receiving eye (with a green indicator light),, If an
obstruction breaks the light beam while the door is
closing, the door wilt stop and reverse to full open
position, and the opener tights will flash 10 times,
The units must be instafied inside the garage so that
the sending and receiving eyes face each other
across the door, no more than 6" (15 cm) above the
floor, Either can be installed on the left or right of the
door as long as the sun never shines directly into the
receiving eye Ions,
