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 transmitter. 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.
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 is activated.
Bulb size is 100 watts maximum.

WARNING
To open the door
manually:
The door should be fully
closed if possible. Pull down
on the emergency release
handle (so that the trolley
release arm snaps into a
vertical position) and lift the
door manually. The lockout
feature prevents the trolley
from reconnecting auto-
matically, and the door can
be raised and lowered
manually as often as
necessary.
To reengage the trolley:
Pull the emergency release
handle toward the opener at
a 45° degree angle so that
the trolley release arm is
horizontal. The trolley will
reconnect on the next UP or
DOWN operation, either
manually or by pressing the
Door Control push button.
