PC Board Battery
To prevent the PC Board from overheating, position the battery off of the board. The battery is
attached to a chip on the board using double-sided adhesive material. Follow the steps and
refer to the figure below.
1. Remove the battery from the PC Board by peeling the battery off the board. The adhesive
material should come off with the battery.
2. Position the battery with the adhesive material onto the side of the chassis as far away as
possible from the PC Board. This is the same chassis that the PC Board mounts onto.
