    Installation
    Rear screen installations
    There are two basic types of rear screens: diffused and optical.
    A diffusion screen has a sur face that spreads the light striking it. Purely diffused screens 
    have a gain of less than 1. The main advantage of the diffused screen is its wide viewing 
    angle, similar to that of a flat screen for front screen projection. This type of screen is suitable 
    when a wide viewing angle is required but there is low ambient room lighting.
    Optical screens take light from the projector and redirect it to increase the light intensity 
    at the front of the screen. This reduces it in other areas. A viewing cone similar to that of a 
    curved, front-screen installation is created. This type of screen is better suited for brightly 
    lit rooms where the audience is situated within the viewing cone.
    Screen size
    Choose a screen size that is appropriate for your lens and application. The size of the room 
    and viewing distance are the defining factors; a rule of thumb is that the primary viewing 
    distance be 1.5 times the screen width.
    To fill a screen with an image, the aspect ratio of the screen should be equal to the aspect 
    ratio of the image (expressed as the ratio of its width to its height). Standard video from a 
    VCR has a 4:3 or 1.33:1 aspect ratio. For example, to display a VCR output with a 4:3 aspect 
    ratio onto a 10-foot (3.05-meter) high screen, the width of the screen must be at least 13.3 
    feet (4 meters).

    Installation
    Ambient Light In general, minimize or eliminate light sources directed at the screen. Contrast ratio in 
    your images will be noticeably reduced if light directly strikes the screen, such as when 
    a shaft of light from a window or floodlight falls on the image. Images may then appear 
    washed out and less vibrant.
    Other considerations and tips that can help improve your installation:
    •   Keep the ambient temperature constant and below 35°C (95°F). Keep the projector 
    away from heating and/or air conditioning vents. Changes in temperature may cause 
    drifts in the projector circuitry, which may affect per formance.
    •   Keep the projector away from devices that radiate electromagnetic energy such as 
    motors and transformers. Common sources of these include slide projectors, speakers, 
    power amplifiers and elevators. 
    Throw distance is the distance measured from your projector ’s lens to the screen. This is 
    an important calculation in any projector installation as it determines whether or not you 
    have enough room to install your projector with a desired screen size and if your image 
    will be of the right size for your screen.
    You can quickly estimate the throw distance by taking the width of the screen and 
    multiplying it by the lens throw ratio. ( The Model 50 has a lens throw ratio of between 
    1.82 and 2.42.)

    Throw Distance
    The result of this calculation tells you roughly how far back the projector should be positioned 
    from the screen in order to project a focused image large enough to fill the screen. 
    For example, with an 8-foot (96-inch) wide screen (the maximum recommended screen 
    width for this projector), the Model 50 has a throw distance range of between 174.72 inches 
    (4.44 meters) and 232.32 inches (5.90 meters).

    Installation
    Vertical and Horizontal 
      PositionProper placement of the projector relative to the screen will yield a rectangular, perfectly-
    centered image that completely fills the screen. 
    Ideally, the projector should be positioned perpendicular to the screen and in such a way 
    that the lens center is aligned with either the top or bottom edge of the screen area, and 
    centered horizontally.  
    The top of the projected image is even with the lens center when the projector is inverted 
    (ceiling-mounted). Likewise, the bottom of the projected image is aligned with the lens 
    center when the projector is upright (as in a floor installation).

    If it is not possible to align the projector and screen as shown above, you can tilt the projector 
    at a slight angle. In a ceiling installation, you do this by adjusting the ceiling mount. For 
    a floor installation, turn the four adjustable feet on the bottom of the projector to adjust 
    the projector height and/or projection angle.
    If you do this, you may need to make keystone adjustments or vertically shift the image 
    using the on-screen display (OSD) controls, to compensate. For detailed instructions, refer 
    to  On-Screen Display Menus , later in this manual.

    Installation
    MountingThere are several methods for mounting the projector. Depending on your chosen 
    installation, one method may be more suitable than another. In typical front and rear 
    screen installations the projector can be mounted to a secure and level sur face, such as a 
    table or cart. Carts are useful when moving a projector during a presentation or from site 
    to site. If possible, lock the wheels when it’s in position to prevent it from being moved 
    during a presentation.
    CEILING MOUNT—The projector can also be inverted and suspended from the ceiling 
    using a specially designed ceiling mount fixture. This type of mounting is recommended 
    for fixed installations and for those that want the projector out of sight or have a limited 
    space for projector and audience.
     Use only the Vidikron-approved ceiling mount kit designed for your projector. 
    In rear screen applications where space behind the projector is limited, a mirror may be 
    used to fold the optical path, as shown below. The position of the projector and mirror 
    must be accurately set. If you are considering this type of installation, contact your dealer 
    for assistance.

    Turning on the Power•  Turn on the main power switch on the rear 
    of the projector. The POWER LED will light 
    orange.
    •  Press the ON button on the remote control 
    to turn on the projector. The POWER LED 
    flashes orange during the warm up period, 
    then lights solid green.
    •  “Searching….” appears on the screen before 
    the projector identifies the input signal, 
    and remains there until a valid signal is 
    detected.
    •  If an incompatible input signal exceeds 
    the  range of the projector, a “No signal 
    supported” message appears on the screen. 
    This message remains on the screen until 
    you change the input signal.
    •  To adjust the projector height or projection 
    angle, or to compensate for a mounting 
    sur face  that  isn’t  level,  turn  the  four 
    adjustable feet on the bottom of the 
    projector.
