Transmitter Programming









If the receiver malfunctions, it will be necessary to replace both receiver and transmitter. However, if only the transmitter is lost, be sure to supply the receiver code number so the new transmitter can be properly coded. Replacement receivers (with transmitters) and transmitters are available.

Batteries may not be supplied with some replacement transmitters. Be sure to check a replacement transmitter before attempting to activate the system.





Code Location

To obtain the code number required for replacement of the transmitter, inspection of the receiver will be necessary. Refer to Receiver Removal for receiver code.

(1) Separate the transmitter at the middle seam.

(2) Relieve tension on tabs and remove the printed circuit board.

(3) Inspect the circuit board for the code number.
