ENERGY CONSERVATION
For energy effi ciency 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.
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 effi ciency a 26W (100W equivalent)
compact fl uorescent 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 7.
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 ® accessory. When the door is closed and
the garage door opener is 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.
