1394 Trade Association, devices that use FireWire cords can access some data at up to four times the speed of USB 2.0.
Types of Connectors
A 4-pin FireWire cable.
FireWire cords end in three different possible connectors: 4-pin, 6-pin and 9-pin. 4-pin and 6-pin cables are commonly used with FireWire 400 (IEEE 1394a) devices, which transfer data at speeds up to 400 MB per second. 9-pin cables are used with FireWire 800 (IEEE 1394b) devices, which transfer data at speeds up to 800 MB per second.
Significance
Unlike USB, with the use of repeaters a FireWire connection can be extended up to 100 meters in length without a loss of speed. FireWire cables can also be "hot plugged," which means they can be plugged and unplugged without powering off your external device. FireWire cables also do not need any special drivers to work with your computer.

Choose photo mat colors that complement your framed photographs.
Mats are a visually pleasing way to enhance certain aspects within photographs and they can make your images stand out in the center area of surrounding frames. In addition to aesthetic functions, they also protect and preserve photographs by adding air pockets and reducing moisture over time.
Choosing the Right Shade
Use single mats in light, neutral shades with photographs because these mats easily complement a variety of frame colors and styles as well as framed images. Use darker mats if you want to pull distinct colors out of photographs that the mats will surround.
Two Mats
Use two mats to add dimension and matching hues to a framed photograph. By using a neutral-colored outer mat with a darker-colored inner mat that matches something within the photograph, you can achieve an attractive, complementary look.
Putting it Together
Pull all of the elements together by using acid-free tape to attach the print to the mat. Use a piece of tape to adhere the top portion of the photograph to the mat. Don't tape the top and bottom ends (or all sides) of the photograph to the mat because your photograph should be allowed to breathe while it sits in a frame for an extended period of time. Use acid-free foam core or manila board to enclose mats on the backside of a frame.

Listen to the audio as radio interference is minimized, if not removed altogether, through the transmission of the audio via Bluetooth technology.
Installing a power amplifier for your home audio system is a great way of getting some extra juice to drive your speakers. In a component-based system, it's also one of the necessary pieces of equipment you'll need to hook up. The power amp is hooked up between the preamp and speakers. Here's get it done.
Instructions
1. Connect the preamplifer or receiver to the power amp. It will be a line level connection and specific cables needed vary by model. You will either use balanced connectors (XLR) or RCA connectors. Run a cable for each speaker that you plan to power with the amplifier.
2. Strip the ends of your speaker cable and insert two ends from one side of the cable into the power amplifier's speaker outputs.
3. Connect the other ends of your speaker cable to the appropriate speaker. Be sure to match the polarities properly (positive to positive and negative to negative).
4. Repeat Steps 2 and 3 for each speaker that will be powered by the amp.
5. Plug the amp into the electrical outlet. Your power amp is now hooked up and ready to play.

A FireWire computer connection is used for transferring large files.
The IEE 1394 port, known as FireWire, is a high-speed transport port created for use with large audio and video files. Capable of transfer rates of up to 400 Mbps, the port quickly moves these large files between devices for editing or presentation. With a computer that has the Windows operating system, use of the port is simple, using Window's plug-and-play feature to recognize devices as they're plugged into the port and give you a listing of applications common to that device. In addition, you can extend the port's use in creating a direct cabled network between two computers.
Instructions
1. Locate the IEEE 1394 port on your computer. You can look at the FireWire cable ends to see which port will fit the shape of the cable connection. Plug the cable into your device, turn on your computer and allow it to boot to the desktop.
2. Plug the IEEE 1394 plug into your computer and wait as the operating system recognizes your device. The wait may be a minute or two depending on the device type. Once recognized, Windows will inform you of the detection of your device, and open a dialog box presenting you with options related to the use of that particular device.
3. Choose the option related to your desired device. Options consist primarily of applications related to the device. For example, you will see options for Windows Movie Maker after plugging in a video camera, or Windows Explorer for an external hard drive. Select the option by clicking on your choice to start the application and make use of your connected device.
4. Use the IEEE 1394 connection as a single-session networking device by plugging the cable between two computers possessing IEEE 1394 ports. Plug in the cable and wait for Windows to create a network connection. Open Windows explorer and type "\\machine_name" into address box at the top of the explorer window, substituting the linked computer's machine name for "machine_name." This will give you access to shared components and files on the second computer.

When deleting images is as easy as the flick of a button, most camera users will find themselves in the unenviable position of having just deleted pictures they actually want to save. While their first reaction may be panic, many images can be retrieved with a small amount of time and modest expense. Getting the photos back is not challenging and should be done, if possible, soon after the users realize the images were deleted.
Instructions
1. Connect your digital camera to your computer using the USB cable. Wait for the camera to show up as connected to your computer.
2. Download a photo-recovery program. Ask Dave Taylor recommends CameraSalvage for Mac users, which is $50 in 2010 but which users can try free in demo mode. PC users can try CardRecovery, Art Plus Digital Photo Recovery or other similar programs.
3. Open the newly downloaded photo-recovery program. Mac users can find it in Applications and PC users can access it through the Start menu.
4. Select the drive for your photo-recovery program to scan your memory card. The memory card will be listed under the manufacturer, so you can easily identify it. Now press "Start" and wait while the photo-recovery program scans the memory card.
5. Wait for the program to scan the card. This will take a while if you had lots of images on the memory card.
6. View images from your memory card as thumbnails.
7. Check the boxes next to tiles you wish to save and select the "OK" or "Salvage" button (the name varies depending on program). Alternately, hold down the Ctrl key (PC users) or the Command button (Mac users) and highlight the file names with your mouse. Then click the "Salvage" button.
8. Wait while the photo-recovery software scans the deleted images back onto your computer.
9. Close the program when you finish and safely disconnect the camera from your computer.

InFocus projectors are a line of projectors released by the InFocus Corporation. The projectors are compatible with both computers and DVD or VCR players. InFocus projectors are as easy to hook up as any other device in a home entertainment system. Once hooked up, projectors can be used in a home theater system.
Connect the Projector
InFocus projectors can connect to computers, DVD or VCR players. The connection is through the video and audio ports on the projector and the device. For computers, connect the cable to the external monitor port and plug the other end of the cable into the computer input port on the projector.
The DVD or VCR is hooked up through the audio/video output ports on the device. Plug the cord into the output port and connect the other end of the wires to the input ports on the back of the projector.
Once connected, the projector is ready to play images from the source device.
Running the Projector
Plug the power cord to the back of the projector and connect it to a working power outlet. The indicator light on the "Power" button will light up amber. Press the "Power" button to turn on the projector. The indicator will blink green while the lamp warms up. Once the light stays green, the lamp is warmed up and ready for use. Turn on the source device and navigate to the material you want the projector to display.
Adjusting the Projector
You may find the image projected by an InFocus projector needs adjustment for proper viewing. There are several steps users can take to properly adjust their projector. First, to adjust the height of the projection, press and hold the leg release button on the top of the projector. Raise or lower the projector until it is at the correct height.
If the picture from the projection is not square, press the "Keystone" buttons on the top of the projector near the back. The top "Keystone" button will adjust the top corners of the picture, while the bottom "Keystone" button will adjust the bottom corners.

When using a JVC video camera, you may encounter issues, including the camera not staying on,the camera failing to record information or the recorded data not uploading to a computer system. Regardless of the problem, a few troubleshooting tips can go a long way toward fixing it.
Instructions
1. Completely charge the battery on your JVC video camera. If the camera's battery is beginning to fail, the video camera is going to shut off unexpectedly.
2. Spray compressed air into the tape deck on the JVC video camera, if the camera uses tapes to record. When the deck becomes dirty the recorded content may have distortion, such as lines across the screen or even static. Distortion occurs when dust scratches the tape.
3. Insert a new tape or memory card into the camera. If the camera's storage device is full, you are going to receive an error message, stating you are unable to record any additional video.
4. Delete excess files from your computer system. If the current hard drive is full, you are unable to upload video to the computer. Making room on the computer's hard drive allows you to upload footage from the camera and delete the content from the video camera's drive.

When it comes to digital cameras--especially digital single-lens reflex (D-SLR) cameras--Canon and Nikon are often at the top of the list in terms of quality and reputation. In 2008, Nikon released the D60 as one of its mid-range D-SLR cameras. The same year, Canon released the XSi--a mid-range competitor to the D60.
Continuous Shooting
D-SLRs separate themselves from point-and-shoot cameras with their ability to shoot a lot of photos in a short amount of time. The D60 can shoot up to three frames per second, compared to the XSi's ability to shoot up to 3.5 frames per second. The XSi can continue that shooting burst for up to 53 JPG photos, whereas the D60 can continue its shooting burst for up to 100 consecutive JPGs.
LCD
The LCD screen on a D-SLR serves a number of functions: instant review of your photos, setting and reviewing camera settings and--in some instances--a live view function that allows you to use the LCD to shoot your photos rather than the viewfinder. The D60 has a 2.5-inch screen with 230,000 pixels and the XSi has a 3-inch screen also with 230,000 pixels. The XSi, however, has the live function and the D60 does not.
Megapixels
The more megapixels your camera has, the larger the photo you can print without affecting the quality of your photo. In its 2008 how-to guide on buying digital cameras, Target recommends using a camera with at least 6 megapixels for photos 8-by-10 inches or larger or smaller photos with fine details. Both the D60 and the XSi surpass this recommendation with 10.2 and 12.2 megapixels, respectively.
Size
Because of their advanced settings and features, D-SLRs are larger than point-and-shoot cameras. Nikon dubbed the D60 its "smallest Digital SLR ever," measuring in at 5 inches wide, 3.7 inches high, 2.5 inches deep and a weight of 16.1 ounces. The XSi is fairly comparable in size--5.1 inches wide, 3.8 inches high, 2.4 inches deep and a weight of 16.8 ounces.
Rechargeable Battery
D-SLRs are far more powerful than point-and-shoot cameras, and therefore use a lot more battery power. To keep you from having to run to the store all the time in search of new batteries, both the D60 and the XSi come equipped with a rechargeable lithium-ion battery pack. In mild temperatures, using little or no flash, the XSi's battery (the LP-E5) can take up to 600 photos between charges. Under those same conditions, the D60's battery (the EN-E19) can take up to 500 photos between charges.
Price as of 2009
Both the D60 and the XSi can be purchased with the only the camera or in a kit, which includes accessories and lenses. As of September 2009, a D60 kit--which includes the camera, accessory kit and an AF-S DX NIKKOR 18-55mm lens with vibration reduction--has an estimated price tag of $649.95. The Xsi kit, which includes the camera body, the accessory kit an EF-S 18-55mm lens with optical image stabilization, has an estimated price of $749.99. Both Canon and Nikon note on their websites that those prices are estimates and that the retailer you purchase your camera from determines the final selling price.
Developed by corporate telecommunications company Avaya, the Audix multimedia server is available exclusively to business users. With its voice-mail-to-email feature, users can listen to their phone messages on a computer and forward them to another email address. Your company's IT department or another professional typically sets up an Audix server.
Audix System
As a multimedia server, Audix can link a corporation's email and voice mail systems. A voice mail received on a corporate telephone can be sent via the Audix server to an email address also linked to the server. Each computer or phone doesn't contain the server; instead, the company grants specific users access to the same server. As an authorized user, you can open a voice mail and play it through your computer's speakers or headphones.
Application
To receive voice mails within an email client, your network must have the www.messenger application. Avaya Professional services must set up the application for all users, as the software lives on a separate server and communicates with the Audix server via a Web browser. To play your voice mails on your computer, you need a sound card, Internet Explorer or Netscape Navigator, and Avaya's Voice Player, which is a Web application that helps with playback. The system administrator at your company will provide a URL that allows access to the application.
Compatible Email Programs
Audix will work with many email programs commonly used for corporate communication, including Microsoft Outlook, Microsoft Exchange, Lotus Notes 4.6, Netscape Navigator, Eudora Pro and Eudora Light. While you can access your email from a mobile phone with a Web browser, you won't be able to play voice mails, because your phone's IP address isn't configured to the server.
Considerations
As of February 2012, Audix is a Windows-based program, so Mac users can't listen to voice mails via email, even if they have the required company-based email address. Also, you must have an active Internet connection to use the www.messenger server or the Avaya Voice Player.
A transformer is built from coiling wires around an iron core. The output wire is wrapped around the core as well, but the number of coils is reduced. By reducing the number of coils, the technician is able to significantly inhibit the flow of voltage coming off the output wire.
Types
The technician or builder will determine the type of transformer to build. There are liquid insulated and gas-cooled transformers to select from. Liquid-insulated transformers utilize conventional mineral oil, hydrocarbons or silicons as a cooling medium. The technician will build a liquid-insulated transformer for better overload capacity, especially if the coils need to be cooled quickly. The life span of a liquid-insulated transformer is higher than a dry transformer. However, the technician will build a shielding trough to prevent fluids from leaking (liquids mediums are more fire prone and might explode). If the transformer is built indoors (600 volts or less), then the technician or engineer will select a dry-insulation design for the transformer. Outdoor installations tend to be liquid-insulated transformers because of the higher-voltage capacity in liquid mediums.
Liquid insulation
Liquid-insulation transformers are made of enameled wire. Cellulose paper (made from sulfate wood mash) containing a di-electric liquid is placed inside of the liquid-insulation transformer. The coil arrangement (with iron core) is mounted in the liquid-containment tank, with leads connected. The liquid medium is funneled into the containment tank. Additional leads are added to the containment tank to provide an electric current to the coils (moisture is removed). Heated dielectric liquid is poured into the containment tank. Throughout the liquid insulation installation, a vacuum is used to help remove moisture. Eventually, the containment tank is sealed shut. There is a bit of space allowed between the liquid and the cover of the containment tank for thermal cycling (expansion/contraction).
Dry insulation
Dry-transformer windings are insulated by preheating the conductor coils, dipping the conductor coils in a varnish and then curing the conductor coils in an oven (baking). Ducts are installed in the transformer windings. Cool air flows through the ducts while heat is dispersed from the electrical discharges of the transformer.

One frustrating drawback with iPod and iTunes is that pictures and photos are saved onto your iPod in a seemingly random fashion. But if you want to save a comic book or a slide show onto your iPod, you will want to organize your pictures so they are displayed in order. Follow these steps to organize pictures on an iPod.
Instructions
1. Create a new folder. Right-click anywhere on your desktop. Select "New" from the list and then "Folder." Name it "iPod Photos."
2. Find pictures you want to import to your iPod. These can be from the Internet or on your hard drive.
3. Copy them to your "iPod Photos" folder. If it is on your hard drive, highlight the photos and hit "Ctrl" and "C" at the same time. Then open your "iPod Photos" folder and hit "Ctrl" and "V" at the same time.
4. Rename the photos. Begin each filename with a number beginning from 001. Number them in the order you want them to appear. For example, "001 - peru.jpg" first, then "002 - peru.jpg" next, all the way up to "999 - peru.jpg." It is important that you number them in this fashion.
5. Open iTunes and connect your iPod. Now click your "iPod" icon. Click on the "Photos" tab.
6. Click "Sync Photos From:" and then select your "iPod Photos" folder. Click "Apply."
7. Update your iPod. Click "File" then "Sync iPod."
8. Disconnect your iPod and view the photos.

A typical Radio Frequency Identification (RFID) system consists of a small computer chip known as a tag or transponder, a reader or scanning device, and a computer. Information is stored on the tag to be read by the scanner or reader. RFID tags can be attached to objects such as merchandise, packages or vehicles, or embedded in the tissue of animals or sometimes people, allowing the tagged object to be identified, located and tracked.
Asset Tracking
RFID technology is widely used in the private and public sectors for asset tracking and inventory management. Attaching RFID tags to items that need to located quickly or that are frequently lost or stolen can improve business efficiency and protect against theft. Indeed, one of the first commercial applications of RFID was an anti-theft system widely employed in stores. A simple RFID tag -- featuring just a single bit, which can be turned on or off -- is attached to merchandise in a store and read at store exits. When you pay for the item, the bit is switched off. An item not paid for causes an alarm to sound when the tag is read at the exit.
Supply-chain Management
For many years, RFID has been used for supply-chain management in the manufacturing and retailing industries. The low cost, invisibility, and ease of deployment of an RFID system makes it more appealing than alternative technologies, such as bar codes. In manufacturing, RFID technology is used to track individual parts, helping to reduce defects and increase throughput. In retailing, evolution of the Electronic Product Code (EPC) standard -- a universal identifier with digits for manufacturer, product category, and item -- has led many leading retailers to use RFID to track shipments from suppliers.
Access Control
Another popular application of RFID technology is the provision of keyless electronic access to buildings or secure areas within buildings. The main advantage of RFID in these situations is that employees can simply wave an RFID tag in the vicinity of a door to unlock it. This faster and more convenient than keys or magnetic swipe cards, and because there is no physical contact between the tag and the reader, there's less wear-and-tear.
Motor Vehicles
Active RFID tags that are battery powered can be installed in motor vehicles and read, typically at a distance of 100 feet or more, by a reader mounted in a highway toll booth. This allows vehicles to pass through the toll booth without stopping, reducing traffic congestion; such technology is also being investigated by fast-food restaurants as a potential drive-through payment method.

Leaks begin when the seal on your skylight has failed.
Skylights are popular with homeowners for the added natural light they bring into rooms. They are not so popular, though, when they begin to leak. This is a common problem with skylights as the watertight seal used during installation can degrade over time or become damaged in a storm. You can easily fix a leaking skylight. The most important part of the job is identifying which of the two areas of the skylight assembly is leaking. It may be both, but is usually only one.
Instructions
Determine the Location of the Leak
1. Set your ladder against your house so you can easily access your skylight to perform a water test to locate the leaks. Have a helper hold the ladder steady as you climb up to the roof. Once on the roof, have the helper hand you the garden hose.
If you're working more than one story above the ground, tie a piece of rope to the hose. Rather than carry the hose as you climb the ladder, hold onto the rope. Once you're upon the roof, pull up the hose.
2. Run water over the glass of the skylight first to see if the seal between the glass and the frame is leaking. Have a second helper inside--where they can see the skylight--tell you if water's leaking in. Make sure the helper dries off any water that leaks inside the house with a clean towel before testing the next seal on the skylight.
3. Run water over the flashing between the skylight and the roof shingles. The flashing is the smooth metal sheet attached to the skylight frame and lays over the top of the shingles. This allows water to run off the skylight and onto the roof. Have your helper inside spot any leaks during this test and to dry off any water that may leak through.
Repair the Seal between the Skylight Glass and Frame
4. Clean the glass of the skylight with glass cleaner and towels. Pay particular attention to where the glass meets the frame and remove any dirt or debris from that seam.
5. Load a cartridge of marine grade silicone caulk into your caulk gun. Marine grade is recommended as it is the most reliably waterproof standard on the market. Alternatively, you can use any silicone caulk that's clearly labeled as "waterproof."
6. Place a continuous bead of caulk into the seam between the glass and the frame of the skylight. Be careful to wipe off any excess caulk from the glass with a damp paper towel.
Repair the Seal between the Flashing and the Roof
7. Slide a thin metal paint scraper between the flashing and the shingles. Pull the scraper all the way around the flashing to completely break the seal on the old caulking. If your flashing has been placed beneath the shingles (as some styles allow), use the claw end of a hammer to pry up the shingles to access the flashing.
8. Pry up gently on the flashing and remove the old caulking by pulling it out of place with your fingers.
9. Clean between the flashing and the roof or shingles by using a paint brush to sweep away any debris between the two.
10. Add a cartridge of silicone caulk (marine-grade works best, but any waterproof caulk will do) into your caulk gun.
11. Apply a continuous bead of caulk under the flashing, near its edge, and press down the flashing. If your flashing was covered by shingles, reinstall the shingles. Caulk over each nail hole as you place the material.

The Pentax Optio 33L is a small, hand-held, point and shoot digital camera. Pentax designed these cameras with lenses that retract into the camera housing when the unit is off, preventing damage to sensitive optics. The Optio takes CF cards to hold images and uses a rechargeable lithium battery to power the camera. If the lens won't open when you press the power button on your Optio 33L, there are some troubleshooting tips to run through to try and get your camera functioning again.
Instructions
1. Open the battery compartment and remove the battery. Place the battery into the Optio battery charger and plug the charger into a wall socket. Look for a green or red light on the charger. If red, the battery needs to be charged. Charge the battery and place it in the camera. Press "Power" to see if the recharged battery fixes the problem.
2. Check the CF card slot and covering. If the CF card is loose or the cover is ajar, the unit will not power on. Push the CF card into the housing and close the CF cover. Try the power again.
3. Open the battery compartment again and remove the battery. Check to see if the battery was installed properly, and the connectors are lined up. Brush off the battery connection points, install properly and turn the unit on.

An individual has a right, with a few exceptions, in the U.S. and other countries, to keep medical records private. Doctor/patient confidentiality has long been the ethical standard. More recently, the federal government enacted the Health Insurance Portability and Accountability Act (HIPAA) in response to the electronic storage of records. However, patients generally have the right to their own records and can get possession of x-rays easily.
Instructions
1. Contact the hospital or other facility where the x-rays were taken. Information on access your records should have been provided to you at the time of the procedure pursuant to HIPAA.
2. Find out what the procedure is at a particular facility to get possession of an x-ray. Some hospitals will take your name and birth date over the phone and have the x-ray ready when you arrive. Then you will have to provide personal information, probably a photo I.D., and sign a form.
3. Request in writing that your x-rays be provided to a third party if that is your wish.
4. Be prepared to pay a reasonable fee if you intend to keep the x-ray. Most hospitals or doctor's offices will ask that you return them for safekeeping with the assurance that you always have access to them. Also, you will probably be asked why you want the x-rays. For instance, they may want to know which doctor is requesting them.
5. File a complaint with the U.S. Dept. of Health and Human Service's Office of Civil Rights if you are unable to get possession of your x-rays (see Resources). You may also be able to file a complaint with your state.
For a serious photographer, taking the perfect picture only begins with the camera. Accessories, like the camera lens, can make the difference between a photo that is ordinary and one that is worthy of a gallery show. In truth, the camera lens is much more than the little shuttered eye on the front of a camera. It is actually a set of several lens elements inside the camera, all of multiple sizes.
Instructions
1. Be familiar with the camera. You must know not only what type of lenses are available but how they will function with your particular camera. Read the owner's manual.
2. Determine the type of lens needed. Prime lenses allow for sharper shots in low light, while zoom lenses produce the best action shots and telephoto lenses result in great long-distance shots. Pick the one that best fits your shooting needs.
3. Determine the focal length needed. Focal length determines the viewing angle of the lens. This includes everything from wide angle to slight telephoto, with the field of view becoming narrower as the focal length is increased. Choose a lens with focal length that is variable, one that you can use in more than one setting.
4. Check to see if the different brands of lenses are interchangeable. Sometimes a cheaper or more unusual lens can be acquired for your camera although it was made for another camera. The best way to know if you can use a lens on your camera is to take it to a reputable camera shop and ask.
5. Take your camera wherever you go to look for a lens. By taking your camera along you can find a lens that corresponds with your camera's idiosyncrasies. For example, blurry photos can be a result of slow shutter speed when a camera is held by the photographer. With your camera in hand, look for a lens with image stabilization to reduce shaking and vibration.

Nickel is one of the most common metals used by humans. It is commonly used in plating other kinds of metals and in producing numerous alloys such as nickel-titanium. Apparently, nickel is a common cause of contact dermatitis, particularly in the field of orthodontics, whereas nickel-free titanium is considered hypoallergenic.
History
In their article "Nickel Allergy and Orthodontics," published in the Journal of Orthopedics, Gerry Rahilly of Leeds Dental Institute and N. Price of Mayday Hospital note that the first case of allergic reaction to nickel was among workers in the nickel plating industry, which was reported at the end of the 19th century. In 1925, allergic response to nickel and nickel-containing alloys such as nickel-titanium was finally considered a medical condition.
Nickel and Titanium
According to Rahilly and Price, nickel-titanium alloys may have more than 50 percent nickel content, which is potentially enough to elicit signs of allergic reactions. However, the use of nickel-free titanium is a good measure in preventing nickel allergy.
Allergic Reaction
Rahilly and Price state that nickel acts as an antigen that causes type IV hypersensitivity or delayed allergic reaction. On exposure to nickel, primary immune response is induced wherein the body begins to produce antibodies against nickel, leaving no signs of allergy. However, re-exposure to nickel leads to more visible reactions.
Symptoms
According to the Astma-Og Allergiforbundet website, nickel allergy is a form of contact allergy that elicits eczema. Signs of contact eczema include red skin and swelling, sometimes with small or large blisters and oozing sores, severe itching, dryness and cracks.
Diagnosis
In addition to the thorough evaluation of the patient's medical history, a dermatologist may perform patch tests using 5 percent nickel sulphate in petroleum jelly to confirm nickel allergy.
Treatment
Apply a soothing moisturizing cream minutes before applying a doctor's prescribed layer of cortisone preparation. Avoid using items with parts made of nickel, nickel-titanium or any other nickel alloy. Nickel allergy treatment will be ineffective if contact with nickel is unavoidable. Consider using gold plate or titanium instead of nickel or nickel alloy.
Smoking cigarettes in a house can result in a significant odor problem, because the smoke will permeate walls, flooring, furniture and upholstery. When you wish to rectify an odor problem, hide cigarette smoke in the home by introducing other, more pleasant aromas into the home. This can be useful, especially if you are trying to sell your house, or if you quit smoking and want to remove the smoke smell.
Instructions
1. Light scented or odor-neutralizing candles, and place at least one in each room where you notice cigarette smoke odors. If you use odor-neutralizing candles, they can help add an enjoyable scent to your home while neutralizing the smoke odors you are trying to hide. Keep the candles burning as long as you wish to cover up the odors.
2. If you do not wish to burn candles, use reed diffusers dipped in scented oil in rooms where you wish to cover cigarette odors. The reeds will absorb the scented oil and disperse the scent into the room. Reed diffusers can be effective for hiding cigarette odors.
3. Fill a saucepan with 1 cup of potpourri (rose petals, cinnamon sticks, cloves, and orange peels, for example), and add 2 cups of water. Place the saucepan onto a stove burner, and set the burner to medium. When the water simmers, turn the heat down to low, and allow the potpourri to simmer on the stove top for several hours. Check the water level periodically, and add more water when needed.
4. Bake homemade cookies to cover the odors of cigarette smoke. The aroma of fresh-baked cookies will fill your home with delicious cookie smells, hiding the odor of cigarettes.
5. Fill small dishes with 1/2 cup of white vinegar. Set one or two dishes per room on tables or bookshelves. The vinegar will absorb and neutralize the cigarette odor.
6. Sprinkle carpet freshener or baking soda liberally over carpeting to cover it with an even layer of product. Allow the carpet freshener or baking soda to sit on the carpeting for 15 minutes to absorb the odors, and then vacuum.
7. Run an air purifier in rooms where you wish to remove cigarette odor. The filters in an air purifier will clean the air and remove distasteful smells. Continue running the air purifier until you cannot smell the cigarette odor.
The SLR camera offers many advantages for focus and exposure control.
The single-lens reflex camera (SLR) is the camera of choice for many photographers who wish to move beyond the amateur level of photography. It is more portable than large format cameras yet has superior focusing abilities over point-and-shoots. Depending on what subjects and under what conditions you wish to photograph, certain key characteristics of an SLR may be to your advantage.
Close-Up Images
SLRs are an improvement over point-and-shoots when creating images up close to a subject. The viewfinder of the point-and-shoot camera is located off to one side and does not match the angle of view that the camera's lens captures. This results in what is known as "parallax error:" when the composition of a close-up image does not match what is seen in the viewfinder. An SLR camera eliminates this problem with its mirrors and pentaprism. A mirror at a 45-degree angle behind the lens bounces the image into a pentaprism on top of the camera body, providing an image in the viewfinder that matches exactly what the lens "sees."
Viewfinder Perspective
Because of its pentaprism, SLR cameras provide a more natural way to view compositions in the viewfinder. This is opposed to large-format cameras that contain no mirrors. These cameras require that you focus by viewing a large frosted-glass screen under a hood that blocks light. The image is projected onto the screen in the manner in which light is converted through the lens: reversed both left-to-right and top-to-bottom. An SLR's pentaprism corrects the orientation, avoiding this awkward way to compose.
Exchangeable Lenses
As opposed to point-and-shoots, the vast majority of SLRs have exchangeable lenses. This allows you to adapt to different shooting situations by using varying focal lengths of lenses. These include wide-angle lenses, normal lenses, long lenses or zoom lenses that contain all options. While many point-and-shoots offer zoom options, the optics of SLR lenses are far superior and allow for manual focusing which creates sharper images.
Faster Shutter
SLR cameras are capable of faster shutter speeds than their large-format counterparts. The SLR camera's shutter is a "focal plane" style: a curtain that moves either from left-to-right or top-to-bottom and is located in the camera body. Large-format cameras employ a "leaf" style, located in the lens and composed of a series of overlapping leaves that open in a circle from the center. A leaf shutter is more complicated in that it must open and close again to make an exposure, while a focal plane shutter makes one sweeping motion. Because of the dual motion of the leaf shutter, it is usually not capable of shutter speeds as fast as those of the SLR.
Manual Exposure Controls
A major advantage over most point-and-shoot cameras is the manual or semi-manual exposure control available with SLRs. You can choose your shutter speed to control how much motion blur or frozen action you want in an image. Aperture controls how much of the depth of the image remains in focus. SLRs allow you to control at least one of these, if not both, while most point-and-shoots do not offer these controls.

Zoom lenses for cameras come in two basic types: optical zoom and digital zoom. With an optical zoom lens, the focal length of the lens is variable within a range. Digital zoom lenses do not actually zoom; instead a portion of the image area is enlarged and cropped to simulate a zoom. Some point-and-shoot cameras have both optical and digital zoom.
Optical Zoom
Optical zoom lenses actually move in and out to change the focal length of the lens, while remaining in focus. The ranges are expressed in focal length. A focal length of 50mm to 55mm is considered a "normal" perspective for a 35mm film camera or DSLR with a similar-sized sensor. A zoom lens with a focal length from 55mm to 200mm is a telephoto zoom lens. A zoom lens from 24mm to 55mm is considered a wide-angle zoom lens.
Digital Zoom
Digital zoom lenses do not have the quality of an optical zoom lens. They work by taking a sample of your subject, and as you zoom they magnify the sample. The higher the zoom, the worse the quality. Digital zooms can result in pixilation. Digital zoom lenses are described in magnification factors from a normal perspective of 55mm. A 2X zoom will yield a result similar to a 110mm optical zoom.
Image Quality
Although optical zoom lenses are considered to be of higher quality than digital zoom lenses, all lenses exhibit different characteristics. Lenses with glass elements perform better than lenses with plastic elements. If you need a long lens, it is better to buy a telephoto converter than to use a digital zoom lens. There is a significant quality difference between the two types of zoom lenses.
Point-and-Shoot Cameras
Most point-and-shoot cameras use a combination of optical and digital zoom lens. You will notice that as you zoom, the lens extends a little to alter the focal length. If you zoom further, the image is zoomed using a digital zoom. Normally point-and-shoot cameras will offer an optical zoom of 35mm to 110mm and then a 2X, 4X or even 8X digital zoom. Your image quality will suffer when you use the digital zoom.
Digital Single-Lens Reflex Cameras (DSLR)
A digital single-lens reflex camera use lenses that have optical zoom only. If you need a different focal length, you need to change lenses. With these cameras you can also use telephoto and wide-angle converters to alter the focal length. Converters are cheaper than new lenses but vary in quality. You can get cheaper ones with plastic elements, but it does not make sense to do that with a Nikon, Canon or other high-quality lens. To maintain the quality, it is better to buy an adapter from your camera manufacturer or third-party quality manufacturer that uses optical glass elements.
