Replacing the Heart Rate Monitor Battery
Locate the circular battery cover on the back of the heart rate monitor.
- Use a coin to twist the cover counter-clockwise until it is loose enough to remove (the arrow points to OPEN).
- Remove the cover and the battery.
- Wait 30 seconds.
Insert the new battery with the positive side facing up.
NOTE: Do not damage or lose the O-ring gasket.
- Use a coin to twist the cover clockwise back into place (the arrow points to CLOSE).
After you replace the heart rate monitor battery, you may need to pair the heart rate monitor with the device again.
