2. Push the orange button twice to enter unit into Force Adjustment
Mode. The LED (Indicator Light) will flash quickly.
3. Push the remote control or door control. The door will travel to the
DOWN (close) position. Push the remote control or door control again,
the door will travel to the UP (open) position. Push the remote control
or door control a third time to send the door to the DOWN (close)

The LED (Indicator Light) will stop flashing when the force has been
learned.
The unit has learned the forces required to open and close your door.
The door must travel through a complete cycle, UP and DOWN, in order
for the force to be set properly. If the unit cannot open and close your
door fully, inspect your door to insure that it is balanced properly and is
not sticking or binding.
See page 3, “Preparing your door.”
