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 affect the opening cycle.

MEMORY CAPACITY
ENERGY CONSERVATION
For energy efficiency the garage door opener will enter sleep mode when the door is fully closed. The
sleep mode shuts the garage door opener down until activated. The sleep mode is sequenced with the
garage door opener light bulb; as the light bulb turns off the sensor LEDs will turn off and whenever the
garage door opener lights turn on the sensor LEDs will light. The garage door opener will not go into
the sleep mode until the garage door opener has completed 5 cycles upon power up.
LIGHTS
The garage door opener light bulbs 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 (100 watt maximum) or for maximum
®
energy efficiency a 26W (100W equivalent) compact fluorescent light (CFL) bulb may be used.
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. For
added control over the light bulbs on your garage door opener, see page 29.
USING YOUR GARAGE DOOR OPENER
The garage door opener can be activated through a wall-mounted door control, remote control,
wireless keyless entry or MyQ
activated the door will open. If the door senses an obstruction or is interrupted while opening the door
will stop. When the door is in any position other than closed and the garage door opener is activated
the door will close. If the garage door opener senses an obstruction while closing, the door will reverse.
If the obstruction interrupts the sensor beam the garage door opener lights will blink 10 times. 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 affect the opening cycle. The safety reversing sensor must
be connected and aligned correctly before the garage door opener will move in the down direction.
