Gate Operator And Canadian Programming; Using Homelink - Hummer 2003 H2 Owner's Manual

Gate Operator and Canadian Programming

-
Canadian radio frequency laws require transmitter
signals to "time out" or quit after several seconds
of transmission. This may not be long enough for
HomeLink to pick up the signal during programming.
Similar to Canadian law, some U.S. gate operators are
manufactured to "time out" in the same manner.
If you live in Canada or you are having difficulty
programming a gate operator by using the
"Programming HomeLink" procedures (regardless of
where you live), replace Step 3 under "Programming
HomeLink" with the following:
Continue to press and hold the HomeLink button while
you press and release every two seconds (cycle) your
-
hand held transmitter until the frequency signal has
been successfully accepted by HomeLink. The indicator
light will flash slowly and then rapidly. Proceed with
Step 4 under "Programming HomeLink" to complete.
2-74

Using HomeLink

Press and hold the appropriate button on HomeLink for
at least half of a second. The indicator light will come
on while the signal is being transmitted.
Erasing HomeLink Buttons
To erase programming from the three buttons, press and
hold down the two outside buttons until the indicator
light begins to flash (after 20 seconds). Release both
buttons. Do not hold for longer than 30 seconds.
HomeLink is now in the train (learning) mode and can
be programmed at any time beginning with Step 2 under
"Programming HomeLink".
Individual buttons can not be erased, but they can be
reprogrammed. See "Reprogramming a Single
HomeLink Button" next.
