Step-by-Step Instructions:

1. Remove the transmitter’s end cap by inserting the flat blade of a screwdriver in the cap’s slot and turning slightly counterclockwise.

2. Replace the end cap. Line up the projections on the cap with the openings at the edge of the case. Press the cap gently against the PCB and turn the cap (via its slot) slightly clockwise, thereby locking it in place.

NOTE: You may need to manually clear the tamper from the panel.
