•Run paired wires from both sensors to the opener. Use insulated staples to secure wire to wall and ceiling.

•Strip 1/4" of insulation from each set of wires. Separate white and white/black wires sufficiently to connect to the opener terminal screws: white to 2 and white/black to 3.

•Plug in the opener. Make sure the Lock Feature is off. Green indicator lights in both the sending and receiving eyes will glow steadily if wiring connections and alignment are correct.

If the indicator light is offin the receiving eye (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 green indicator light glows with a steady lighL

•When indicator lights are glowing steadily in both units, tighten the wing nut in the receiving eye unit.
