Garage Door Opener Transmitter: Description and Operation
Description
DESCRIPTION
Some vehicles are equipped with a Universal Transmitter transceiver (4). The universal transmitter transceiver (4) is located in the headliner (5) just to
the rear of the courtesy/reading lamps (1). The only visible component of the universal transmitter are the three transmitter push buttons. The three
universal transmitter push buttons are identified with raised buttons and contain a transmit indicator that lights during operation and programming
functions.
Each of the three universal transmitter push buttons controls an independent radio transmitter channel. Each of these three channels can be trained to
transmit a different radio frequency signal for the remote operation of garage door openers, motorized gate openers, home or office lighting, security
systems or just about any other device that can be equipped with a radio receiver in the 280 to 435 MegaHertz (MHz) frequency range for remote
operation. The universal transmitter is capable of operating systems using either rolling code or non-rolling code technology. The system will not
transmit operating signals if the Vehicle Theft Security System is armed.
The universal transmitter cannot be repaired, and if inoperative or damaged, the complete module assembly must be replaced.
