ADJUSTMENTS
PROGRAM THE TRAVEL
Your garage door opener is designed with electronic controls to
make setup and adjustments easy. The adjustments allow you
to program where the door will stop in the open (UP) and close
(DOWN) position. The electronic controls sense the amount of
force required to open and close the door. The force is adjusted
automatically when you program the travel and cannot be
changed.
To prevent damage to vehicles, be sure fully open door
provides adequate clearance.
Setting the UP position:
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.
Setting the DOWN position:
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.

the programmed UP position, the DOWN Button will begin to
flash.

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
