    “Plug and Play” function (when connecting to a 15-pin terminal)
    This projector is compatible with VESA-standard DDC 1/DDC 2B. The projector and a VESA DDC
    compatible computer will communicate their setting requirements, allowing for quick and easy setup.
    Before using the “Plug and Play” function, be sure to turn on the projector first and the connected
    computer last.
    Note
    •The DDC “Plug and Play” function of this projector operates only when used in conjunction with a VESA

    Connecting to Video
    Equipment Using an
    S-video, a Composite
    Video or an Audio Cable
    Using an S-video, video, or audio cable, a VCR,
    laser disc player or other audio-visual equipment
    can be connected to INPUT 2, INPUT 3 and AU-
    DIO input terminals.
    1Connect the projector to the
    video equipment using an S-
    video cable or a composite video
    cable (both commercially avail-
    able).
    2Connect the projector to the
    video equipment using a ø3.5
    mm minijack to RCA audio cable
    (commercially available).
    Note
    •The INPUT 2 (S-VIDEO) terminal uses a
    video signal system in which the picture is
    separated into color and luminance signals
    to realize a higher-quality image. To view a
    higher-quality image, use a commercially
    available S-video cable to connect the IN-
    PUT 2 terminal on the projector and the S-
    video output terminal on the video equip-
    ment.

    Connecting to a
    Computer Using a DIN-D-
    sub RS-232C Adaptor
    and an RS-232C Serial
    Control Cable
    When the RS-232C terminal on the projector is
    connected to a computer with a DIN-D-sub RS-
    232C adaptor and an RS-232C serial control
    cable (cross type, sold separately), the computer
    can be used to control the projector and check
    the status of the projector. See page 61 for de-
    tails.
    1Connect the supplied DIN-D-sub
    RS-232C adaptor to an RS-232C
    serial control cable (sold sepa-
    rately).
    2Use the above cables to connect
    the projector and the computer.
    Note
    •Do not connect or disconnect an RS-232C
    serial control cable to or from the computer
    while it is on. This may damage your com-
    puter.
    •The RS-232C function may not operate if
    your computer terminal is not correctly set
    up. Refer to the operation manual of the
    computer for details.

    Setup
    Using the Adjustment
    Feet
    The height of the projector can be adjusted us-
    ing the adjustment feet at the front and rear of
    the projector when the surface the projector is
    placed on is uneven or when the screen is
    slanted.
    The projection of the image can be made higher
    by adjusting the projector when it is in a lower
    place than the screen.
    1While pressing the foot releases
    on both sides, lift the projector
    to adjust its height and then re-
    move your fingers from the foot
    releases.
    2Rotate the adjustment feet at the
    front of the projector for fine
    adjustment.
    •You can adjust the projection by using
    the rear adjustment foot on the bottom
    of the projector when the projector is po-
    sitioned at the higher place than the
    screen.
    Note
    •The Keystone Correction will be automatically
    performed when the projector is tilted. If you
    want to adjust the Keystone Correction
    manually, see page 29. (For details on set-
    ting of the Keystone Correction, see page 44.)
    •When returning the projector to its original
    position, hold the projector firmly, press the
    foot releases and then gently lower it.
    •The projector is adjustable up to approxi-
    mately 12 degrees at the front and 3 degrees
    at the back from the standard position.
    Info
    •Do not press the foot releases when the ad-
    justment feet are extended without firmly
    holding the projector.
    •Do not hold the lens when lifting or lower-
    ing the projector.
    •When lowering the projector, be careful not
    to get your fingers caught in the area between
    the adjustment foot and the projector.

    Adjusting the Lens
    The image is focused and adjusted to the de-
    sired size using the focus ring or zoom knob

    Example of standard setup
    Setting up the Screen
    Position the projector perpendicular to the screen with all feet flat and level to achieve an optimal image.
    Note
    •The projector lens should be centered in the middle of the screen. If the horizontal line passing through the
    lens center is not perpendicular to the screen, the image will be distorted, making viewing difficult.
    •For an optimal image, position the screen so that it is not in direct sunlight or room light. Light falling directly
    on the screen washes out the colors, making viewing difficult. Close the curtains and dim the lights when
    setting up the screen in a sunny or bright room.
    •A polarizing screen cannot be used with this projector.
    Standard Setup (Front Projection)
    Place the projector at the required distance from
    the screen according to the desired picture size.
    (See page 24.)
    Side View
    Top View
    •The distance from the screen to the projector
    may vary depending on the size of the screen.
    P.24
    •The default setting can be used, when placing the
    projector in front of the screen. If the projected im-
    age is reversed or inverted, readjust the setting to
    “Front” in the “PRJ Mode” menu.P.50
    •Place the projector so that an imaginary horizontal
    line that passes through the center of the lens is
    perpendicular to the screen.

    Place a mirror (normal flat type) in front of the lens.
    Info
    •When using a mirror, be sure to carefully position both the
    projector and the mirror so the light does not shine into the
    eyes of the audience.
    Ceiling-mount Setup
    It is recommended that you use the optional Sharp ceiling-
    mount bracket for this installation.
    Before mounting the projector, contact your nearest Sharp
    Authorized Projector Dealer or Service Center to obtain the
    recommended ceiling-mount bracket (sold separately).
    •AN-PGCM95 ceiling-mount bracket, its AN-EP101B
    extension tube and AN-JT299 universal bracket, adaptor
    for non-level ceiling installation (for U.S.A.).
    •BB-A10T ceiling adaptor, its BB-NVHOLDER280, BB-
    NVHOLDER550, BB-NVHOLDER900 ceiling mount
    systems (for GERMANY).
    •AN-A10T ceiling-mount bracket, its AN-TK201 and AN-
    TK202 extension tubes (for countries other than the U.S.A.
    and GERMANY).
    Be sure to adjust the position of the
    projector to match the distance (H)
    from the lens center position (see page
    24) to the lower edge of the image,
    when mounting the projector on the
    ceiling.
    Invert the image by setting
    “Ceiling+Front” in the
