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.
Example of Eight Dip Switches with Two Positions
Example of Eight Dip Switches with Three Positions
The panel of switches might not appear exactly as
they do in the examples above, but they should be
similar.
The switch positions on the hand-held transmitter
could be labeled, as follows:
•
A switch in the up position could be labeled
as "Up," "+," or "On."
•
A switch in the down position could be labeled
as "Down," "−," or "Off."
•
A switch in the middle position could be labeled
as "Middle," "0," or "Neutral."
