THE PROTECTOR SYSTEM ® (SAFETY REVERSING SENSORS)
When properly connected and aligned, the safety reversing sensors will detect an obstruction in the path
of the infrared beam. If an obstruction breaks the infrared beam while the door is closing, the door will
stop and reverse to full open position, and the opener lights will flash 10 times. If the door is fully open,
and the safety reversing sensors are not installed, or are misaligned, the door will not close from a
remote control. However, you can close the door if you hold the button on the door control or keyless
entry until the door is fully closed. The safety reversing sensors do not effect the opening cycle.

LIGHTS
The garage door opener light bulb(s) will turn on when the opener is initially plugged in; power is
restored after interruption, or when the garage door opener is activated. The lights will turn off
automatically after 4-1/2 minutes. An incandescent A19 light bulb (60 watt maximum) or for maximum
energy efficiency a 23W (100W equivalent) compact fluorescent light (CFL) bulb may be used. NOTE:
Do not use halogen, short neck, or specialty light bulbs as these may overheat the unit. The use of LED
bulbs may reduce the operating range or performance of your remote controls.
Light Feature
The garage door opener is equipped with an added feature; the lights will turn on when someone enters
through the open garage door and the safety reversing sensor infrared beam is broken.
