Installing the Projector
The projector can be installed for four different viewing setups: front 
projection, ceiling mounting, rear projection onto a semi-transparent 
screen, or rear/ceiling projection, as shown: 
To project from overhead, you’ll need to select
Ceiling
in the
projector’s Advanced menu. To project from the rear, select
Rear
Proj
. See “Setting Advanced Features” on page 55.
If you’re mounting the projector on the ceiling and you place it above 
screen level, you’ll have to tilt it down to position the image on-screen. 
This causes the image to lose its square shape. You can then correct 
the distortion by using the 
V
Keystone
function in the projector’s
menu system (see “Customizing Projector Features” on page 53) or by 
using the 
Keystone
buttons on the projector’s control panel.
If you place the projector’s lens so it’s level with the top of the screen, 
the image will be square and you won’t have to adjust it. If you place 
the lens lower than the top of the screen, you’ll have to tilt the 
projector upward if you want to fill the whole screen with the image.
