Adjustment

Program the travel

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.
• After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" (3.8 cm) high object (or 2x4 laid fl at) on floor.

1. Press and hold the Adjustment Button until the UP Button begins to flash and/ or a beep is heard.
   
2. Press and hold the UP Button until the door is in the desired UP position.
   
   NOTE: The UP and DOWN Buttons can be used to move the door up and down as needed.
3. Once the door is in the desired UP position press and release the Adjustment Button. The garage door opener lights will flash twice and the DOWN Button will begin to flash.
   
4. Press and hold the DOWN Button until the door is in the desired DOWN position.
   
   NOTE: The UP and DOWN Buttons can be used to move the door up and down as needed.
5. Once the door is in the desired DOWN position press and release the Adjustment Button. The garage door opener lights will flash twice and the UP Button will begin to flash.
   
6. Press and release the UP Button. When the door travels to the programmed UP position, the DOWN Button will begin to flash.
   
7. Press and release the DOWN Button. The door will travel to the programmed DOWN position. Programming is complete.
   

* If the garage door opener lights are fl ashing 5 times during the steps for Program the Travel, the programming has timed out. If the garage door opener lights are fl ashing 10 times during the steps for Program the Travel, the safety reversing sensors are misaligned or obstructed. When the sensors are aligned and unobstructed, cycle the door through a complete up and down cycle using the remote control or the UP and DOWN buttons. Programming is complete. If you are unable to operate the door up and down, repeat the steps for Programming the Travel.

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.
• 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 fl at) on the floor.

1. With the door fully open, place a 1-1/2 inch (3.8 cm) board (or a 2x4 laid fl at) on the floor, centered under the garage door.
   
2. Press the remote control push button to close the door. The door MUST reverse when it makes contact with the board.
   

If the door stops and does not reverse on the obstruction, increase the down travel (refer to Adjustment Step 1).
Repeat the test. When the door reverses upon contact with the 1-1/2 inch board, remove the board and open/close the door 3 or 4 times to test the adjustment.
If the test continues to fail, call a trained door systems technician.

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.

1. Open the door. Place the garage door opener carton in the path of the door.
   
2. Press the remote control push button to close the door. The door will not move more than an inch (2.5 cm), and the garage door opener lights will flash 10 times.
   

The garage door opener will not close from a remote control if the LED in either safety reversing sensor is off (alerting you to the fact that the sensor is misaligned or obstructed).
If the garage door opener closes the door when the safety reversing sensor is obstructed (and the sensors are no more than 6 inches [15 cm] above the floor), call for a trained door systems technician.

Synchronize the Door Control

To synchronize the door control to the garage door opener, press the push bar until the garage door opener activates (it may take up to 3 presses). Test the door control by pressing the push bar. Each press of the push bar will activate the garage door opener.
