Rear Ceiling
Wherever you set up the projector, make sure to position it squarely in front of the center of the screen,
not at an angle, if possible. If the projector cannot be centered in front of the screen, use lens shift to
reposition the image instead of using keystone correction for better image quality.
Note: If you use the projector tilted at an angle of more than three degrees, it could be damaged and
cause an accident.
If you project from the ceiling or from the rear, be sure to select the correct Projection setting in the
projector's Installation menu. If necessary, enable the Inv Direction Button setting in the projector's
Operation menu.

Projection Distance
The distance at which you place the projector from the screen determines the approximate size of the
image. The image size increases the farther the projector is from the screen, but can vary depending on
the zoom factor, aspect ratio, and other settings.
