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.
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.
