during the closing

This door control
contains a motion

will automatically turn
on the light when it
detects a person entering the garage.
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.
Lock feature
Designed to prevent operation of the door from
hand-held remote controls. However, the door
will open and close from the Door Control, the Outdoor
Key Switch and the Keyless Entry Accessories.

To turn off, press and hold the Lock button again for

Motion Sensing (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.
To disable this feature, push the motion sensing
button on the side of the door control.
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.
