Activate the opener with any of the following
devices:

1. The Remote Control Transmitter. Hold push

button down until the door starts to move.

2. The Door Control. Hold push bar down until the

door starts to move.

3. The Outside Keylock or Keyless Entry. 

(See Accessories)

When the Opener is Activated:

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

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 control
transmitter. You can close the door with the Door
Control, the Outside Keylock, or Keyless Entry,
however, if you press and 

hold the push bar until down

travel is complete. If you release the push bar too
soon, the door will 

reverse. 

The opener lights will 

blink for 5 seconds when the

safety reversing sensor causes the door to 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. Bulb size is 75 watts maximum.

The lockout feature
prevents the trolley from
reconnecting automatically.
Pull the manual release
handle down and back
(toward the opener). The
door can then be raised
and lowered manually as
often as necessary. To
disengage the lockout
feature, pull the manual
release handle straight
down. The trolley will
reconnect on the next UP
or DOWN operation.
