Garage Door Opener Transmitter: Description and Operation

DESCRIPTION





The universal transmitter transceiver is integral to the overhead console (3). The only visible component of the universal transmitter are the three transmitter push buttons (5) at the front of the overhead console. The buttons are marked with one, two or three illuminated dots, respectively, for identification of each channel.

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 is available for service only as part of the Electronic Overhead Module (EOM). The EOM includes the push button switches and the plastic module body. If the universal transmitter is damaged or becomes inoperative the EOM must be replaced, Universal Transmitter - Removal.
