Programming tips
If you are having difficulty programming the
integrated remote control, here are some
helpful tips:
R Check the frequency of hand-held remote
control A (typically located on the reverse
side of the remote). The integrated remote
control is compatible with radio-frequency
devices operating between 280-390 MHz.
R Put a new battery in hand-held remote
control A. This will increase the likelihood
of the hand-held remote control sending a
stronger and more accurate signal to the
integrated remote control.
R While performing step 3, hold hand-held
remote control A at different lengths and
angles from the signal transmitter button
( ; , = or ?) you are programming.
Attempt varying angles at the distance of 2
to 12 inches (5 to 30 cm) away or the same
angle at varying distances.
R If another hand-held remote control is
available for the same device, try the
programming steps again using that other
hand-held remote control. Make sure new
batteries are in the hand-held remote
control before beginning the procedure.
R Straighten the antenna wire from the
garage door opener assembly. This may
help improve transmitting and/or receiving
signals.
i Certain types of garage door openers are
incompatible with the integrated remote
control. If you should experience further
difficulties with programming the
integrated remote control, contact an
authorized Mercedes-Benz Center, or call
the Mercedes-Benz Customer Assistance
Center (USA only) at
1-800-FOR-MERCedes (1-800-367-6372),
or the HomeLink ®
