142 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
“Erasing Universal Remote
System Buttons”later in this
section.
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.
Make sure the hand-held
transmitter has a new battery
for quick and accurate
transmission of the
radio-frequency signal.
Programming the
Universal Remote System
Programming involves
time-sensitive actions and may
time out, requiring the
procedure to be repeated.
Read these instructions
completely before
programming the Universal
Remote system. It may help to
have another person assist
with the programming
process.
1. Hold the end of the hand-held transmitter
about 3 to 8 cm (1 to 3 in)
away from the Universal
Remote system buttons
with the indicator light in
view. The hand-held transmitter was supplied
by the manufacturer of the
garage door opener
receiver.
2. Press and release one of the three Universal
Remote system buttons to
be programmed. Press and
hold the hand-held
transmitter button. Do not
release the hand-held
transmitter button until
the indicator light changes
from a slow to a rapid flash
or continuous light. Then
release the hand-held
transmitter button.
Some garage door
openers may require
substitution of Step 2 with
the procedure under
“Radio Signals for Some
Gate Operators” later in
this section.
3. Press and hold the newly programmed Universal
Remote system button for
five seconds while
