Notes on programming the remote
control
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds.
Therefore, these signals may not last long
enough for the integrated garage door
opener. The signal is not recognized during
programming. Comparable with Canadian
law, some U.S. garage door openers are
designed to "time-out" in the same manner.

Problems when programming

the following instructions:
Check the transmitter frequency of garage
R
door drive remote control A. This can
usually be found on the back of the remote
control.
The integrated garage door opener is
compatible with devices that have units
which operate in the frequency range of
280to 433MHz.
Replace the batteries in garage door
R
remote control A. This increases the
likelihood that garage door remote control
A will transmit a strong and precise signal
to the integrated garage door opener in the
rear-view mirror.
When programming, hold remote control
R
A at varying distances and angles from the
button that you are programming. Try
various angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
If another remote control for the same
R
garage door drive is available, repeat the
