5.4.2. Replacing the battery of the heart rate belt

The average expected battery life of the transmitter belt is 300 hours of use in ideal operating temperatures. If your Suunto t3 does not receive a signal when the transmitter belt is active, you might need to replace the battery.

1. Use a coin to open the battery compartment cover on the backside of the transmitter belt. Ensure that the O ring and all surfaces are clean and dry. Do not stretch the O ring.

2. Remove the old battery.

3. Place the new battery into the battery compartment with the positive side facing up.

4. With the O ring in the correct position, replace the battery compartment cover.

NOTE	If the threads of the battery compartment cover are damaged, please send
	your device to an authorized Suunto representative for service.

NOTE	Replace the battery with extreme care to ensure that your Suunto t3 remains
	water resistant. Careless battery replacement may void the warranty.
NOTE	Heavy use of the backlight will significantly reduce battery life.
