OPERATION

EMERGENCY DOOR RELEASE

To prevent possible SERIOUS INJURY or DEATH from a falling door:

• If possible, use emergency release handle to disengage door ONLY when 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 the doorway is clear of persons and obstructions.

ADJUSTMENT STEP 6

To Open the Door Manually

Disengage door lock before proceeding. The door should be fully closed if possible. Pull down on the emergency release handle until a click noise is

heard from the unit and lift the door manually. To reconnect the door to the operator, pull down the emergency release handle straight down a second

time until a click noise is heard from the unit. The door will reconnect on the next UP or DOWN operation.

Test the emergency release:

• Make sure the door is closed.

• Pull the emergency release handle. The door should then be able to be opened manually.

• Return the door to the closed position.

• Pull the emergency handle a second time.

• Reconnect the door to the operator.

Using Your Door Opener

Your operator and hand-held remote control have been factory-set to a

matching code which changes with each use, randomly accessing over

100 billion new codes. Your operator will operate with up to 64 remote

controls and one Keyless Entry System. If you purchase a new remote,

or if you wish to deactivate any remote, follow the instructions in the

Programming section.

Activate your operator with any of the following:

• The hand-held Remote Control: Hold top middle button down until the

door starts to move.

• The wireless wall control 128LM press and hold the large round button

down until the door starts to move.

• The Keyless Entry (See Accessories): If provided with your door

operator, it must be programmed before use. See Programming.

When the operator is activated (with the safety reversing sensor

correctly installed and aligned)

1. If open, the door will close. If closed, it will open.

2. If closing, the door will stop.

3. If opening, the door will stop.

4. If the door has been stopped in a partially open position, it will close.

5. If obstructed while closing, the door will reverse. If the obstruction

interrupts the sensor beam, the operator wil click for five seconds.

6. If obstructed while opening, the door will stop.

7. If fully open, the door will not close when the beam is broken. The

sensor has no effect in the opening cycle.

If the sensor is not installed, or is misaligned, the door won't close from a

hand-held remote. However, you can close the door with the Door

Control, the Outside Keylock, or Keyless Entry, if you activate them until

down travel is complete. If you release them too soon, the door will

reverse.

Automatic Close Timer Function

Note: Requires the Chamberlain Protector System (IR-sensors) to be

installed. If Protector System (IR-sensors) is installed only to enable the

timer to close function (first time), install Sensors close to garage door

and wait for 5 minutes.

A Multi-function Door Control (78LM) is required to enable and disable

the auto-close function.

Enable: Push and hold lock button on the Multi-function Door Control

until the electric lock toggled twice. At the same time watch the LED light

in the center of the actuator button from the Multi-function Door Control.

1x blink 10 seconds Auto-Close

2x blink 45 seconds Auto-Close

3x blink 2 minutes Auto-Close

4x blink 3 minutes Auto-Close

5x blink OFF Auto-Close

Factory setting is OFF. Repeat the procedure until the Multi-function Door

Control shows the required number of blinks.
