WARNING

To prevent possible SERIOUS INJURY or DEATH, after ANY changes to the door profile, reprogram limits.

WARNING

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" high (3.8 cm) object (or 2x4 laid flat) on floor.

CAUTION

To prevent damage to vehicles, be sure fully open door provides adequate clearance.

1. With the door fully open, place a 1-1/2 inch (3.8 cm) board (or a 2x4 laid flat) 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 but does not reverse:

1. Repeat Program the Travel (see Adjustment).

2. Repeat the Safety Reversal test.

If the test continues to fail, call a trained door systems technician.

Test the Protector System®

1. Open the door. Place an obstruction 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).

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.
