Operating The Transmitter - GMC 2001 Yukon XL Owner's Manual

Canadian Owners: During programming, the
-
hand held transmitter may automatically stop
transmitting after one or two seconds. In this case, you
-
should press and re press the button on the hand
transmitter every two seconds without ever releasing the
button on the HomeLink Transmitter. Release both
buttons when the indicator light on the HomeLink
Transmitter begins to flash rapidly.

Operating the Transmitter

Press and hold the appropriate button on the
R
HomeLink Transmitter. The indicator light
comes on while the signal is being transmitted.

If the hand held transmitter appears to program the
HomeLink Transmitter but does not open your garage
door, and if the garage door opener was manufactured
after 1996, the garage door opener may have a "rolling
code" system. A rolling code system changes the code
of the garage door opener every time you open or close
the garage door.
To determine if you have this system, press the
button on the HomeLink Transmitter that you have
programmed already. If the indicator light flashes
rapidly for one to two seconds, then turns solid, the
garage door opener has a rolling code system. In a
rolling code system, the garage door motor head unit
must be trained to the HomeLink Transmitter.

Training a Garage Opener with a "Rolling
Code" Feature (If Equipped)
If you have not previously programmed the hand
-
held
transmitter to the HomeLink
"Programming the Transmitter" listed previously.
If you have completed this programming already, you
now need to train the garage door opener motor head
unit to recognize the HomeLink Transmitter. Refer to
your garage door opener owner's manual for the proper
transmitter training procedure for your garage door
opener brand.
1. Find the training button on the garage door opener
motor head unit. The exact location and color will
vary by garage door opener brand. If you have
difficulty finding the training button, refer to your
garage door opener owner's manual.
Because of the steps involved, it may be helpful
to have another person assist in programming
the transmitter.
2. Press the training button on the garage door
opener motor head unit. An indicator light will
begin to flash when the motor head unit enters the
training mode.
Following this step, you have 30 seconds to
start Step 3.
