ADJUSTMENT SECTION –

LIMIT ADJUSTMENT –

Run the opener through a complete travel cycle. Limit adjustments
are not necessary when the door opens and closes completely and
doesn't reverse unintentionally in the fully closed position.

Situations requiring limit adjustment are listed below. Run the opener
through a complete travel cycle after each adjustment.

Note:

Repeated operation of the opener during adjustment

procedures may cause motor to overheat and shut off. Allow a 15
minute cooling period after 5 continuous operations of the opener.

Read the following carefully before proceeding to Force Adjustment.
Use a screwdriver to make limit adjustments.

If Door Doesn't Open Completely but Opens at Least 1,5m (5 feet):
Increase up travel. Turn the up limit adjustment screw (1) clockwise.
One turn equals 5cm (2") of travel.

If door does not open at least 1,5m (5 feet): Adjust up (open)
force. See Force Adjustment.

If Door Doesn't Open Completely: If door arm is at maximum length,
increase down travel. Turn down limit adjustment screw (2)
counterclockwise. One turn equals 5cm (2") of travel. If the door still
will not close completely, the header bracket is positioned too high.

If Opener Reverses in Fully Closed Position: Decrease down
travel. Turn down limit adjustment screw (2) clockwise. One turn
equals 5cm (2") of travel.

If Door Reverses when Closing and there is no Interference to
Travel Cycle: Test door for binding. Pull manual release handle.
Manually open and close door. If door is binding, call a door
serviceman. If door is not binding or unbalanced, adjust
down (close) force.

PROGRAM YOUR OPENER & REMOTE –

Activate the opener only when door is in full view, free of
obstruction and properly adjusted. No one should enter or leave
garage while door is in motion. Do not allow children to operate
push button(s) or remote(s). Do not allow children to play near
the door.

Your garage door opener receiver and remote control transmitter are
set to a matching code. If you purchase additional remote controls, the
garage door opener must be programmed to accept the new remote
code.

Program the Receiver to Match Additional Remote Control Codes

1. Press and hold the remote control push button (1).

2. Press and release the "Smart" button (2) on the back panel of the

opener. The opener light will

Now the opener will operate when the remote control push button is
pressed.

If you release the remote control push button before the opener
light flashes, the opener will not accept the code.

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.

INSTALL THE LIGHT AND LENS –

Install a 40 watt maximum light bulb (1) in the socket as shown. The
light will turn on and remain lit for 4-1/2 minutes when power is
connected. After 4-1/2 minutes it will turn off.

Replace burned out bulbs with rough service light bulbs.

Apply slight pressure on sides of the lens (2) and slide tabs (3) into
slots (4) in the end panel. Reverse the procedure to remove the lens.
