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 door control (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 or computer from
anywhere. myQ® technology uses a 900Mhz 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. 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. For more information see
page 19.
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.
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® App.
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. 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.
