Polar F6 heart monitoring systems allow you keep track of your heart rate while exercising. The factory-installed batteries in Polar F6 wrist watch units are designed to last for approximately two years, but if you use the backlight feature often you may find yourself needing a battery replacement much sooner. If you don't have the time, money or patience to send your F6 to Polar for service, you can change the battery yourself at home in just minutes.
Instructions
1. Lay the Polar F6 wrist watch unit face down on a flat surface that has been covered with a soft cloth. Use an optical-sized Phillips screwdriver to take out the four screws that hold the watch's back cover; set the screws and cover aside.
2. Remove the internal watch unit from the watch casing; the internal unit should easily slide free of the casing.
3. Examine the internal watch unit to locate the metal strap that holds the battery in place. Use an optical-sized flat-blade screwdriver to raise the strap and pry the spent battery from the battery compartment. Dispose of the battery or recycle it if suitable facilities are available.
4. Insert a new CR2032 battery into the battery compartment of your Polar F6. Make sure that the new battery is positioned just as the old one was. Lower the metal strap over the new battery and apply gentle pressure to the strap until it clicks into place.
5. Slide the internal unit back into the watch casing and replace the back cover. Reinsert the four screws and tighten them with the optical-sized Phillips screwdriver.
