Using Your Garage Door Opener
Your Security-P R_ 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 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 light 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 75 watts maximum.
