Limit and Force Adjustments
Weather conditions may cause

readjustments, particularly during
the fi rst year of operation.
Pages 21 and 22 refer to the limit
and force adjustments. Only a
screwdriver is required. Follow the
instructions carefully.
Repeat the safety reverse test (page 23) after any
adjustment of limits or forces.

USING THE WALL-MOUNTED DOOR CONTROL
The Multi-Function Door Control
Press the push bar/push button
to open or close the door. Press

the closing cycle or to stop the
door while it’s opening.
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

be changed to 1-1/2, 2-1/2, or 3-1/2 minutes as follows:
1. 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.
2. Repeat the procedure and the light will blink twice,
resetting the timer to 2-1/2 minutes.
3. Repeat again for a 3-1/2 minute interval, etc., up to a
maximum of four blinks and 4-1/2 minutes.
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 Outside Keylock and the
Keyless Entry Accessories.
To activate, press and hold the Lock button for 2 seconds.
The push bar 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 bar light will stop fl ashing. The Lock
feature will also turn off whenever the “Learn” button on
the motor unit panel is activated.
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.

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
