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 opener with any of the following:

The hand-held Remote Control:

Hold the large

push button down until the door starts to move.

The wall-mounted Door Control:

Hold the push

button or bar down until the door starts to move.

The Keyless Entry (See Accessories):

If provided

with your garage door opener, it must be
programmed before use. See 

Programming.

When the opener 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 reverse.
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
opener lights will blink 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. 

The opener lights

will turn on under the following

conditions: when the opener is initially plugged in;
when power is restored after interruption; when the
opener is activated. 

They will turn off automatically after 4-1/2 minutes or
provide constant light when the Light feature on the
Motion Detecting Door Control is activated. Bulb size
is 100 watts maximum.

until the light goes on, then off again. To restore this
feature, start with the opener lights on, then press
