Aligning and Testing the beams
• Plug in the opener. If your opener has the Multi-Function Door Control, make sure the Lock Feature is off. Red indi-
cator lights in both the sending and receiving eyes will glow if wiring connections and alignment are correct.
If the indicator lights are blinking (and the invisible light beam path is not obstructed), alignment is required.
• Loosen the receiving eye wing nut to allow slight rotation of unit. Adjust sensor vertically and/or horizontally until the
red indicator light glows.
• When indicator lights are glowing in both units, tighten the wing nut in the receiving eye unit.
