Operation
Features
Your garage door opener is equipped with features to provide you with greater control over your garage door
operation.
ALERT2CLOSE
The Alert2Close feature provides a visual and an audible alert that an unattended door is closing.
TIMER-TO-CLOSE (TTC)*
The TTC feature automatically closes the door after a specified time period that can be adjusted using a TTC
enabled control panel (Models 881LMW or 880LMW). Prior to and during the door closing the garage door
opener lights will flash and the garage door opener will beep.
MYQ
myQ® allows you to control your garage door opener from your mobile device from anywhere. myQ® technology
uses a 900 Mhz signal to provide two way communication between the garage door opener and myQ® enabled
accessories.
The garage door opener has an internal gateway that allows the garage door opener to communicate directly
with a home Wi-Fi® network and access your myQ® account.

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 control panel or keyless entry until the door is fully closed.
The safety reversing sensors do not affect the opening cycle. For more information see page 24.
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 Integrated LED lights; as the Integrated LED lights turn 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 Integrated LED lights 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.
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
Integrated LED lights on your garage door opener, see page 38.
USING YOUR GARAGE DOOR OPENER
When the door is closed and the garage door opener is activated the door will open. If the door makes contact
with an obstruction while opening, the door will stop, opener beeps and lights flash 5 times. 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
makes contact with an obstruction while closing, the door will reverse, opener beeps and lights flash 5 times. 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 control panel 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.
BATTERY BACKUP*
The battery backup system allows access in and out of your garage, even when the power is out. When the
garage door opener is operating on battery power, the garage door opener will run slower, the light will not
function, the Battery Status LED will glow solid orange, and a beep will sound approximately every 2 seconds.
CAMERA*
Live steam what is happening in your garage with your garage door opener's built-in camera. Just connect your
opener to Wi-Fi and set up an account with the myQ
AUTOMATIC GARAGE DOOR LOCK*
Garage door opener models featuring the Security Shield are compatible with the LiftMaster Automatic Garage
Door Lock (Model 841LM).
