Projector Installation
This appendix provides guidelines on installing the projector in a 
permanent location, such as a theater or conference room.
Installation Guidelines
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 the optional ceiling mounting 
hardware; see page 13 for ordering information. You’ll also need to 
select 
Ceiling in the projector’s Advanced 1 menu to flip the image 
upside-down. To project from the rear, select 
Rear Proj (see 
page 139).
Front projectionRear projection
Rear/ceiling projectionCeiling mounting 
						

							200Projector InstallationIf 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 
Keystone function in the projector’s 
menu system (see page 129) or by using the 
Keystone buttons on the 
projector’s control panel.
If you place the projector so that the base of the lens is level with the 
bottom of the screen, the image will be square and you won’t have to 
adjust it. If you place the lens lower than the bottom of the screen, 
you’ll have to tilt the projector upward if you want to fill the whole 
screen with the image. 
If you want to be able to control the projector’s settings from a remote 
computer, see Chapter 7.
You can also use the remote control to operate more than one 
projector. See page 135.
