Problems when programming
If you are experiencing problems programming
the integrated garage door opener on the rear-
view mirror, take note of the following instruc-
tions:
R
Check the transmitter frequency used by
garage door drive remote control A and
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remote control A for the garage door drive.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequency range of 280 to
433 MHz.
R
Replace the batteries in garage door 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.
R
When programming, hold remote control A
at varying distances and angles from but-
tons ; to ? which you are programming.
Try various angles at a distance between
2and 8 inches (5to 20 cm) or at the same
angle but at varying distances.
R
If another remote control A is available for
the same garage door drive, repeat the
same programming steps with this remote
control A. Before performing these steps,
make sure that new batteries have been
installed in garage door drive remote control
A.
R
Note that some remote controls only trans-
mit for a limited amount of time (the indica-
tor lamp on the remote control goes out).
Press button B on remote control A again
before transmission ends.
R
Align the antenna cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.

garage door opener performs the function of
