note

You can mount the projector on the ceiling, or place it behind a translucent screen for rear projection. See page 111 for details.

Positioning the Projector

If you’re setting up the projector yourself and it isn’t already installed in the classroom or conference room you’re using, you’ll probably want to place it on a table in front of the screen, as shown on

page 15.

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 size increases with distance, but can vary depending on how you position the zoom ring and whether you’ve adjusted the image with other settings.

Distance from screen

2.7 to 4.6 ft

5.7 to 9.4 ft

29.7 to 48.2 ft

Also keep these considerations in mind:■Place the projector on a sturdy, level surface.

■Make sure there is plenty of space for ventilation around and under the projector. Do not set the projector on top of loose papers that could block the vents under the projector.

■Make sure the projector is within 10 feet of a grounded electrical outlet or extension cord.
