To Open the Door Manually
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.
Using the Wall-Mounted Door Control
THE MOTION DETECTING DOOR CONTROL
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.
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 fi rst 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 fi ve minutes, then shut off. This feature works
by detecting body heat and may not work in temperatures
around 100° F (37.7° C).
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.
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.
The push button light will fl ash 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 fl ashing. The Lock
feature will also turn off whenever the “learn” button on
the motor unit panel is activated.
Additional feature when used with the
3-Button hand-held remote

button that you want to control the light.
2. Press and hold the Light button on the door control.
