CAUTION
WARNING
An unbalanced garage door might not reverse
when required and someone under the door
could be seriously injured or killed.
If your garage door binds, sticks or is out of
balance, call for professional garage door
service. Garage doors, door springs, cables,
pulleys, brackets and their hardware, are
under extreme tension and can cause serious
injury or death. Do not try to loosen, move or
adjust them yourself!
Ropes left on a garage door could cause
someone to become entangled and killed.
Remove all ropes connected to the door before
installing and operating the opener.
To avoid damage to the garage door and
opener, disable locks before installing and
operating the opener. Use a wood screw or nail
to hold locks in the "open" (unlocked) position.
Operation at other than 120V 60 Hz will cause
opener malfunction and damage.
Before you begin, complete the following test to
make sure your door is balanced, and is not
sticking or binding:
• Lift the door about halfway as shown. Release the
door. It should stay in place, supported entirely by
its springs.
• Raise and lower the door to see if there is any
binding or sticking.
Identify the type and height of your door and any
special conditions that exist and any additional
materials that may be required by referring to page 4.

Installation Step 1
WARNING
Determine Header Bracket Location
If the header bracket is not rigidly fastened to
a structural support on the header wall or
ceiling, the safety reverse system may not
work properly (see page 26). The door might
not reverse when required, and could cause
serious injury or death.
The garage door springs, cables, pulleys,
brackets and their hardware are under extreme
tension. Do not attempt to loosen, move or
adjust them yourself. Serious personal injury
or death could result. Call for garage door
service.
Installation procedures vary according to garage
door types. Follow the instructions which apply to
your door.

WARNING
Install the Multi-Function
Door Control Panel
Children operating or playing with a garage
door opener can injure themselves or others.
The garage door could close and cause
serious injury or death.
Install the Door Control (or any additional push
buttons) out of the reach of children and away
from all moving parts of the door and door
hardware, but where the garage door is visible.
Do not allow children to operate the push
button(s) or the remote control transmitter(s).
A moving garage door could injure someone
under it. Activate the opener only when the
door is properly adjusted, you can see it clearly,
and there are no obstructions to door travel.
• Strip 1/4" of insulation from one end of the bell
wire; connect the wire to the two screw terminals
on the back of the Door Control by color:
white to 2 and white/red to 1.
• Locate the Door Control within sight of the
door at a minimum height of 5 feet where small
children cannot reach, and away from all
moving parts of the door and door hardware.
Fasten the Multi-Function Door Control Panel
securely with 6ABx1" screws. If installing into
drywall, drill 5/32" holes and use the anchors
provided.
• Run the bell wire up the wall and across the ceiling
to the opener. Use insulated staples to secure the
wire in several places. Be careful not to pierce the
wire with a staple, thereby resulting in a short.
• Receiver terminals and the antenna are located on
the right side panel of the opener. Position the
antenna wire as shown.
• Then connect the bell wire to the opener terminal
screws: white to 2 and white/red to 1.
• Remember to affix the User Safety Instruction
label to the wall near the Door Control, and the
Maintenance Instruction label in a prominent
location on the inside of the garage door.
If the label adhesive will not adhere to your garage
wall surface (or becomes loose with time) use tacks
to secure the label alongside the Door Control.
Page 28 explains how to operate the opener using
the lighted push bar and the Lock & Light features
available on the Multi-Function Door Control Panel.
Do NOT connect the power and operate the
opener at this time. The trolley will travel to the
full open position but will not return to the
close position until the sensor beam is
connected and properly aligned.

Information you'll need before you begin the installation of the safety reversing sensor.
The safety reversing sensor must be connected
and aligned correctly before the garage door
opener will move in the down direction. This is a
required safety device and cannot be disabled.
WARNING
Without a properly working safety reversing
sensor, persons (particularly children) could
be injured or killed by a closing garage door.
Read and follow all instructions.
To protect small children, install the safety
reversing sensor so that the beam will be no
higher than 4"-6" above the garage floor.
Disconnect power to the garage door opener
before installing the safety reversing sensor.
Installation procedures are the same for sectional
and one-piece doors.

Protection Area
Figure 1: Facing the door from inside the garage
The brackets must be securely fastened to a solid
surface such as the studs on either side of the door,
or add a piece of wood at each location if installing in
masonry construction.
The invisible light beam path must be unobstructed.
No part of the garage door (or door tracks, springs,
hinges, rollers or other hardware) can interrupt the
beam while the door is closing. If it does, use a piece
of wood to build out each sensor mounting location to
the minimum depth required for light beam clearance.
Be sure power to the opener is disconnected.
The sending eye transmits an invisible light beam to
the receiving eye.The units can be installed on
either side of the garage door as long as the sun
never shines directly into the receiving eye lens.
Look at the label on the connector end of each case
to identify the sensors.
The brackets must be connected and fastened so
that the sending and receiving eyes face each other
as shown in Figure 1.
If an obstruction breaks the light beam while the
garage door is closing, the door will stop and
reverse to full open position; and the opener lights
will flash for 5 seconds.

• Strip 1/4" of insulation from each set of wires.
Separate white and white/black wires sufficiently to
connect to the opener terminal screws: white to 2
and white/black to 3.
• Plug in the opener. Make sure the Lock Feature is
off. Green indicator lights in both the sending and
receiving eyes will glow steadily if wiring
connections and alignment are correct.
If the indicator light is off in the receiving eye (and
the invisible light beam path is not obstructed),
alignment is required.
• Loosen the receiving eye wing nut to allow slight
rotation of unit. Adjust sensor vertically and/or
horizontally until the green indicator light glows
with a steady light.
• When indicator lights are glowing steadily in both
units, tighten the wing nut in the receiving eye unit.
Trouble Shooting
1. If the sending eye indicator light does not glow
steadily after installation, check for:
• Electric power to the opener.
• A short in the white or white/black wires. These
can occur under staples or at screw terminal
connections.
• Incorrect wiring between sensors and opener.
• An open wire (wire break).
• Lock switch on Multi-Function Door Control Panel
is on. Turn it off.
2. If the sending eye indicator light glows steadily but
the receiving eye indicator light doesn't:
• Check alignment.
• Check for an open wire to the receiving eye.

CAUTION
Fasten Door Bracket
To prevent damage to steel, aluminum,
fiberglass or glass panel doors, always
reinforce the inside of the door both vertically
and horizontally with angle iron.
Follow instructions which apply to your door type
as illustrated below or on page 21.
A horizontal brace should be long enough to be secured to 2 vertical supports. A vertical brace should
cover the height of the top panel.
The illustration shows one piece of angle iron as the horizontal brace. For the vertical brace, 2 pieces of
angle iron are used to create a "U"-shaped support. The best solution is to check with your garage door
manufacturer for an opener installation, door reinforcement kit.

Adjustment Procedures for One-Piece Doors
Open Door Adjustment:
Decrease UP limit
• Turn the UP limit adjustment screw counterclockwise 5-1/2 turns.
• Press the Door Control push bar. The trolley will
travel to the fully open position.
• Manually raise the door to the open position
(parallel to the floor), and lift the door arm to the
trolley. The arm should touch the trolley just in
back of the door arm connector hole. Refer to the
fully open trolley/door arm positions in the
illustration. If the arm does not extend far enough,
adjust the limit further. One full turn equals 2" of
trolley travel.
Closed Door Adjustment:
Decrease DOWN limit
• Turn the DOWN limit adjustment screw clockwise 5
complete turns.
• Press the Door Control push bar. The trolley will
travel to the fully closed position.
• Manually close the door and lift the door arm to the
trolley. The arm should touch the trolley just ahead
of the door arm connector hole. Refer to the fully
closed trolley/door arm positions in the illustration. If
the arm is behind the connector hole, adjust the limit
further. One full turn equals 2" of trolley travel.
Connect the door arm to the trolley.
• Close the door and join the curved arm to the connector hole in the trolley with the remaining clevis pin.It may be
necessary to lift the door slightly to make the connection.
• Secure with a ring fastener.
• Run the opener through a complete travel cycle. If the door has a slight "backward" slant in full open position as
shown in the illustration, decrease the UP limit until the door is parallel to the floor.

Adjustment Section: Pages 24 – 26
Adjustment Step 1
WARNING
Adjust the UP and DOWN Limits
Improper adjustment of the travel limits will
interfere with the proper operation of the safety
reverse system. The door might not reverse
when required and could seriously injure or kill
someone under it. Test the safety reverse
system following all adjustments to the travel
limits. See page 26.
Do not make any limit adjustments until the
safety reversing sensors are completely
installed.
Limit adjustment settings regulate the points at
which the door will stop when moving up or down.
The door will stop in the up direction if anything
interferes with door travel. The door will reverse in
the down direction if anything interferes with the
door travel (including binding or unbalanced doors).
To operate the opener, press the Door Control push
bar. Run the opener through a complete travel
cycle.
• Does the door open and close completely?
• Does the door stay closed and not reverse
unintentionally when fully closed?
If your door passes both of these tests, no limit
adjustments are necessary unless the reversing test
fails (See page 26).
Adjustment procedures are outlined below. Run
the opener through a complete travel cycle after
each adjustment.
Repeated operation of the opener during
adjustment procedures may cause the motor to
overheat and shut off. Simply wait 15 minutes
and try again.
Read the procedures carefully before continuing on
to Adjustment Step 2. Use a screwdriver to make
limit adjustments.

How and When to Adjust the Limits
If the door does not open completely
but opens at least five feet
Increase up travel. Turn the UP limit adjustment
screw clockwise. One turn equals 2" of travel.
If door does not open at least 5 feet: Adjust the
UP (open) force as explained in Adjustment Step 2.
If the opener reverses in fully closed position
Decrease down travel. Turn the DOWN limit
adjustment screw clockwise. One turn equals 2" of
travel.
If the door reverses when closing and
there is no visible interference to travel cycle
If the opener lights are flashing, the Safety Reversing
Sensor is obstructed. Remove the obstruction.
Test the door for binding: Pull the manual release
handle. Manually open and close the door. If the door
is binding, call for garage door service. If the door is
not binding or unbalanced, adjust the DOWN (close)
force. See Adjustment Step 2.
If the door does not close completely
Increase down travel. Turn the DOWN limit
adjustment screw counterclockwise. One turn
equals 2" of travel.
If door still won't close completely, try lengthening
the door arm. (See page 22.)
If you have adjusted the door arm to the maximum
length and the door still will not close completely,
lower the header bracket. See Installation Step 1,
pages 8 and 9.
24
Adjustment Step 2
WARNING
Adjust the Force
Too much force on the door will interfere with
the proper operation of the safety reverse
system. The door might not reverse properly
when required and could seriously injure or
kill someone under it. Do not increase the
force beyond the minimum amount required to
close the door. Do not use the force
adjustments to compensate for a binding or
sticking garage door. Test the safety reverse
system following all adjustments to force
levels. See page 26.
Force adjustment controls are located on the right
side panel of the opener. Force adjustment settings
regulate the amount of power required to open and
close the door.
The door will stop in the up direction if anything
interferes with its travel. The door will reverse in the
down direction if anything interferes with its travel
(including binding or unbalanced doors).
If the forces are set too light, door travel may be
interrupted by nuisance reversals in the down
direction and stops in the up direction. Weather
conditions can affect the door movement, so
occasional adjustment may be needed.
The maximum force adjustment range is 260
degrees, about 3/4 of a complete turn. Do not force
controls beyond that point. Turn force adjustment
controls with a screwdriver.

How and When to Adjust the Forces
If the door doesn't open at least 5 feet
Increase UP (Open) force by turning the control
clockwise. Make 10 degree turn adjustments until
door opens completely. Re-adjust the UP limit if
necessary. After each adjustment, run the opener
through a complete travel cycle.
Test the DOWN (close) force
Grasp the door bottom when the door is about
halfway through DOWN (close) travel. The door
should reverse. (Reversal halfway through down
travel does not guarantee reversal on a one-inch
obstruction. See page 26.) If the door is hard to
hold or doesn't reverse, decrease the DOWN (close)
force by turning the control counterclockwise.
Make 10 degree turn adjustments until the door
reverses normally. After each adjustment, run the
opener through a complete cycle.
If the door reverses during the down (close) cycle
and the opener lights aren't flashing
Increase DOWN (close) force by turning the control
clockwise. Make 10 degree turn adjustments until the
door completes a close cycle. After each adjustment,
run the opener through a complete travel cycle. Do
not increase the force beyond the minimum
amount required to close the door.
Test the UP (open) force
Grasp the door bottom when the door is about
halfway through UP (open) travel. The door should
stop. If the door is hard to hold or doesn't stop,
decrease UP (open) force by turning the control
counterclockwise. Make 10 degree turn adjustments
until the door stops easily. After each adjustment,
run the opener through a complete travel cycle.

WARNING
Test the Safety Reverse System
Failure to test and adjust the safety reverse
system may result in serious injury or death
from a closing garage door. Repeat this test
once a month and adjust as needed.
Test:
• Place a 2x4 laid flat on the floor, centered under
the garage door.
• Operate the door in the down direction. The door
must reverse on striking the obstruction.

Receiver and Remote Control Programming
NOTICE: To comply with FCC/IC rules, adjustment or modifications of
this receiver and/or transmitter are prohibited, except for changing the
code setting or replacing the battery. THERE ARE NO OTHER USER
SERVICEABLE PARTS.
WARNING
Children operating or playing with a garage
door opener can injure themselves or others.
The garage door could close and cause
serious injury or death. Do not allow children
to operate the Door Control or remote control
transmitter(s).
A moving garage door could injure or kill
someone under it. Activate the opener only
when you can see the door clearly, it is free of
obstructions, and is properly adjusted.
Your garage door opener receiver and remote control
transmitter have been set at the factory to a matching
code. The door will activate when the remote control
push button is pressed.
Your "Smart" garage door opener will operate with:
• up to four "Smart" remote control transmitters
(with green indicator lights),
• a Keyless Entry System, and
• code switch transmitters with red indicator lights.
Below are instructions for programming your opener
to match any additional remotes you may purchase.
See available accessories on page 34.
To Add A Remote
1. Press and hold the remote push button. See
Figure 1.
2. Then press and release the "Smart" button on the
right side of the opener in Figure 2. The opener
lights will flash once.
3. Release the remote push button.
Now the opener will operate when the remote control
push button is pressed.
If you release the remote control push button
before the opener lights flash, the opener will not
accept the code.
Figure 1
To Erase All Remote Control Codes
• Press and hold the "Smart" button on the opener
panel until the indicator light turns off (about 6
seconds). All the codes the opener has learned
will be erased.
• To reprogram, repeat Steps 1 - 3 for each remote
control in use.

Having a Problem?
Situation
Probable Cause & Solution
The opener doesn't
operate from either
the Door Control or
the remote control:
1. Does the opener have electric power? Plug a lamp into the outlet. If it doesn't light,
check the fuse box or the circuit breaker. (Some outlets are controlled by a wall switch.)
2. Have you disabled all door locks? Review installation instruction warnings on page 7.
3. Is there a build-up of ice or snow under the door? The door may be frozen to the
ground. Remove any restriction.
4. The garage door spring may be broken. Have it replaced.
5. Repeated operation may have tripped the overload protector in the motor. Wait 15
minutes. Try again.
Opener operates from 1. Is the door control lit? If not, remove the bell wire from the opener terminals. Short the
the remote, but not
red and white terminals by touching both terminals at the same time with a piece of
from Door Control:
wire. If the opener runs, check for a faulty wire connection at the door control, a short
under the staples, or a broken wire.
2. Are the wiring connections correct? Review Step 6, page 14.
The door operates
from the Door
Control, but not from
the remote control:
1. If your model has the Lock feature, turn it off.
2. Is the wall push button flashing? Your opener needs to re-learn a remote control
code. Refer to instructions on the opener panel.
3. Does the battery test light glow when the remote control push button is pressed? If
not, replace the battery.
4. Program the receiver to match the remote control code.
5. Repeat the receiver programming procedure with all remote controls.
The remote control
has short range:
1. Check the battery test light. If the light is dim, replace the battery.
2. Change the location of the remote control in your car.
3. Check to be sure the antenna on the side or back panel of opener extends fully
downward.
4. Some installations may have shorter range due to a metal door, foil backed insulation,
or metal garage siding.
Opener noise is
disturbing in living
quarters of home:
If operational noise is a problem because of proximity of the opener to the living
quarters, the Vibration Isolator Kit 41A3263 can be installed. This kit was designed to
minimize vibration to the house and is easy to install.
The garage door
opens and closes
by itself:
1. Be sure that all remote control push buttons and battery indicator lights are off.
2. Remove the bell wire from the door control terminals and operate from the remote
only. If this solves the problem, the door control is faulty (replace), or there is an
intermittent short on the wire between the door control and the opener.
The door doesn't
open completely:
1. If the door has been working properly but now doesn't open all the way, increase the
up force. See page 25.
2. Is something obstructing the door? Remove the obstruction or repair the door.
3. If door opens at least 5 feet, the travel limits may need to be increased. One turn
equals 2 inches of travel. See page 24.
Repeat the safety reverse test after the adjustment is complete.
The door stops but
doesn't close
completely:
Review the travel limits adjustment procedures on page 24.
Repeat the safety reverse test after any adjustment of door arm length, close
force or down limit.
30
Having a Problem? (continued)
Situation
Probable Cause & Solution
The door opens but
won't close:
1. If the opener lights blink, check the safety reversing sensor. See page 19.
2. If the opener lights do not blink and it is a new installation, check the down force.
See Adjustment Step 2, page 25. For an existing installation, see below.
Repeat the safety reverse test after the adjustment is complete.
The door reverses for
no apparent reason
and opener lights
don't blink:
1. Is something obstructing the door? Pull the manual release handle. Operate the door
manually. If it is unbalanced or binding, call for professional garage door service.
2. Clear any ice or snow from the garage floor area where the door closes.
3. Review the force adjustment procedures on page 25.
4. If door reverses in the fully closed position, decrease the travel limits (page 24).
Repeat safety reverse test after adjustments to force or travel limits. The need
for occasional adjustment of the force and limit settings is normal. Weather
conditions in particular can affect door travel.
The door reverses for
no apparent reason
and opener lights
blink for 5 seconds
after reversing:
Check the safety reversing sensor. Remove any obstruction or align the receiving eye.
See page 19.
The opener lights:
. . . don't turn on:
Replace the light bulbs (75 watts maximum). Use a standard neck garage door opener
bulb if regular bulb burns out.
. . . don't turn off:
Is the Light feature on? Turn it off.
The opener strains or
maximum force is
needed to operate
door:
The door may be out of balance or the springs are broken. Close the door and use the
manual release to disconnect the trolley. Open and close the door manually. A properly
balanced door will stay in any point of travel while being supported entirely by its
springs. If it does not, disconnect the opener and call a professional garage door
serviceman. Do not increase the force to operate the opener.
The opener motor
hums briefly, then
won't work:
1. The garage door springs are broken. See above.
2. If the problem occurs on the first operation of the opener, door may be locked.
Disable the door lock. If the belt was removed and reinstalled, the motor may be out
of phase. Remove the belt; cycle the motor to the down position. Observe the drive
sprocket. When it turns in a clockwise direction and stops in the down position,
reinstall the belt.
Repeat the safety reverse test after the adjustment is complete.
The opener won't
operate due to
power failure:
1. Use the manual release to disconnect the trolley. The door can be opened and
closed manually. When the power is restored, press the Door Control push bar and
trolley will automatically reconnect (unless trolley is in lockout position.) See page 28.
2. The Outside Quick Release accessory (for use on garages with no service door)
disconnects the trolley from outside the garage in case of power failure.
