Universal Transmitter

On some models, a Universal Transmitter transceiver is standard factory installed equipment. The universal transmitter transceiver is integral to the CMTC, which is located in the overhead console. The only visible component of the universal transmitter are the 3 transmitter push buttons. See Figure . The 3 universal transmitter push buttons are identified with 1, 2, or 3 light indicators so that they are easily identified by sight or by feel. Each of the 3 universal transmitter push buttons controls an independent radio transmitter channel. Each of these 3 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 286 to 399 MHz frequency range for remote operation. The universal transmitter is capable of operating systems using either rolling code or non-rolling code technology. The CMTC module displays messages and a small house shaped icon with 1, 2, 3 dots corresponding to the 3 transmitter buttons to indicate the status of the Universal Transmitter. The Universal Transmitter cannot be repaired, and is available for service only as a unit with the CMTC module. This unit includes the push button switches and the plastic module and display lens. If any of these components is faulty or damaged, the complete CMTC module must be replaced.
