Positioning the Projector 
If the projector isn’t already installed in the room you’re using, you’ll 
probably want to place it on a table in front of the screen, as shown.  
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 image. 
Use the figure below to help you determine placement. Image...

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 the front adjustable foot. This causes the image to become 
“keystone” shaped, but you can correct the distortion by pressing the 
buttons on the projector. See page24 for...

Turning On the Projector
Turn on any connected computer or video equipment before starting 
the projector so it can automatically detect and display the image

connected equipment, you may have to select the image...

ready for use.

your computer has found a plug-and-play monitor; if so,...
