Radio Signals for Some
Gate Operators
For questions or programming
help, see www.homelink.com/
gm or call 1-800-355-3515.
For calls placed outside the
U.S., Canada, or Puerto Rico, international rates will apply
and may differ based on
landline or mobile phone.
Some gate operators and
radio-frequency laws require
transmitter signals to time out
or quit after several seconds
of transmission. This may not
be long enough for the
Universal Remote system to
pick up the signal during
programming.
If the programming did not
work, replace Step 2 under
“Programming the Universal
Remote System”
with the
following:
Press and hold the Universal
Remote system button while
pressing and releasing the
hand-held transmitter button
every two seconds until the
signal has been successfully
accepted by the Universal
Remote system. The Universal
Remote system indicator light
will flash slowly at first and
then change to a rapid flash or
continuous solid-light. Proceed
