2. Use the 2 supplied M4 machine screws to secure the remote sensor back case. Prior to mounting,
clear the cutouts in the back case corresponding to the holes in the wall box using a screwdriver or the
like. Use the spacers and take care not to tighten the screws excessively. If the back case will not seat
well, cut the spacers to a suitable thickness.
