Instruments and Controls
This system can replace up to
three remote control
transmitters used to activate
devices such as garage door
openers, security systems,
and home automation devices.
These instructions refer to a
garage door opener, but can
be used for other devices.
Do not use the Universal
Remote system with any
garage door opener that does
not have the stop and reverse
feature. This includes any
garage door opener model
manufactured before April
1, 1982.
Keep the original hand-held
transmitter for use in other
vehicles as well as for future
programming. Erase the
programming when vehicle
ownership is terminated. See

To program a garage door
opener, park outside directly in
line with and facing the garage
door opener receiver. Clear all
people and objects near the
garage door.

transmitter has a new battery
for quick and accurate
transmission of the
radio-frequency signal.
