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 flat) on floor.
Note: While programming the travel, the UP and DOWN buttons can be used to move the door as needed. During the
Automatic Force Setup, the door will automatically open and close.

Automatic Force Set Up

Once both the up and down positions have been manually set, the Safety Reversing Sensors will reconnect and become
operational. Then, the opener will enter a force-sensing operation by automatically moving the door open and close. The
garage door opener will sound an audible and visual alert before automatically opening and closing the door. The garage
door opener will beep three times, confirming that the Automatic Force Setup completed successfully. Adjustment is
complete.
If you hear one long beep after the door attempts to move, then the Automatic Force Set Up has not completed
successfully. Please start over at step 1 of Program the Travel.
