    The value for L (distance to screen)
    varies slightly depending on the zoom

    When the shortest projection distance is
    used, a small amount of distortion may
    occur in the image due to the zoom lens
    characteristics.

    (diagonal) Height from the edge of screen
    to centre of lens (H)
    Projection distance (L)
    Min (wide) Max (telephoto)
    Calculation of the projection distance
    For a s creen size different from the above, u se the equation below to calculate the projection di stance.
    A spect ratio 4 : 3
    minimum L (m) = (diagonal  screen  size in inches ) x 0.0292 – 0.036
    maximum L (m) = (diagonal  screen  size in inches ) x 0.0351 – 0.044
    NOTE: Distances calculated with the above equations will include a sligh\
    t error.
    Installable Angle
    Install the projector at an angle within the range  shown below.
    • Vertical direction
    The projector
    may be ins talled
    at a vertical
    angle of ±30°. • Vertical direction
    The projector may not be angled horizontally.

    PT-LB75NTPortable LCD Projector
    As of May 2008< 6 >
    Computer data compatibility
    This projector accepts up to 91 kHz horizontal scanning frequency and 162 MHz dot clock.
    NOTE: Pixel thinning is applied to signals that exceed a dot clock frequency of 100 MHz. The display resolution of this projector is 1,024 x 768
    pixels. Input signals that exceed this resolution will be converted to 1,024 x 768 pixels.
    List of compatible signals
    1. The “i” appearing after the resolution indicates an interlaced signal. 
    2. The following symbols are used to indicate picture quality.
    AA Maximum picture quality can be obtained. 
    A Signals are converted by the image processing circuit before picture is projected.
    B Signals are compressed by the image processing circuit before picture is projected.
    3. When 750 (720)/60p or 750 (720)/50p signals are input to a computer input terminal, images are projected in the WIDE750 (720) format. Be sure
    to run the auto setup function.

    Serial connector
    The serial connector complies with RS-232C. To control the projector from a personal computer, com-
    mands must be input through communication software, based on the format and satisfying the commu-
    nication conditions shown below.
    Pin assignments and signal names
    Communication conditions (factory setting)
    Basic format
    Transmission from the computer begins with STX, then the ID, command, parameter, and ETX are sent
    in this order. Add parameters according to the details of control.
    CAUTION
    It may not be possible to send or receive commands for about 10 to 60 seconds when the lamp is first turned on. If this occurs, wait for 60 seconds, then
    try sending or receiving again. When sending multiple commands, be sure to wait for at least 0.5 second after receiving a respo nse from the projector
    before sending the next command. Additional time is sometimes required for response due to processing inside the projector. Set  the time-out period for
    command response to 10 seconds or more.
    NOTE:
    If a wrong command is received, the projector will send an ER401 command to the computer. 
    When sending commands without parameters, a colon (:) is not necessary\

    Control commands
    *1
    Do not send PON, POF, or OSH commands continuously in a short period of time. Doing so may burst the lamp or shorten the lamp replacement cycle.
    *2
    When a command other than OSH is sent while the shutter function is operating, the projector will send an ER401 command in reply and release the shutter function.

    Notes on Projector Placement and Operation: 
    The projector uses a high-wattage lamp that becomes very hot during operation. Please observe the
    following precautions.
    1. Never place objects on top of the projector while it is operating.
    2. Make sure there is an unobstructed space of 150 mm (5-29/32˝) or more around the projector’s
    exhaust openings.
    3. If the projector is placed in a box or enclosure, ensure the temperature of the air surrounding the
    projector is between 0°C/32°F and 35°C/95°F. Also make sure the projector’s intake and exhaust
    openings are not blocked. Take particular care to ensure that hot air from the exhaust openings is
    not sucked into the intake openings.
    Direction of Air Intake and Exhaust
    200 mm (7-7/8˝) or more 500 mm (7-5/8˝) or more 500 mm (7-5/8˝) or more
    Operating the Projector Continuously
    1.  If the projector is to be operated continuously 10 hours or more, lamp replacement cycle duration
    becomes shorter. 
    2.  The lamp replacement cycle duration becomes shorter if the projector is operated repeatedly for short
    periods (one hour or less).
