place so that the sensor bracket is flush against the track.
2. Slide the hex screw through the sensor.
3. Attach the sensor to the bracket with the wing nut. Make sure the lens is not obstructed by
the bracket.
Repeat the steps with the other sensor on the opposite door track. Both lenses must face each other.
