Garage Door Opener Transmitter: Description and Operation
General Description
The garage door opener is located in the overhead console. The valet switch provides battery voltage to the garage door opener. If battery voltage is lost
due to a condition such as a dead battery, the garage door opener unit relies on the non-serviceable internal power backup supply. The unit is
programmed using the customer's hand-held transmitters for the garage door(s), electric entrance gates, or lighting and security systems.
The garage door opener is rolling code capable. Rolling code is a system that allows the code that the customers receiver receives from the garage door
opener to change every time the garage door opener is used within operating range of the receiver. When the receiver and the garage door opener are
initially programmed together, a code is established. After a code is established, a new code is created for every new transmission. The software in the
receiver recognizes the garage door opener and accepts the new code.
The garage door opener is compatible with most, but not all, types and brands of transmitters. If a problem should occur with a compatibility conflict
with a transmitter, call HomeLink(TM) at 1-800-355-3515.
