Using Your Garage Door Opener
Your Security.I-e 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.I-e remote controls and one
Security.I-e KeylessEntry System. If you purchase a new remote,
or if you wish to deactivate any remote, follow the instructions in
the Programming section.
Activateyour 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 (SeeAccessories): If provided with your
garage door opener, it must be programmed before use. See
Programming.
Whenthe openeris activated (with the safety reversing
sensorcorrectlyinstalled 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 or Keyless Entry, if you activate them until down
travel is complete. If you releasethem too soon, the door will
reverse.
The openerlights 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
