Adjustments

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.
While programming, the UP and DOWN buttons can be used to move the door as needed.
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.
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.
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 flashing 5 times during the steps for Program the Travel, the programming
has timed out. If the garage door opener lights are flashing 10 times during the steps for Program the Travel,
the safety reversing sensors are misaligned or obstructed (refer to page 29). 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.
