Operation
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 specifi ed time period that can be
adjusted using a TTC enabled door control (Models 881LM or 880LM). Prior to and during
the door closing the garage door opener lights will fl ash and the garage door opener will
beep.
®
MyQ
MyQ® technology uses a 900MHz signal to provide two-way communication between the
garage door opener and MyQ® enabled accessories. Your garage door opener is compatible
with up to 16 MyQ® accessories.
SECURITY✚ 2.0™ REMOTE CONTROLS AND DOOR CONTROLS
Your garage door opener has already been programmed at the factory to operate with your
remote control, which changes with each use, randomly accessing over 100 billion new
codes. Compatible with Security+ 2.0™ accessories.
NOTE: Older LiftMaster remote controls, door controls, and third party products are not
compatible.

MEMORY CAPACITY
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 fl ash
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.
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. 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 (75 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.
USING YOUR GARAGE DOOR OPENER
The garage door opener can be activated through a wall-mounted door control, remote
control, or wireless keyless entry. 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.

Operation
To Open the Door Manually
To prevent possible SERIOUS INJURY or DEATH from a falling garage door:
• If possible, use emergency release handle to disengage trolley ONLY when garage
door is CLOSED. Weak or broken springs or unbalanced door could result in an open
door falling rapidly and/or unexpectedly.
• NEVER use emergency release handle unless garage doorway is clear of persons and
obstructions.
• NEVER use handle to pull door open or closed. If rope knot becomes untied, you
could fall.
DISCONNECT THE TROLLEY
1 The door should be fully closed if possible.
2 Pull down on the emergency release handle.
RECONNECT THE TROLLEY
The lockout feature prevents the trolley from reconnecting
automatically.
1 Pull the emergency release handle down and back (toward
the opener). The door can then be raised and lowered
manually as often as necessary.
2 To disengage the lockout feature, pull the handle straight

Adjustment
Introduction
Without a properly installed safety
reversal system, persons (particularly
small children) could be SERIOUSLY
INJURED or KILLED by a closing
garage door.
• Incorrect adjustment of garage door
travel limits will interfere with proper
operation of safety reversal system.
• After ANY adjustments are made,
the safety reversal system MUST
be tested. Door MUST reverse on
contact with 1-1/2" (3.8 cm) high
object (or 2x4 laid fl at) on fl oor.
To prevent damage to vehicles, be
sure fully open door provides adequate
clearance.
Your garage door opener is designed with
electronic controls to make setup and
adjustments easy. The adjustments allow
you to program where the door will stop in
the open (UP) and close (DOWN) position.
The electronic controls sense the amount of
force required to open and close the door.
NOTE: If anything interferes with the door’s
upward travel it will stop. If anything
interferes with the door’s downward travel,
it will reverse.

Without a properly installed safety
reversal system, persons (particularly
small children) could be SERIOUSLY
INJURED or KILLED by a closing
garage door.
• Safety reversal system MUST be
tested every month.
• After ANY adjustments are made,
the safety reversal system MUST
be tested. Door MUST reverse on
contact with 1-1/2" high (3.8 cm)
object (or 2x4 laid fl at) on the fl oor.

the obstruction, increase the down travel
(refer to Adjustment Step 1).
Repeat the test. When the door reverses
upon contact with the 1-1/2 inch board,
remove the board and open/close the door 3
or 4 times to test the adjustment.
If the test continues to fail, call a trained
door systems technician.

If the garage door opener closes the
door when the safety reversing sensor is
obstructed (and the sensors are no more
than 6 inches [15 cm] above the fl oor), call
for a trained door systems technician.
Maintenance
EVERY MONTH
• Manually operate door. If it is unbalanced or binding, call a trained door systems
technician.
• Check to be sure door opens and closes fully. Adjust if necessary, see page 10.
• Test the safety reversal system. Adjust if necessary, see page 11.
EVERY YEAR
• Oil door rollers, bearings and hinges. The garage door opener does not require additional
lubrication. Do not grease the door tracks.
EVERY TWO TO THREE YEARS
• Use a rag to wipe away the existing grease from the garage door opener rail. Reapply a
small layer of white lithium grease to the top and underside of the rail surface where the
trolley slides.
The Remote Control Battery
To prevent possible SERIOUS INJURY or DEATH:
• NEVER allow small children near batteries.
• If battery is swallowed, immediately notify doctor.
To reduce risk of fi re, explosion or chemical burn:
• Replace ONLY with 3V CR2032 coin batteries.
• DO NOT recharge, disassemble, heat above 212°F (100°C) or incinerate.
The lithium batteries should produce power
for up to 3 years. If the battery is low, the
remote control’s LED will not fl ash when the
button is pressed. To replace battery, pry
open the case fi rst in the middle (1), then at
each side (2 and 3) with the visor clip. Insert
battery positive side up.
Replace the batteries with only 3V CR2032
coin cell batteries. Dispose of old batteries
properly.
