Replacing the Heart Rate Monitor Battery
1
Remove the sleeve
À
from the heart rate monitor module.
2
Use a small Phillips (00) screwdriver to remove the four
screws on the front of the module.
3
Remove the cover and battery.
4
Wait 30 seconds.
5
Insert the new battery under the two plastic tabs
Á
with the
positive side facing up.
NOTE:
Do not damage or lose the O-ring gasket.
The O-ring gasket should remain around the outside of the
raised plastic ring.

Replace the front cover and the four screws.
Observe the orientation of the front cover. The raised screw
Â
should fit in the matching raised screw hole on the front
cover.
NOTE:
Do not overtighten.
7
Replace the sleeve.
After you replace the heart rate monitor battery, you may need
to pair it with the device again.
