This door control contains a
motion detector that will
automatically turn on the light
when it detects a person
entering the garage. This feature can be easily
turned off for extended work light use.
Light feature
Press the Light button to turn the opener light on or
off. It will not control the opener lights when the door
is in motion. If you turn it on and then activate the
opener, the light will remain on for 4-1/2 minutes.
Press again to turn it off sooner. The 4-1/2 minute
interval can be changed to 1-1/2, 2-1/2, or 3-1/2
minutes as follows: Press and hold the Lock button
until the light blinks (about 10 seconds). A single blink
indicates that the timer is reset to 1-1/2 minutes.
Repeat the procedure and the light will blink twice,
resetting the timer to 2-1/2 minutes. Repeat again for
a 3-1/2 minute interval, etc., up to a maximum of four
blinks and 4-1/2 minutes.
When using the opener lights as working lights, we
recommend that you first disable the motion sensor.
See Automatic Light Feature, below.
Automatic Light Feature: The opener light will turn
on automatically when a person enters the garage.
When a person walks in front of the door control, the
light will come on for five minutes, then shut off. This
feature works by detecting body heat and may not
work in temperatures around 100˚F.
To disable this feature, slide the Detector Switch on
the right side of the door control down (off).
We recommend that you disable the motion sensor
when using the opener lights as working lights.
Otherwise, they will turn off automatically if you are
working beyond the sensors range.

hand-held remote controls. However, the door will
open and close from the Door Control, the Outdoor
Key Switch and the Keyless Entry Accessories.

seconds. The push button light will flash as long as
the Lock feature is on.
To turn off, press and hold the Lock button again for
2 seconds. The push button light will stop flashing.
The Lock feature will also turn off whenever the

WARNING
To prevent possible SERIOUS INJURY or DEATH from a
falling garage door:
CAUTION
• If possible, use emergency release handle to
disengage trolley ONLY when garage door is CLOSED.
Weak or broken springs or unbalanced door could
result in an open door falling rapidly and/or
unexpectedly.
• NEVER use emergency release handle unless garage
doorway is clear of persons and obstructions.
• NEVER use handle to pull door open or closed. If rope
knot becomes untied, you could fall.
DISCONNECT THE TROLLEY:
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 automatically,
and the door can be raised
and lowered manually as
often as necessary.
TO RE-CONNECT THE
TROLLEY:
Pull the emergency
release handle toward the
opener at an angle so that
the trolley release arm is
horizontal. The trolley will
reconnect on the next UP
or DOWN operation, either
manually or by using the
door control or remote.
