Replacing the Battery:

Locate the battery compartment, which is in the top right of the caliper body with the caliper lying horizontally. To open this compartment, you will need to remove the screw that holds it to the body. You’ll find the screw on the backside of the caliper, in the top corner directly behind the battery compartment.
