Radio Signals for Canada and
Some Gate Operators
For questions or programming help
call 1-800-355-3515 or see
www.homelink.com.
Canadian radio-frequency laws and
some U.S. gate operators 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
rapidly. Proceed with Step 3 under
“Programming the Universal Remote
System” to complete.
