Program the Travel

Travel limits regulate the points at which the door will stop when moving up or down.
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 cable tension monitor is not installed or
is sensing too much slack in the cable, the garage door opener light will flash 5 times.
Ensure the cable tension monitor is correctly installed then follow the steps for Program
the Travel. 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 18). 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.

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