ADJUSTMENT STEP 2

The force setting measures the amount of force required
to open and close the door.
1. Push the purple button twice to enter into the Force
Adjustment Mode (Figure 2). The LED will fl ash quickly.
2. Push the door control or programmed remote control
(Figure 3). The door will close (DOWN).
3. Push the door control or programmed remote control
again (Figure 3). The door will open (UP).
4. Push the door control or programmed remote control
(Figure 3) a third time to close the door (DOWN).
The LED will stop fl ashing when the force has been
programmed.
The door must travel through a complete cycle, up and
down, in order for the force to be set properly. If the
garage door opener cannot open and close the door fully,
inspect the door to ensure that it is balanced properly and
is not sticking or binding.
If the door is not stopping exactly where you would like it,
repeat Program the Travel Limits.
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• Too much force on garage door will interfere with
proper operation of safety reversal system.
• NEVER use adjustments to compensate for a binding
or sticking garage door.
• After ANY adjustments are made, the safety reversal
system MUST be tested. Door MUST reverse on
contact with 1-1/2" (3.8 cm) high object(or 2x4 laid
