Insert a screwdriver into the slot at the top of the case and twist to pry off the cover. Set the cover aside.
2

Press the lock release button on the lower left end of the case with the screwdriver and slide downward to remove the mounting plate.

Thread the wires through the corner hole in the lower right-hand corner of the mounting plate, then place the plate onto the designated area. Make sure the holding posts point upwards, and secure with the included flat head screws.

Line up the slots on each side of the case with the holding posts on the mounting plate. Slide the unit downward until the locking tab clicks.
5

Mount a magnet to the right of the transmitter by aligning it with the guide marks on the mounting plate and case, if you decide to use a magnetic reed switch.
6

Connect the contact loop, if applicable, to the transmitter's terminals, located beneath the battery compartment.

Insert the battery into the compartment with the positive terminal pointing up, then replace the transmitter's cover. Align the hooks at the bottom end of the case, and snap the cover shut.
