Garage Door Opener Description and Operation
The garage door opener (GDO) is fixed and rolling codecapable. Rolling code is a system that allows the code that thecustomers receiver receives from the GDO to change every time theGDO is used within operating range of the receiver. Rolling codeprogramming requires the customer to push a learn/program button onthe GDO receiver at their home. This button is usually located onthe receiver unit under a cover (light cover) on one end of theunit. The customer must follow the GDO manufacturers instructionsto program/learn the receiver to accept the Universal Home RemoteSystem as an authorized opener for their unit . When the receiverand the GDO are initially programmed together, a code isestablished and a new code is created for every new transmission.The software in the receiver recognizes the GDO and accepts the newcode.
The GDO is compatible with most, but not all types and brandsof transmitters. If a problem should occur with a compatibilityconflict with a transmitter, refer to1–866–572–2728.
The GDO is a transmitter operating between288–399-MHz. The power and range of thetransmitter is limited to comply with laws governing the generationof radio frequency interference (RFI). The transmitter isprogrammed by the user to accept the signal generated by the user'stransmitters.
The GDO has 3 buttons that may be programmed for individualtransmitter/receiver combinations to control up to 3 GDOs, securitygates, lighting systems, etc. Each button represents a transmittercode section of the transmitter, which operates separately from anyother button, and may be considered a separate transmitter.Operation consists of simply pressing a button to activate thecorresponding transmitter.
