    Throw Distance and Screen Size
    The following shows the proper relative positions of the projector and screen. Refer to the table to determine the position of installation.
    Reflecting the Image
    Using a mirror to reflect your projectors image enables you to enjoy a
    much larger image. Contact your NEC dealer if you need a mirror. If youre
    using a mirror and your image is inverted, use the MENU button and
    SELECT dial on your projector cabinet or the MENU and the 
    buttons on your remote control to correct the orientation. (See page E-
    33.) WARNING
    *Installing your projector on the ceiling must be done by a quali-
    fied technician. Contact your NEC dealer for more information.
    *Do not attempt to install the projector yourself.
    •Only use your projector on a solid, level surface. If the projector falls to
    the ground, you can be injured and the projector severely damaged.
    •Do not use the projector where temperatures vary greatly. The projec-
    tor must be used at temperatures between 41˚F (5˚C) and 95˚F (35˚C).
    •Do not expose the projector to moisture, dust, or smoke. This will harm
    the screen image.
    •Ensure that you have adequate ventilation around your projector so
    heat can dissipate. Do not cover the vents on the side or the front of
    the projector.
