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 w ith any of the follow ing:
• The hand-held Remote Control: Hold the large
push button down until the door starts to move.
• The wall-mounted Door Control: Ftold 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.
W hen the opener is activated (w ith 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.
Lights will also turn on when someone walks through
the open garage door.
They will turn off automatically after 4-1/2 minutes.
