Using Your Garage Door Opener

Your Security

®

 opener and hand-held remote control 

have been factory-set to a matching code which changes 
with each use, randomly accessing over 100 billion 
new codes. Your opener will operate with up to eight 
Security

®

 remote controls and one Security

®

 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 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 supplied 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 fi ve 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. 

The light will also turn on when someone walks through 
the open garage door. 

It will turn off automatically after 4-1/2 minutes. Bulb size 
is A19. Bulb power is 75 watts maximum.

hardware, ALL of which are under EXTREME tension, 
MUST be made by a trained door systems technician.
