Instructions to Replace the HRM Battery:

1. Remove the colored ring around the module.

2. Unscrew the four screws holding down the cover to the module.

   • Use the #00 size Phillips-head screwdriver.

   • Partially unscrew all 4 screws evenly, before fully unscrewing each one.

   • If a screw is stripped or difficult to remove, consider placing a rubber band on the tip of the screwdriver to provide better grip.

3. Carefully remove the cover.

4. Turn over the strap and tap the back to get the battery out.

5. Wait 30 seconds with the battery out before moving to step #6.

6. Carefully insert the new battery ensuring that the positive side is facing out as shown below.

   

7. Place the cover back on and tighten the four screws.

NOTE: To ensure that the battery compartment is not compromised, verify that the red o-ring is properly in place, the battery cover is installed correctly, and be sure to not overtighten the screws as this could cause damage to the module. Once confirmed, insert the module back into the colored ring of the strap.
