Programming the Transmitter
Do not use the transmitter 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.
Be sure that pe~ple arid objects Lire clear of the garclge
door- you ~1-e Iwogmmning!
Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. If you have not previously programmed a universal
channel, proceed to Step
2. Otherwise, hold down
the two outside buttons
on the universal transmitter
until the red light begins to flash rapidly
(approximately
20 seconds). Then release the
buttons. This procedure initializes the memory and
erases any previous settings for all three channels.
2. Hold the end of the hand-held transmitter against the
bottom surface
of the universal transmitter so that
you can still see the red light.

4.
Decide which one of the three channels you want to
program. Using both hands, press the hand-held
transmitter button and the desired button
on the
universal transmitter. Continue
to hold both buttons
through Step
4.
Hold down both buttons until you see the red light
on the universal transmitter flash rapidly. The rapid
flashing, which could take up to
90 seconds,
indicates that the universal transmitter has been
programmed. Release both buttons once the light
starts
to flash rapidly.
If you have trouble programming the universal
transmitter, make sure that you have followed the
directions exactly as described and that the battery
in the
hand-held transmitter is not dead. If you still cannot
program
it, rotate the hand-held transmitter end over end
and try again. The universal transmitter may not work
with older garage door openers that do not meet current
Federal Consumer Safety Standards.
If you cannot
program the transmitter after repeated attempts, consult
your
GMC dealer. Be
sure to keep the original hand-held transmitter
in case you need to erase and reprogram the
universal transmitter.
Operating the Transmitter
Press and hold the appropriate button on the universal
transmitter. The red light comes on while the signal is
being transmitted.
Note that the effective transmission range of the
universal transmitter may differ from the hand-held
transmitter and from one channel to another.

Training a Garage Opener with a “Rolling
Code” Feature
If you programmed the universal transmitter, but the
garage door will not open, and
if your garage door opener
was manufactured after
1995, your garage door may have
a security feature that changes the “code” of your garage
door opener every time it is opened or closed.
To determine if your garage door opener has this
“rolling code” feature, press the appropriate button on
the universal transmitter that was programmed.
If the
red light flashes rapidly for one to two seconds, then
turns solid, your garage door opener has this feature.
To program a garage door opener with the rolling code
feature, do the following:
1. Program your hand-held transmitter to the universal
transmitter by following the steps provided under
“Programming the Transmitter” earlier in
this section.

Remove the cover panel from the garage door
opener receiver.
It is located near the garage door
opener motor.
Locate the training button on the garage door opener
receiver. The exact location and color will vary
among brands.
Press the training button on the garage door opener
receiver for one to two seconds.
Return to your vehicle and press the programmed
button on the universal transmitter
until the red light
flashes rapidly (about two seconds).
Release the button, then press it again to confirm it
was programmed
to the garage door opener receiver.
You may now use either the universal transmitter or the
hand-held transmitter to open your garage door.

still have difficulty in programming and require
