5-58 Instruments and Controls
If there is a row of dip switches
similar to the graphic above, the
garage door opener is a Fixed
Code unit. If you do not see a
row of dip switches, return to the
previous section for
Programming Universal Home
Remote Rolling Code.
Your hand-held transmitter can
have between 8 to 12 dip
switches depending on the
brand of transmitter.
The garage door opener receiver
(motor head unit) could also
have a row of dip switches that
can be used when programming
the Universal Home Remote.
If the total number of switches
on the motor head and
hand-held transmitter are
different, or if the dip switch
settings are different, use the dip
switch settings on the motor
head unit to program the
Universal Home Remote.
The motor head dip switch
settings can also be used when
the original hand-held transmitter
is not available.

The panel of switches might not
appear exactly as they do in the
examples above, but they
