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.
Turn power on
Setting the limits :
1. Press and hold the black button until the yellow
indicator light starts flashing slowly then release.
2. Adjust the desired up position of the door by using
the black and orange buttons. Black moves the
door UP (open) and orange moves the door DOWN
(close). Check to be sure the door opens high
enough for your vehicle.
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).
The Force must now be set in order to complete your
installation. Go to section 23.

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 wireless wall button (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.
