To open the case, follow these steps.

screws evenly spaced across the rear and three screws evenly spaced along each side of the case.

2. Slide the top backwards until its front flange slides free of the faceplate then lift it off.

3. Insert a small, flat screw-driver blade under the battery and in one of the slots of the plastic retainer

underneath the battery.
