nising the transmitter" or "Registering a
new transmitter". You can also call the hot-
line mentioned above. Problems when programming
If you experience problems when program-
ming the garage door opener integrated in the
rear-view mirror, note the following:
R
check the transmitter frequency of garage
door remote control A(this can usually be
found on the rear of the remote control).
R change the batteries in garage door remote
control A.This increases the likelihood
that garage door remote control Awill
send a strong and precise signal to the
integrated remote control in the rear-view
mirror.
R when programming, hold garage door
remote control Aat different distances
and angles from the transmitter button that
you are programming. Try various angles at
distances from 5 to 30 cm or the same
angle but varying distances.
R If there is another remote control for the
same garage door drive, perform the pro-
gramming steps again using the other
remote control. Before performing these
steps, make sure that new batteries have
been fitted in the garage door remote con-
trol.
R Align the aerial cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.
Opening or closing the garage door Once programmed, the integrated remote
control will assume the function of the garage
door system's remote control. Please also
read the operating instructions for the garage
door system.
