Whether you’re presenting from a computer or video equipment, 
you need to follow some basic steps to display your image on the 
screen. 
Follow the guidelines in this chapter for:

■Turning the projector on and selecting the image source

■Adjusting the image
■Turning off the projector

Positioning the Projector
If you’re setting up the projector yourself and it isn’t already installed 
in the theater or conference room you’re using, you’ll probably want 
to place it on a table in front of the screen, as shown.  x art below
This lets you stand in the front of the room, face the audience, and 
remain close enough to the equipment to be able to control it. Try to 
leave as much space as possible between the projector and the screen to 
get a good-size...

Displaying and Adjusting the Image17
Ideally, you should place the projector directly in front of the center of 
the screen, facing it toward the screen squarely. The base of the lens 
should be at about the level of the bottom of the screen.  
If you place the projector below screen level, you’ll have to tilt it up by 
extending its feet. This causes the image to become “keystone” shaped, 
but you can correct the distortion by pressing the 
Sync buttons on the 
projector. See page 26 for detailed...

Projecting the Image
Make sure your projector and other equipment are set up as described 
in Chapter 3. Then follow the instructions below to start the projector 
and display an image. 
Turning on the Projector
If you turn on any connected computer or video equipment before 
starting the projector, this lets the projector automatically detect and 
display the image source. If you turn on the projector first, or have 
multiple pieces of connected equipment, you may...

the P
Power button on the remote control.
(If this is your first time using the remote control, make sure the 
batteries are installed and the 
ON/OFF switch on the side of the 
remote is turned on.) 
The Ppower light flashes green as the projector warms up, and an 
image begins to appear. When the Ppower light stops flashing 
and remains green (in about 40 seconds) the projector is ready 
for use.

Selecting the Image Source
Selecting the image source lets you switch between images input from 
different pieces of equipment connected to the projector (such as a 
computer or DVD player). 
If you don’t see the image you want, select it using the 
Source 
buttons either on the projector or the remote control. 
The 
Source buttons work as follows:
■The projector has two Source buttons. Use the Computer/DVI 
button to switch between
