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".

Problems when programing

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
compatible 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
likelihood that garage door remote control
A will transmit a strong and precise signal
to the integrated garage door opener in the
rear-view mirror.
When programing, hold remote control A
R
at varying distances and angles from the
button that you are programing. Try various
angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
