garage door opening system's operating
instructions, e.g. the sections on
"Synchronizing the transmitter" or
"Registering a new transmitter". You can
also call the hotline mentioned above.
Notes on programming the remote
control
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals a few seconds after broadcasting.
Therefore, these signals may not last long
enough for the integrated remote control to
recognize the signal during programming.
Comparable with Canadian law, some U.S.
garage door openers also have a built-in
"interruption".
If you live in Canada or have difficulties
programming the garage door opener
(regardless of where you live) when using the
programming steps (see above), proceed as
follows:XPress transmitter button ( ;, = or ?) and
hold it down during the following steps until
the setup has been completed
successfully.XAt the same time, press transmitter button
B of the garage door remote control for
two seconds, then release it for two
seconds, then press it again for two
seconds.XRepeat this sequence on transmitter
button B of the garage door remote
control until the frequency signal has been
saved.XIf the setup procedure is successful,
indicator lamp : flashes once slowly and
goes out after a few seconds.XContinue with the other programming
steps (see above).Problems when programming
If you have problems when programming the
integrated remote control, please note the
following:
R Check the transmitter frequency of garage
door remote control A (which can usually
be found on the rear of the remote control).
The integrated remote control is
compatible with devices that operate at
frequencies between 280 and 390 MHz.
R Replace the batteries in garage door
remote control A. This increases the
likelihood of garage door remote
control A sending a strong and precise
signal to the integrated remote control on
the rear-view mirror.
R When programming, hold garage door
remote control A at varying distances and
angles from the transmitter button which
you are programming. Try different angles
at a distance of 2 to 12 inches (5 to 30 cm)
or the same angle at different distances.
R If there is another garage door remote
control for the same device, perform the
programming steps again using the remote
control. Before performing these steps,
make sure that new batteries have been
installed in the garage door remote control.
R Align the antenna cable of the garage door
opener unit. This can improve signal
reception/transmission.
Opening or closing the garage door
Once programmed, the integrated remote
control will assume the function of the garage
door system's remote control. Please also
read the operating instructions for the garage
door system.
XTurn the SmartKey to position 2 in the
