Your Security ✚ ® garage door 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
garage door 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 garage door 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 garage door opener is activated
(with the safety reversing sensor correctly
installed and aligned).
• If open, the door will close. If closed, it
will open.
• If closing, the door will reverse.
• If opening, the door will stop.
• If the door has been stopped in a partially
open position, it will close.
• If obstructed while closing, the door will
reverse. If the obstruction interrupts the
sensor beam, the garage door opener
lights will blink for fi ve seconds.
• If obstructed while opening, the door
will stop.
• 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 garage door opener lights will turn on
when the garage door opener is activated.
They will turn off automatically after 4-1/2
minutes or provide constant light when the
Light feature on the Smart Control Panel
®
is activated. Bulb size is A19. Bulb power is
