OPERATION
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 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.
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 100 watts maximum.
Security✚ ® light feature: Lights will also turn on when someone
walks through the open garage door. With a Smart Control
Panel
® , this feature may be turned off as follows: With the opener
lights off, press and hold the light button for 10 seconds, until the
light goes on, then off again. To restore this feature, start with the
opener lights on, then press and hold the light button for 10
seconds until the light goes off, then on again.
