Operating The Transmitter - GMC 2000 Envoy 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 held 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 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 Door Opener with a
"Rolling Code" Feature (If Equipped)
If you have not previously programmed the
-
hand held transmitter to the HomeLink Transmitter,
see "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.
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.
