How to change the batteries in the power meter.
- Small #0 Phillips head screwdriver

To replace the power meter batteries:
- Remove the battery cover screws using a small #0 Phillips head screwdriver, then slide the battery cover off of the power meter housing.
- Remove existing batteries from the housing. If needed, rotate the crank into the downward position so the batteries slide out.
- Insert (2) new AA batteries according to the orientation shown on the power meter.
Replace the battery cover and tighten the screws. Do not over-tighten the screws as this may damage the battery case.
