▼ Gate operator/Canadian
Programming
Canadian radio-frequency laws require
transmitter signals to "time-out" (or quit)
after several seconds of transmission ―
which may not be long enough for
HomeLink to pick up the signal during
programming. Similar to this Canadian
law, some U.S. gate operators are designed
to "time-out" in the same manner.
