The force setting button is located on the front panel.
The force setting measures the amount of force
required to open and close the door.
1. Locate the purple button on the unit (Figure 1).
2. Push the purple button twice to enter unit into Force
Adjustment Mode (Figure 2). The LED (Indicator Light)
will flash quickly.
3. Push the Single Button Control Station (Figure 3). The
door will travel to the DOWN (close) position. Push the
Single Button Control Station again, the door will travel
to the UP (open) position. Push Single Button Control
Station a third time to send the door to the DOWN
(close) position.
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 4, “Preparing your door.”

Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing door.
• NEVER learn forces or limits when door is binding or
sticking. Repair door first
• Too much force on door 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.
