Setting

Fan control

This function is used to set the cooling fans’ operation to the projector’s setting environment. Set this function properly in accordance with the projector’s installation method.

Otherwise, the cooling fans will not work properly and that causes malfunctions of the projector and decreases the lamp life.

Slant

Select the projector’s installation condition from the following options:

Off	When using the projector within the range of the
	upward/ downward inclination of 20 degrees to
	the horizontal plane.
L1	When using the projector within the range of the
	upward inclination of over 20 degrees to the
	horizontal plane.
L2	When using the projector with downward
	inclination of over 20 degrees to the horizontal
	plane.
