The Limit Positions can vary due to site conditions, such as
uneven ground. When setting the Close limit, ensure the
position is when the door makes first contact with the ground.
Alternatively for the Open limit the position should be at the
height of the garage opening.

This may not be suitable for larger doors.
a. Move the door to the half way position.
b. Engage the opener by pulling down on the manual release
string until a click sounds.
c. Switch power on and the BLUE LED on the BLUE CLOSE
button will start to flash.
WARNING! In setting the close limit
position, do not force the door into the floor
with excessive force, as this can interfere
with the ease of operation of the manual
release mechanism.

open and close again after the next step.
