Control Console
THE LCD MOTION DETECTING CONTROL CONSOLE
Press the push bar to
open or close the
door. Press again to
reverse the door
during the closing
cycle or to stop the

opening.
This door control
contains a motion
sensing detector that
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 activate, press and hold the Lock button for 2 seconds.
To turn off, press and hold the Lock button again for
2 seconds. The Lock feature will also turn off whenever the
“learn” button on the motor unit panel is activated.
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.
