Adjustment
1
- 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.

Press and hold the Adjustment
Button until the UP Button begins to
flash and/or a beep is heard. The
Safety Reversing Sensors will be
disconnected during the Program the
Travel process.

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.
5
Once the door is in the desired DOWN
position press and release the Adjustment
Button. The garage door opener lights will
flash twice. Program the Travel is now
complete. If the garage door opener
lights flash 5 times, then programming
has timed out and the Travel Limits have
not been set. Please restart the Program the Travel process.

- 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.
