Problems when programming
If you are experiencing problems programing
the integrated garage door opener on the
rear-view mirror, take note of the following
instructions:
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 programming, hold remote control
R
A at varying distances and angles from the
button which you are programming. Try var-
ious 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
programming steps with this remote con-
trol. Before performing these steps, make
sure that new batteries have been installed
in garage door drive remote control A.
Note that some remote controls only trans-
R
mit for a limited amount of time (the indi-
cator lamp on the remote control goes out).
Press button B on remote control A again
before transmission ends.
Align the antenna cable of the garage door
R
opener unit. This can improve signal recep-
tion/transmission.
Opening/closing the garage door
After it has been programmed, the integrated
garage door opener performs the function of
the garage door system remote control.
