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 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 Outdoor Key
Switch, 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. Bulb
size is A19. Bulb power is 75 watts maximum.
