How do I set the travel limits on my LDCO800?

Adjusting the Open Limit

Use the wall station or a remote control to move the door to the open limit position. On the back of the opener, press both the "UP" and "LEARN" buttons at the same time for three seconds. The green indicator and opener’s light will flash twice then stay on. Use the "UP" and "DOWN" buttons to jog the door at slow speed to fine-tune the open limit position. When the door is at the proper open limit position press the "LEARN" button to store the setting and exit setup. The green indicator and the opener’s light will flash two times to indicate the limit has been stored.

Adjusting the Close Limit

Use the wall station or a remote control to move the door to the close limit position. On the back of the opener, press both the "DOWN" and "LEARN" buttons for three seconds. The red indicator and opener’s light will flash twice then stay on. Use the "UP" and "DOWN" buttons to jog the door at slow speed to fine-tune the close limit position. When the door is at the proper close limit position, press the "LEARN" button to store the setting and exit setup. The red indicator and the opener’s light will flash two times to indicate the limit has been stored.
