Activate the opener with any of the following:

• The Remote Control Transmitter. Hold push button

down until the door starts to move.

• The Door Control. Hold push bar or button down until the

door starts to move.

• The Outside Keylock or Keyless Entry.

(See Accessories)

When the opener is activated with the safety reversing

sensor installed and correctly aligned:

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

2. If closing, the door will reverse.

3. If opening, the door will stop (allowing space for entry and

exit of pets and for fresh air).

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

will close.

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

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

7. The garage door will reverse in the closing cycle, and the

opener lights will blink for 5 seconds, when the invisible

beam is broken. 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 not aligned correctly, the door

won't close from any remote transmitter. You can close the door

with the Door Control, the Outside Keylock, or Keyless Entry,

however, if you activate them until down travel is complete. If

you release them too soon, the door will reverse.

Opener Lights will turn on under the following conditions:

When the opener is initially plugged in; when the power is

interrupted; when the opener is activated. It will turn off

automatically after 4-1/2 minutes or provide constant light

when the Light feature on the Multi-Function Door Control is

activated. Bulb size is 100 watts maximum.

Lights will also turn on when someone walks through the

open garage door. With a Multi-Function Door Control, this

feature may be turned off as follows: With the opener lights

off, press and hold the light button for 10 seconds, until the

light goes on and off again. To restore this feature, start with

the opener lights on, then press and hold the light button for

10 seconds.

Operation of Your Opener

WARNING

Lighted Door Control Button: Press to open or close the

door.

Lighted Push Bar – Door Control Panel: Press the white

square to open or close the door.

Press again to reverse the door during the closing cycle or

to stop the door while it's opening.

Light Feature – Door Control Panel: Press the Light

button to turn the opener light on or off. If you turn it on

and then activate the opener, the light will remain on for 4-

1/2 minutes. Press again to turn it off sooner. The Light

button will not control the opener lights when the door is in

motion.

The 4-1/2 minute interval can be changed to 1-1/2, 2-1/2,

or 3-1/2 minutes as follows: Press and hold the Lock button

until the light blinks (about 10 seconds). A single blink

indicates that the timer is reset to 1-1/2 minutes.

Repeat the procedure and the light will blink twice,

resetting the timer to 2-1/2 minutes. Repeat again for a 3-

1/2 minute interval, etc., up to a maximum of four blinks

and 4-1/2 minutes.

Lock Feature – Door Control Panel: Designed to prevent

operation of the door from portable remote controls.

However, the door will open and close from the Door

Control push bar, the Outside Keylock and the Keyless

Entry Accessories.

To Activate: Press and hold the Lock button for

2 seconds. The push bar light will flash as long as the

Lock feature is on.

To turn off: Press and hold the Lock button again for

2 seconds. The push bar light will stop flashing. The

Lock feature will also turn off whenever the “Smart”

button on the opener panel is activated.

Operation of the Door Controls: See additional programming features, next page.

To open the door manually:

The door should be fully

closed if possible. Pull down

on the manual release handle

(so that the trolley release

arm snaps into a vertical

position) and lift the door

manually. The lockout

feature prevents the trolley

from reconnecting auto-

matically, and the door can

be raised and lowered

manually as often as

necessary.

To reengage the trolley: Pull

the manual release handle

toward the opener at a 45

degree angle so that the

trolley release arm is

horizontal. The trolley will

reconnect on the next UP or

DOWN operation, either

manually or by pressing the

Door Control push bar or

button.
