Battery replacement in Polar FT60/FT80

Battery life time depends highly on how much you use the product. For estimated average battery life of your Polar FT60/FT80, please refer to product user manual.

The battery is inserted at the factory. The actual life of the first battery once the product is in your possession can therefore feel shorter than the estimated.

If you have the battery changed by a Polar-authorized service center, they only use Polar-approved components. With every battery change, a full periodic and water resistance check is done.

If you decide to change the battery yourself
1. Open the battery cover with a coin by turning it from Close to Open.

2. Remove the battery cover and lift the battery out carefully with a suitable sized small rigid stick or bar, such as a toothpick or small screwdriver. A non-metal tool is preferable. Be careful not to damage the metal sound element (*) or the grooves.

3. Insert a new battery with the positive (+) side outwards.
4. Replace the old sealing ring with a new one, fitting it snugly in the cover groove to ensure water resistance.
5. Put the cover back on and turn clockwise to CLOSE.
6. 'Please enter basic settings' is displayed. Press and hold the BACK button to skip the Basic settings.

If you re-enter the Basic Settings, the training computer thinks there is a new user and the STAR Program is turned off.

7. Go to Settings mode and adjust time and date.
8. To return to Time mode, press and hold the BACK button. Now your FT60/FT80 can be used normally.
