Adjusting the Image Angle
If the projector is set up so that it is at a horizontal or vertical angle to the
screen, adjust as follows.
If the images are being projected onto a screen that is higher than the
position of the projector, extend the front adjustable foot to tilt the
projector.
p.44
Tilting the projector may cause a keystone distortion to the image, but the
automatic keystone correction function will automatically corrects the
image distortion.
p.46
If the projector cannot be set up directly in front of the screen, you can
project images at a horizontal angle to the screen. If keystone distortion
appears in the images, you can use the projector's "H-Keystone" and
"Quick Corner" functions to correct this keystone distortion.

The maximum downward tilt angle is when the rear adjustable foot is
extended to its limit. Do not tilt the projector downward any further
than extending the foot.
