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 audience (and room) and your presentation style. I Place the projector on a sturdy, level surface, between 3 and 48 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 6 feet of a grounded electrical outlet or extension cord, and within 5 feet of your computer and/or video source. I Face the projector squarely toward the screen. Otherwise, your image will be distorted. Most presenters find it convenient to place the projector in the front of the audience, leaving as much space as possible between the screen and the projector. Then you can remain in front of the audience and close to the equipment. Use the figure below as a guideline to help you determine how far from the screen to place the projector. The distances are based on using the standard lens. Your image size may not exactly match the sizes shown; its actual size depends on how you position the zoom ring and whether you have adjusted the image size with other settings (such as the keystone correction or Resize button). caution Don't hold or lift the projector by the lens, or you may damage it. note It's easier to position the projector when the screen is directly in front of the room. If the screen is placed diagonally in a corner, it's much more difficult to aim the projector squarely at the screen and get a non-distorted image. 43 ft 8 ft 4 ft distance from screen Setting Up the Projector 13
