SETTING THE LIMITS
Travel limits regulate the points at which the door will stop
when moving up or down. Follow the steps below to set
the limits.
NOTE: The door must be in the mid or closed position
to begin setting the limits.
Setting the limits:
1. Press and hold the black button (1) until the yellow
indicator (3) light starts flashing slowly then release.
2. Adjust the position of the door to the desired UP
position by using the black button. Black (1) moves the
door UP (open) and orange (2) moves the door DOWN
(close). Check to be sure the door opens high enough
for your vehicle to pass under.
3. Push the transmitter or door control. This sets the UP
(open) limit and begins closing the door.
Immediately press either the orange or the black
button. The door will stop.
4. Adjust the desired DOWN (close) limit position using
the black and orange buttons. Check to be sure the
door is fully closed without applying excessive pressure
on the rail (rail should not bow upwards and the chain
should not sag or droop below the rail). Push the
transmitter or door control. This sets the DOWN (close)
limit and begins opening the door.
5. Open and close the door with the transmitter or door
control 2 or 3 times (leave door in open position ready
for force setting).
NOTE: The force must now be set in order to
complete your installation (refer section 22).

SETTING THE FORCE
The force setting button is located behind the light lens of the
opener. The force setting regulates the amount of power
required to open and close the door.
1. Open the light lens. Locate the orange button (2).
2. Push the orange button (2) twice to enter unit into Force
Adjustment Mode. The LED (3) (indicator light) will flash quickly.
3. Push the programmed transmitter (4) or push bar on the door
control (if installed). The door will travel to the DOWN (close)
position. Push the transmitter (4) again, the door will travel to
the UP (open) position.
The LED (3) (indicator light) will stop flashing when the force has
been learned.
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 ensure that it is
balanced properly and is not sticking or binding.
The force MUST be learned in order to properly complete the
setting of the limits.
