OPERATION OF YOUR OPENER
Your opener can be activated by any of the following devices:
· Opener Control Panel: UP & DOWN buttons, and O.S.C. control button.
· Remote Control Transmitter: hold the button down until the door starts to move.
· Wireless Entry Keypad: This is an accessory that opens the door using a four digit keycode.
When the opener is activated:
· If open, the door will close. If closed, the door will open
· If closing, the door will stop · If opening, the door will stop (allowing space for
entry and exit of pets and for ventilation) · If the door has been stopped in a partially open or
closed position, it will reverse direction

CARE OF YOUR OPENER
When properly installed, your opener will operate with minimal maintenance. The opener does not require additional lubrication.
Limit and Force Settings: These settings must be checked and properly set when the opener is installed. Weather conditions may cause some minor changes in the door operation, requiring some re-adjustments, particularly during the first year of operation. Refer to limit and force setting in section 14.
Follow the instructions carefully and repeat the safety reverse test after any adjustment.
Transmitter: Additional transmitters can be purchased at any time. Refer to www.liftmaster.eu for compatible transmitters. Any new transmitters must be programmed into the opener.
Transmitter battery: If the transmission range decreases, replace the battery.

Obstruction behaviour:
· If an obstruction is encountered while closing, the door will reverse
· If an obstruction is encountered while opening, the door will reverse and stop
· Obstruction detection beams use 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 or pets.

MAINTENANCE OF YOUR OPENER
Once a Month:
· Repeat the safety reverse test (see section 15). Make any necessary adjustments.
· Manually operate the door. If it is unbalanced or binding, call for professional garage door service.
· Check to be sure that the door opens and closes fully. Set the limits and/or force if necessary.

Opening the door manually:
When releasing the door, the door should be fully closed if possible. Weak or broken springs could allow an open door to fall rapidly. Property damage or serious injury could result.
The door can be opened manually by pulling the release cord down firmly. To re-engage the door, pull the release cord down firmly.
The opener light will turn on for 3 minutes when the opener is activated.

replaced by contacting a garage door repairer.

2. Opener operates from the transmitter, but not from the wired wall control terminals:
· Check that the wiring connections are correct.
3. The door operates from the UP/DOWN activation buttons but not from the wireless wall control or transmitter:
· Program the opener to match the transmitter code.

9. The opener strains to operate the door: · The door may be out of balance or the springs may be
broken. Close the door and use the manual release to disconnect the door. 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 trained door systems technician.

Repeat with all transmitters.
4. The transmitter has short range: · Change the location of the transmitter. · Check to be sure the antenna on the bottom of the
opener extends fully downward. · Some installations may have shorter range due to a
metal door, foil backed insulation, or metal garage siding.

10. The opener motor hums briefly, then will not work:
· Check that the door is not in manual release mode (refer to sections 9 or 10).
· The garage door springs may be broken. · If the problem occurs on the first operation of the
opener, the door may be locked. Disable any door locks.

· The batteries may be flat. Replace the batteries.
5. The garage door opens and closes by itself: · Be sure that no transmitter buttons are being pressed. · Clear the memory and re-program all wireless wall
controls and transmitters.

11. The opener will not operate due to a power failure:
· Use the manual release handle to disconnect the door. The door can be opened and closed manually. When power is restored, re-engage the opener to operate it via a transmitter.

6. The door reverses and stops before opening completely:
· Is something obstructing the door? Is it out of balance, or are the springs broken? Remove the obstruction or repair the door.

12. The LED Indicators on the control panel are flashing in sequence:
· Check the diagnostic code in section 28.

7. Door reverses for no apparent reason and opener lights flash 10 times:
· Check the obstruction detection beams (if you have installed this accessory). If the red light on the beam is flashing, the alignment is incorrect.
· The red light on the beams may not be on if the opener is in Standby mode. Activate the door to temporarily exit standby mode and check lights are on constantly. If the LEDs are flashing, realign the beams.
