Operation Of Your Opener - Craftsman 139.53663SRT Owner's Manual

Activate the opener with any of the following:
• The Remote Control: Hold push button down until the
door starts to move.
• The Door Control: Hold push bar or button down until
the door starts to move.
• The Outdoor Key Switch or Keyless Entry: (See
Accessories)
When the opener is activated with the safety reversing
sensor installed and correctly aligned:
1. If open, the door will close. If closed, the door will
open.
2. If closing, the door will reverse.
3. If opening, the door will stop (allowing space for entry
and exit of pets and for fresh air).
4. If the door has been stopped in a partially open position,
it will close.
5. If obstructed while closing, the door will reverse.
6. If obstructed while opening, the door will stop.
7. The garage door will reverse in the closing cycle when
the invisible beam is broken. 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 not aligned correctly, the
door won't close from any remote control. You can close
the door with the Door Control, the Outdoor Key Switch,
or Keyless Entry, however, if you activate them until down
travel is complete. If you release them too soon, the door
will reverse.
The opener lights will blink for 5 seconds when the safety
reversing sensor causes the door to reverse.
The Opener Lights will turn on under the following
conditions: When the opener is initially plugged in; when the
power is interrupted; 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 Premium
Control Console is activated. SECURITY models:
Lights will also turn on when someone walks through the
open garage door. Bulb size is 75 watts maximum.
Press the lighted push button to open or close the door.
Press again to reverse the door during the closing cycle
or to stop the door while it's opening.
Premium Console:
Light feature: Press the large round Light button. If the
opener light is off, it will turn on. If the opener light is
on, (even in the 4-1/2 minute automatic cycle) it will
turn off.
But if you use the Light button to turn the lights on and
then activate the opener, the lights will turn off after 4-
1/2 minutes.
The Light button will not control the opener lights when
the door is in motion.
