7.3.2. 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 t1 does not receive a signal when the transmitter belt is active, you might need to replace the battery.
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.
