Aligning the Infrared Photo Beam
1.  A lit GREEN LED indicates that the 
photo beams have power.
2.  Adjust the beams so that the sending 
unit and receiving unit are aligned. 
When the RED LED lights up the 
photo beams are aligned.
3.  If an object blocks the infrared beam 
while the door is closing, the door will 
stop, then reverse and fully open (the 
opener’s light will  ash three times).
4.  As a safety feature, the opener will 
ignore signals from all remote controls 
if the door is open and the photo 
beam is blocked or out of alignment. 
In this case, the door can be forced 
closed by pressing and holding the 
wall station’s button (be sure the door 
area is in clear view).

turns on for 5 minutes when door moves down to the fully closed position. The beam power can be 
restored for 5 minutes by pressing the light button on the wall station.

opening to the receiver.
