Notes on programing 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
programing. Comparable with Canadian law,
some U.S. garage door openers also feature a
"break".
Proceed as follows:
if you live in Canada
R
if you have difficulties programing the
R
garage door opener (regardless of where
you live) when using the programing steps.
Press and hold one of buttons ; to ? on

Press button B again for two seconds.
X
Repeat this sequence on button B of
X
remote control A until indicator lamp :
lights up green.
When indicator lamp : lights up green:
programing is finished.
When indicator lamp : flashes green: pro-
graming was successful. The next step is to
synchronize the rolling code.
Release button B of remote control A of
X
the garage door drive.
If indicator lamp : lights up red: repeat the
programing process for the corresponding
button on the rear-view mirror. When doing
so, vary the distance between remote con-
trol A and the rear-view mirror.
The required distance between remote
control A and the integrated garage door
opener depends on the garage door drive
system. Several attempts might be neces-
sary. You should test every position for at
least 25 seconds before trying another
position.
Problems when programing
If you experience problems programing the
integrated garage door opener on the rear-
view mirror, take note of the following instruc-
tions:
Check the transmitter frequency used by
R
garage door drive remote control A and
whether it is supported. The transmitter
frequency can usually be found on the back
of the garage door drive remote control.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequency range of 280 to
433 MHz.
Replace the batteries in garage door
R
remote control A. This increases the like-
lihood that garage door remote control A
will transmit a strong and precise signal to
the integrated garage door opener.
When programing, hold remote control A
R
at varying distances and angles from the
button which you are programing. Try vari-
ous angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
If another remote control is available for the
R
same garage door drive, repeat the same
programing steps with this remote control.
