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 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.
They will turn off automatically after 4-1/2 minutes or
provide constant light when the Light feature is activated.
Lights will also turn on when someone walks through the
open garage door. Bulb size is 100 watts maximum.

Operation of Your Opener
WARNING
Lighted Door Control Button: Press 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.
Operation of the Door Control
(see page 21)
(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 button.
