OPERATION

Door Control Push Bar:

Press to open or close the door. Press

again to reverse the door during the closing cycle, or to stop the
door while it is opening.

Light Feature:

Press the Light button to switch the opener light

on or off. When the door is opened or closed, the light will remain
on for 4-1/2 minutes. Press the Light button to turn it off sooner.
The Light button will not control the opener light when the door is
in motion. When using the opener lights as working lights, we
recommend that you first disable the motion sensor. See

Automatic Light Override Feature,

below.

When used with openers manufactured after December 1, 1999,
(check the date on the opener panel) 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.

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 opener light will come on for
five minutes, then shut off. This feature works by detecting body
heat. It is more sensitive in front of the door control than at its
sides, and works better as a person moves closer. It may not
work in temperatures around 37  C. 
To disable this feature, slide the Detector Switch on the right side
of the door control down (off). 

Special note for older garage door openers:

If this door control is

installed on an opener manufactured from January 1, 1995 to
December 1, 1999, the following difference may apply: If the light
is on when the opener is actuated, the light may go off for a
moment, then turn on again as the detector senses you.

Automatic Light Override Feature: 

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 sensor’s range. Slide the Detector Switch
on the right side of the door control down (off), then press the
light button to control the lights.

Energy Saving Feature:

This door control senses the brightness

inside the garage, and will not turn the light on if it is already
bright enough. If the light sensor turns on the light when it is not
needed or does not turn it on when it is dark, the sensitivity can
be adjusted. Remove the push bar cover by gently prying off the
top edge with a coin or screwdriver. Underneath there is a dial
below the green light on the right side. Use a small screwdriver to
turn the dial by 1/4 turns: counterclockwise to make the light
come on, or clockwise to make the light go off. Replace the cover
by inserting top tabs and snapping into place.

Lock Feature:

Designed to prevent operation of the door from

portable remote controls. However, the door will open and close
from the Door Control push bar and from the Keylock and
Keyless Entry accessories.

To activate:

Press and hold the Lock button for 2 seconds. The

push button indicator light will flash as long as the lock is on.

To turn off:

Press and hold the Lock button again for 2 seconds.

The indicator light will stop flashing. Normal operation will
resume. The Lock feature will also turn off whenever the Smart
button on the opener end panel is activated.

This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
