The hand held transmitter can have between eight
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.
