Problems when programming
If you are experiencing problems programming
the integrated garage door opener on the rear-
view mirror, take not eofthe following instruc-
tions:
RCheck the transmitter frequenc yused by
garage door drive remotec ontrolAand
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remotec ontrolAfor the garage door drive.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequenc yrange of 280 to
433 MHz.
RReplace the batteries in garage door remote
control A.This increases the likelihood that
garage door remotec ontrolAwill transmit a
stron gand precise signal to the integrated
garage door opener.
RWhen programming, hold remotec ontrolA
at varying distances and angles from but-
tons ;to? which you are programming. Try
various angles at adistanc ebetween 2and
8i nches (5to 20 cm) or at the same angle but
at varying distances.
RIf another remotec ontrolAis available for
the same garage door drive, repeat the same
programmings teps with this remotec ontrol
A.B eforep erforming these steps, make sure
that new batteries have been installed in
garage door drive remotec ontrolA.
RNote that some remotec ontrols only transmit
for alimited amount of time (the indicator
lamp on t
he remotec
ontrol goes out). Press button
Bon remotec ontrolAagain before
transmission ends.
RAlign the antenna cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.
