DESCRIPTION AND OPERATION
Universal Transmitter
Overview
The universal transmitter operates garage doors, gates and home or office lighting and security systems.
System Operation
Universal Home Transmitter
The universal transmitter learns a hand-held transmitter radio frequency code and stores the code in memory. It consists of 3 buttons, each with its own indicator lamp. Once the universal transmitter code is stored, the universal transmitter emits the radio frequency of the hand-held transmitter when the corresponding button is pressed. The universal transmitter can store 3 unique transmitter codes at a time. The universal transmitter and LH vanity mirror lamp share the same power and ground circuits. Both components are part of the LH sun visor.
