Setting the Force

The Force is programmed to operate most doors, however, if Limits are not able to
be set, or the door reverses during normal operation follow this procedure: Locate
the Program Button (1) on the left side panel of unit (2). Push the Program Button
twice to enter unit into Auto-Force Adjustment Mode. The green LED will flash
slowly. Activate unit with remote and run the unit to the Open Limit. Activate unit
again to run the unit to the Closed Limit. The door must travel through a complete
cycle up and down in order for the Force to be set properly. If the unit stops before it
reaches the Open or Close Limit repeat the process. The green LED will stop
flashing when the Force has been learned.

Test the Safety Reverse System

The safety reverse system test is important. Garage door must reverse on
contact with a 40mm obstacle laid flat on the floor. Failure to properly adjust
opener may result in serious personal injury from a closing garage door.
Repeat test once a month and adjust as needed.
Procedure: Place a 40mm obstacle (1) laid flat on the floor under the garage door.
Operate the door in the down direction. The door must reverse on the obstruction.
If the door stops on the obstruction, it is not traveling far enough in the down
direction. Move Close Limit closer to door.
When the door reverses on the 40mm obstacle, remove the obstruction and run the
opener through a complete travel cycle. Door must not reverse in closed position. If
it does, adjust Limit and repeat safety reverse test.
Place 20kg at the center of the door and ensure that the door will not move up more
than 500mm.

Program Remotes
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.
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.
To program receiver to match additional Remote Control codes:
1. Press and release the program button on the side of the unit (1). The green LED
will glow steadily for 30 seconds.
2. Within 30 seconds press and hold the button on the hand-held Remote (2).
3. Release the button when the motor unit light blinks. It has learned the code. If the
light bulb is not installed, two clicks will be hear.
To erase all codes from motor unit memory or to deactivate any unwanted
Remote, first erase all codes:
Press and hold the program button (1) on motor unit until the learn indicator light
goes out (approximately 6 seconds). All previous codes are now erased. Reprogram
each Remote or Keyless Entry you wish to use.

Replace Light Bulb
Replace light bulb (1) with a 21 watt maximum light bulb. Insert bulb into socket as
shown. The light will turn on and remain lit for 2 1/2 minutes when power is
connected. After 2 1/2 minutes it will turn off.
Operation Of Your Opener
Your opener can be activated by any of the following devices:
• The Remote Control Transmitter. Hold the push button down until the door starts to
move.
• The Lighted Door Control Button (if you have installed this accessory). Hold the
button down until door starts to move.
• The Outside Keylock or Keyless Entry System (if you have installed either of these
accessories).
Opening the Door Manually:
Door should be fully closed if possible. Weak or broken springs could allow an open
door to fall rapidly. Property damage or serious personal injury could result.
The door can be opened manually by pulling the release handle down. To reconnect
the door, activate the unit.
Do not use the manual release handle to pull the door open
or closed.
When the Opener is Activated by Remote Control or Door Control Button:
1. If fully open, the door will close.
2. If closed, the door will open.
3. If opening or closing, the door will stop.
4. If partially open, the door will move in the opposite direction of last travel.
5. If an obstruction is encountered while closing, the door will reverse to the open
position.
6. If an obstruction is encountered while opening, the door will reverse for 1 second.
7. The optional Protector System™ uses an invisible beam which, when broken by
an obstruction, causes a closing door to open and prevents an open door from
closing. It is STRONGLY RECOMMENDED for homeowners with young children.
Allow a 15 minute cooling period after 5 continuous operations of the opener.
The opener light will turn on: 1. when opener is initially plugged in;
2. when the power is interrupted; 3. when the opener is activated.
The light turns off automatically after 2-1/2 minutes. Bulb size is
21 Watts maximum.
