note It's easier to position the projector when the screen is directly in front of the room. However, if you need to place it off-center, you can use the keystone correction feature to maintain a square image. See page 27 for more information. Positioning the Projector Before connecting the projector, you need to decide where to place it. The location you choose depends on the size of the room and what you are projecting. I Place the projector on a sturdy, level surface, approximately 2.85 to 41 feet from the screen. I Make sure there is plenty of space for ventilation around and under the projector. I Make sure the projector is within 10 feet of a grounded electrical outlet or extension cord, and within 5 feet of your computer and/or video source. I Place the projector directly in front of the center of the screen, facing it toward the screen squarely. Most presenters find it convenient to place the projector in front of the audience, leaving as much space as possible between the projector and the screen to get a good-sized image. This lets the presenter stand in the front of the room, face the audience, and remain close enough to the equipment to be able to control it. Use the figure below as a guideline to help you determine how far from the screen to place the projector. Image size generally increases with distance, but may vary depending on how you position the zoom ring and whether you have adjusted the image size with other settings. 30 to 41 ft 6 to 8 ft 3 to 4 ft distance from screen 10 Setting Up the Projector
