Preparing your garage door
Before you begin:
• Disable locks.
To prevent possible SERIOUS INJURY or DEATH:
• ALWAYS call a trained door systems technician if
garage door binds, sticks, or is out of balance. An
unbalanced garage door may NOT reverse when
required.
• NEVER try to loosen, move or adjust garage door,
door springs, cables, pulleys, brackets or their
hardware, ALL of which are under EXTREME
tension.
• Disable ALL locks and remove ALL ropes
connected to garage door BEFORE installing
and operating garage door opener to avoid
entanglement.
• Remove any ropes connected to garage door.
• Complete the following test to make sure your garage
door is balanced and is not sticking or binding:
1. Lift the door about halfway as shown. Release the
door. If balanced, it should stay in place, supported
entirely by its springs.
2. Raise and lower the door to see if there is any
binding or sticking.
If your door binds, sticks, or is out of balance, call a
trained door systems technician.
To prevent damage to garage door and opener:
• ALWAYS disable locks BEFORE installing and
operating the opener.
• ONLY operate garage door opener at 120V, 60 Hz
to avoid malfunction and damage.

Planning
Identify the type and height of your garage door. Survey
your garage area to see if any of the conditions below
apply to your installation. Additional materials may be
required. You may find it helpful to refer back to this page
and the accompanying illustrations as you proceed with
the installation of your opener.
• Look at the garage door where it meets the floor. Any
gap between the floor and the bottom of the door must
not exceed 1/4" (6 mm). Otherwise, the safety reversal
system may not work properly. See Adjustment Step 3.
Floor or door should be repaired.
Depending on your requirements, there are several
installation steps which may call for materials or hardware
not included in the carton.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horizontal and vertical reinforcement
is required (Installation Step 11).
• Installation Step 1 – Look at the wall or ceiling above
the garage door. The header bracket must be securely
fastened to structural supports.
• The opener should be installed above the center of the
door. If there is a torsion spring or center bearing plate
in the way of the header bracket, it may be installed
within 4 feet (1.22 m) to the left or right of the door
center. See Installation Steps 1 and 11.
• Installation Step 5 – Do you have a finished ceiling in
your garage? If so, a support bracket and additional
fastening hardware may be required.
• Installation Step 10 – Depending upon garage
construction, extension brackets or wood blocks may
be needed to install sensors.
• If your door is more than 7 feet (2.13 m) high, see rail
extension kits listed on Accessories page.
• Installation Step 10 – Alternate floor mounting of
the safety reversing sensor will require hardware not
provided.
• Do you have an access door in addition to the garage
door? If not, Model 7702CB Emergency Key Release is
required. See Accessories page.
SECTIONAL DOOR INSTALLATION
Horizontal and vertical reinforcement
is needed for lightweight garage
doors (fiberglass, steel, aluminum,
door with glass panels, etc.).

ONE-PIECE DOOR INSTALLATIONS
Without a properly working safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• The gap between the bottom of the garage door
and the floor MUST NOT exceed 1/4" (6 mm).
Otherwise, the safety reversal system may NOT
work properly.
• The floor or the garage door MUST be repaired to
eliminate the gap.
• Generally, a one-piece door does not require
reinforcement. If your door is lightweight, refer to the
information relating to sectional doors in Installation
Step 11.
• Depending on your door’s construction, you may need
additional mounting hardware for the door bracket
(Step 11).

ASSEMBLY STEP 1
Assemble the Rail & Install the Trolley
To prevent INJURY from pinching, keep hands and
fingers away from the joints while assembling the rail.
To avoid installation difficulties, do not run the garage
door opener until instructed to do so.
The front rail has a cut out “window” at the door end
(see illustration). The hole above this window is larger
on the top of the rail than on the bottom. A smaller hole
3-1/2" (8.9 cm) away is close to the rail edge. Rotate the
back rail so it has a similar hole close to the opposite
edge, about 4-3/4" (12 cm) from the far end.
3. Place the motor unit on packing material to protect
the cover, and rest the back end of the rail on top.
For convenience, put a support under the front end of
the rail.
4. As a temporary trolley stop, insert a screwdriver into
the hole 10" (25 cm) away from the front of the rail,
as shown.
1. Remove the straight door arm and hanging bracket
packaged inside the front rail and set aside for
Installation Step 5 and 12. NOTE: To prevent INJURY
while unpacking the rail carefully remove the straight
door arm stored within the rail section.
5. Check to be sure there are 4 plastic wear pads inside
the inner trolley. If they became loose during shipping,
check all packing material. Snap them back into
position as shown.
2. Align the rail sections on a flat surface as shown and
slide the tapered ends into the larger ones. Tabs along
the side will lock into place.
6. Slide the trolley assembly along the rail from the back
end to the screwdriver.

Electrical Requirements
To prevent possible SERIOUS INJURY or DEATH from
electrocution or fire:
• Be sure power is NOT connected to the opener,
and disconnect power to circuit BEFORE removing
cover to establish permanent wiring connection.
• Garage door installation and wiring MUST be in
compliance with ALL local electrical and building
codes.
• NEVER use an extension cord, 2-wire adapter, or
change plug in ANY way to make it fit outlet. Be
sure the opener is grounded.
To avoid installation difficulties, do not run the opener
at this time.
To reduce the risk of electric shock, your garage door
opener has a grounding type plug with a third grounding
pin. This plug will only fit into a grounding type outlet.
If the plug doesn't fit into the outlet you have, contact a
qualified electrician to install the proper outlet.

INSTALLATION STEP 10
Install The Protector System®
Be sure power is NOT connected to the garage door
opener BEFORE installing the safety reversing sensor.
To prevent SERIOUS INJURY or DEATH from a
closing garage door:
• Correctly connect and align the safety reversing
sensor. This required safety device MUST NOT be
disabled.
• Install the safety reversing sensor so beam is NO
HIGHER than 6" (15 cm) above garage floor.
The safety reversing sensor must be connected and
aligned correctly before the garage door opener will
move in the down direction.
IMPORTANT INFORMATION ABOUT THE SAFETY
REVERSING SENSOR
When properly connected and aligned, the sensor will
detect an obstacle in the path of its electronic beam. The
sending eye (with an amber indicator light) transmits an
invisible light beam to the receiving eye (with a green
indicator light). If an obstruction breaks the light beam
while the door is closing, the door will stop and reverse to
full open position, and the opener lights will flash 10 times.
If it is necessary to mount the units on the wall, the
brackets must be securely fastened to a solid surface such
as the wall framing. Extension brackets (see Accessories)
are available if needed. If installing in masonry
construction, add a piece of wood at each location to
avoid drilling extra holes in masonry if repositioning is
necessary.
The units must be installed inside the garage so that the
sending and receiving eyes face each other across the
door, no more than 6" (15 cm) above the floor. Either can
be installed on the left or right of the door as long as the
sun never shines directly into the receiving eye lens.
The invisible light beam path must be unobstructed. No
part of the garage door (or door tracks, springs, hinges,
rollers or other hardware) may interrupt the beam while
the door is closing.
The mounting brackets are designed to clip onto the track
of sectional garage doors without additional hardware.

• Plug in the opener. The indicator lights in both the
sending and receiving eyes will glow steadily if wiring
connections and alignment are correct.
1. If the sending eye indicator light does not glow steadily
after installation, check for:
The sending eye orange indicator light will glow regardless
of alignment or obstruction. If the green indicator light in
the receiving eye is off, dim, or flickering (and the invisible
light beam path is not obstructed), alignment is required.
• Electric power to the opener.
• A short in the white or white/black wires. These can
occur at staples, or at opener connections.
• Incorrect wiring between sensors and opener.
• Loosen the sending eye wing nut and readjust, aiming
directly at the receiving eye. Lock in place.
• A broken wire.
2. If the sending eye indicator light glows steadily but the
receiving eye indicator light doesn't:
• Loosen the receiving eye wing nut and adjust sensor
until it receives the sender’s beam. When the green
indicator light glows steadily, tighten the wing nut.
• Check alignment.
• Check for an open wire to the receiving eye.
3. If the receiving eye indicator light is dim, realign either
sensor.
NOTE: When the invisible beam path is obstructed or
misaligned while the door is closing, the door will reverse.
If the door is already open, it will not close. The opener
lights will blink 10 times. See page 19.

INSTALLATION STEP 11
Fasten the Door Bracket
Fiberglass, aluminum or lightweight steel garage
doors WILL REQUIRE reinforcement BEFORE
installation of door bracket. Contact your door
manufacturer for reinforcement kit.
Follow instructions which apply to your door type
as illustrated below or on the following page.
A horizontal reinforcement brace should be long enough
to be secured to two or three vertical supports. A
vertical reinforcement brace should cover the height of
the top panel.
Header

ADJUSTMENT STEP 1
Adjust the UP and DOWN Travel Limits
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• Incorrect adjustment of garage door travel limits
will interfere with proper operation of safety
reversal system.
• If one control (force or travel limits) is adjusted,
the other control may also need adjustment.
• After ANY adjustments are made, the safety
reversal system MUST be tested. Door MUST
reverse on contact with 1-1/2" high (3.8 cm) object
(or 2x4 laid flat) on floor.
Limit adjustment settings regulate the points at which the
door will stop when moving up or down.
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
(Adjustment Step 3, page 29).
Adjustment procedures are outlined below. Read the
procedures carefully before proceeding to Adjustment
Step 2. Use a screwdriver to make limit adjustments.
Run the opener through a complete travel cycle after
each adjustment.
To prevent damage to vehicles, be sure fully open
door provides adequate clearance.
NOTE: Repeated operation of the opener during
adjustment procedures may cause the motor to overheat
and shut off. Simply wait 15 minutes and try again.
NOTE: If anything interferes with the door’s upward
travel, it will stop. If anything interferes with the door’s
downward travel (including binding or unbalanced doors),
it will reverse.
Cover Protection Bolt
2-4"
(5-10 cm)
HOW AND WHEN TO ADJUST THE LIMITS
• If the door does not open completely but opens at
least 5 feet (1.5 m):
Increase up travel. Turn the UP limit adjustment screw
clockwise. One turn equals 3" (7.5 cm) of travel.
Left Panel

(5 cm - 10 cm) between the trolley and the bolt.
• If door does not open at least 5 feet (1.5 m):
Adjust the UP (open) force as explained in Adjustment
Step 2.
ADJUSTMENT LABEL
• If the door does not close completely:
Increase down travel. Turn the down limit adjustment
screw counterclockwise. One turn equals 3" (7.5 cm)
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
Sensors are either not installed, misaligned, or
obstructed. See Troubleshooting, page 22.
If door still won't close completely and the trolley
bumps into the pulley bracket (page 4), try lengthening
the door arm (page 25) and decreasing the down limit.
Test the door for binding: Pull the emergency release
handle. Manually open and close the door. If the door is
binding or unbalanced, call for a trained door systems
technician. If the door is balanced and not binding,
adjust the DOWN (close) force. See Adjustment Step 2.
• If the opener reverses in fully closed position:
Decrease down travel. Turn the down limit adjustment
screw clockwise. One turn equals 3" (7.5 cm) of travel.
27
ADJUSTMENT STEP 2
Adjust the Force
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• Too much force on garage door will interfere with
proper operation of safety reversal system.
• NEVER increase force beyond minimum amount
required to close garage door.
• NEVER use force adjustments to compensate for a
binding or sticking garage door.
• If one control (force or travel limits) is adjusted, the
other control may also need adjustment.
• After ANY adjustments are made, the safety
reversal system MUST be tested. Door MUST
reverse on contact with 1-1/2" high (3.8 cm) object
(or 2x4 laid flat) on floor.
Force adjustment controls are located on the right panel
of the motor unit. Force adjustment settings regulate the
amount of power required to open and close the door.
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 about 3/4 of a
complete turn. Do not force controls beyond that point.
Turn force adjustment controls with a screwdriver.
NOTE: If anything interferes with the door’s upward travel,
it will stop. If anything interferes with the door’s downward
travel (including binding or unbalanced doors), it will
reverse.
Force Adjustment Controls
HOW AND WHEN TO ADJUST THE FORCES
1. Test the DOWN (close) force
Right Panel
• 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 1-1/2"
(3.8 cm) obstruction. See Adjustment Step 3,
page 29. If the door is hard to hold or doesn't
reverse, DECREASE the DOWN (close) force by
turning the control counterclockwise. Make small
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 small 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.
FORCE ADJUSTMENT LABEL
2. Test the UP (open) force
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 small adjustments until
the door stops easily and opens fully. After each
adjustment, run the opener through a complete
travel cycle.
• If the door doesn’t open at least 5 feet (1.5 m),
INCREASE UP (open) force by turning the control
clockwise. Make small adjustments until door opens
completely. Readjust the UP limit if necessary.
After each adjustment, run the opener through a
complete travel cycle.
28
Close Force
ADJUSTMENT STEP 3
Test the Safety Reversal System
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• Safety reversal system MUST be tested every
month.
• If one control (force or travel limits) is adjusted, the
other control may also need adjustment.
• After ANY adjustments are made, the safety
reversal system MUST be tested. Door MUST
reverse on contact with 1-1/2" high (3.8 cm) object
(or 2x4 laid flat) on the floor.
TEST
• With the door fully open, place a 1-1/2" (3.8 cm) board
(or 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.
ADJUST
• If the door stops on the obstruction, it is not traveling
far enough in the down direction. Increase the DOWN
limit by turning the DOWN limit adjustment screw
counterclockwise 1/4 turn.
NOTE: On a sectional door, make sure limit
adjustments do not force the door arm beyond a
straight up and down position. See the illustration on
page 25.
• Repeat the test.
• When the door reverses on the 1-1/2" (3.8 cm) board,
remove the obstruction and run the opener through
3 or 4 complete travel cycles to test adjustment.
• If the unit continues to fail the Safety Reverse Test, call
for a trained door systems technician.
IMPORTANT SAFETY CHECK:
Test the Safety Reverse System after:
• Each adjustment of door arm length, limits, or force
controls.
• Any repair to or adjustment of the garage door
(including springs and hardware).
1-1/2" (3.8 cm) board
(or a 2x4 laid flat)
• Any repair to or buckling of the garage floor.
• Any repair to or adjustment of the opener.
ADJUSTMENT STEP 4
Test The Protector System®
Without a properly installed safety reversing sensor,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• Press the remote control push button to open the door.
• Place the opener carton in the path of the door.
• Press the remote control push button to close the door.
The door will not move more than 1" (2.5 cm), and the

OPERATION
IMPORTANT SAFETY INSTRUCTIONS
WARNING
To reduce the risk of SEVERE INJURY or DEATH:
9. If one control (force or travel limits) is adjusted, the
other control may also need adjustment.
10. After ANY adjustments are made, the safety reversal
system MUST be tested.
11. Safety reversal system MUST be tested every
month. Garage door MUST reverse on contact with
1-1/2" (3.8 cm) high object (or a 2x4 laid flat) on
the floor. Failure to adjust the garage door opener
properly may cause SEVERE INJURY or DEATH.
12. ALWAYS keep garage door properly balanced (see
page 3). An improperly balanced door may NOT
reverse when required and could result in SEVERE
INJURY or DEATH.
13. ALL repairs to cables, spring assemblies and
other hardware, ALL of which are under EXTREME
tension, MUST be made by a trained door systems
technician.
14. ALWAYS disconnect electric power to garage door
opener BEFORE making ANY repairs or removing
covers.
1. READ AND FOLLOW ALL WARNINGS AND
INSTRUCTIONS.
2. ALWAYS keep remote controls out of reach of
children. NEVER permit children to operate or play
with garage door control push buttons or remote
controls.
3. ONLY activate garage door when it can be seen
clearly, it is properly adjusted, and there are no
obstructions to door travel.
4. ALWAYS keep garage door in sight until completely
closed. NO ONE SHOULD CROSS THE PATH OF THE
MOVING DOOR.
5. NO ONE SHOULD GO UNDER A STOPPED
PARTIALLY OPEN DOOR.
6. If possible, use emergency release handle to
disengage trolley ONLY when garage door is
closed. Weak or broken springs or unbalanced door
could result in an open door falling rapidly and/or
unexpectedly, causing SEVERE INJURY or DEATH.
7. NEVER use emergency release handle unless garage
doorway is clear of persons and obstructions.
8. NEVER use handle to pull garage door open or
closed. If rope knot becomes untied, you could fall.
15.
SAVE THESE
INSTRUCTIONS.
Using Your Garage Door Opener
Your Security✚® opener and hand-held remote control
have been factory-set to a matching code which changes
with each use, randomly accessing over 100 billion
new codes. Your opener will operate with up to eight
Security✚® remote controls and one Security✚® Keyless
Entry System. If you purchase a new remote, or if you
wish to deactivate any remote, follow the instructions in
the Programming section.
5. If obstructed while closing, the door will reverse. If the
obstruction interrupts the sensor beam, the opener
lights will blink for five seconds.
6. If obstructed while opening, the door will stop.
7. If fully open, the door will not close when the beam is
broken. The sensor has no effect in the opening cycle.
If the sensor is not installed, or is misaligned, the door
won't close from a hand-held remote. However, you can
close the door with the Door Control, the Outside Keylock,
or Keyless Entry, if you activate them until down travel
is complete. If you release them too soon, the door will
reverse.
Activate your opener with any of the following:
• The Hand-Held Remote Control: Hold the large push
button down until the door starts to move.
• The Wall-Mounted Door Control: Hold the push button
or bar down until the door starts to move.
The opener lights will turn on under the following
conditions: when the opener is initially plugged in; when
power is restored after interruption; when the opener is
activated.
• The Keyless Entry (see Accessories): If provided with
your garage door opener, it must be programmed
before use. See Programming.
They will turn off automatically after 4-1/2 minutes or
provide constant light when the Light feature on the
Multi-Function Door Control is activated. Bulb size is A19.
Bulb power is 100 watts maximum.
When the opener is activated (with the safety reversing
sensor correctly installed and aligned)
1. If open, the door will close. If closed, it will open.
2. If closing, the door will reverse.
3. If opening, the door will stop.
4. If the door has been stopped in a partially open
position, it will close.

1. My door will not close and the light bulbs blink on
my motor unit: The safety reversing sensor must be
connected and aligned correctly before the garage door
opener will move in the down direction.
• Verify the safety reversing sensors are properly
installed, aligned and free of any obstructions.
Refer to Installation Step 10: Install The Protector
System®.

2. My remotes will not activate the door:
• Verify your Wall-Mounted Door Control is not
blinking. If it is blinking, deactivate the Lock
Mode following the instructions for Using the
Wall-Mounted Door Control.
Sending Eye Safety Reversing
Sensor (Amber Indicator Light)
Receiving Eye Safety Reversing
Sensor (Green Indicator Light)
• Reprogram remotes following the programming
instructions. Refer to Programming.
• If remote will still not activate your door, check
diagnostic LED for flashes on motor unit then refer
to Diagnostic Chart on the following page.
3. My door reverses for no apparent reason: Repeat
safety reverse test after adjustments to force or travel
limits. The need for occasional adjustment for the force
and limit settings is normal. Weather conditions in
particular can affect door travel.
6. My motor unit hums briefly:
• Manually check door for balance or any binding
problems.
• First verify that the trolley is against the stop bolt.
• Release the door from the opener by pulling the
Emergency Release Rope.
• Refer to Adjustment Step 2, Adjust the Force.
• Manually bring the door to a closed position.
4. My door reverses for no apparent reason after fully
closing and touching the floor: Repeat safety reverse
test after adjustments to force or travel limits. The
need for occasional adjustment for the force and limit
settings is normal. Weather conditions in particular can
affect door travel.
• Loosen the chain by adjusting the outer nut 4 to 5
turns. This relieves the tension.
• Run the motor unit from the remote control or door
control. The trolley should travel towards the door
and stop. If the trolley re-engages with the door,
pull the Emergency Release Rope to disengage.
• Refer to Adjustment Step 1, Adjust the UP and
DOWN Travel Limits. Decrease down travel by
turning down limit adjustment screw clockwise.
• Decrease the up travel by turning the UP Travel
adjustment screw 2 full turns away from the arrow.
• Re-tighten the outer nut so the chain is a 1/4"
(6 mm) above the base of the rail. (When the door
is reconnected and closed, the chain will sag. This
is normal.)
5. My lights will not turn off when door is open:
• The garage door opener is equipped with a security
light feature. This feature activates the light on
when the safety reversing sensor beam has been
obstructed. Refer to Operation section; Using the
Wall-Mounted Door Control, Light Feature.
• If the trolley does not move away from the bolt,
repeat the steps above.
