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. 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.
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
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.
