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 your Universal Home Remote. The motor head dip switch settings can also be used when you do not have the original hand held transmitter. Example of Eight Dip Switches with Three Positions Your panel of switches may not appear exactly as they do in the examples, but they should be similar. The switch positions on your hand-held transmitter may be labeled as follows: • A switch in the up position may be labeled as "Up or "On." • A switch in the down position may be labeled as Example of Eight Dip Switches with Two Positions "Down or "Off." • A switch in the middle position may be labeled as "Middle," "0," or "Neutral." 2-53
