    Important Operating Considerations for Safety Place the projector in a horizontal position no greater than 15 degrees 
    off axis. Locate the projector in a well-ventilated area without any obstructions 
    to intake or exhaust vents. Do not place the projector on a tablecloth or 
    other soft covering that may block the vents.  Locate the projector at least 4 (1.2 m) away from any heating or cooling 
    vents. Use only InFocus-approved ceiling mounts. Use only the power cord provided. A surge-protected power strip is 
    recommended. Refer to this guide for proper startup and shutdown procedures. This product has a lamp which contains a very small amount of mer
    -
    cury. Wash hands after cleaning the area and handling the ruptured 
    lamp. Dispose of it as required by local, state or federal ordinances and 
    regulations. For more information see www.eiae.org.
     In the unlikely event of a lamp rupture, particles may exit through the 
    projector side vents. When the projector is turned on, keep people, 
    food, and drinks out of the keep out area under and around the pro
    -
    jector, as indicated by the X areas below.
    Follow these instructions to help ensure image quality and lamp life over 
    the life of the projector. Failure to follow these instructions may affect the 
    warranty. For complete details of the warranty, see the Warranty booklet.

     7 for details.
     
    The projector also provides the following connectors: RS-232 for serial control (not included on the IN72) 12 volt DC output (see below)   12 volt DC outputThe 3.5mm mini-jack trigger provides a 12 volt, 0.25 amp DC output. It pro
    -
    vides a constant output while the projector is on. It has numerous uses. For 
    example, if you connect your projection screen to the 12 volt DC output 
    with the cable that came with your screen, when you turn on the projector 
    the screen will move down; when you turn the projector off, the screen will 
    return to the storage position.

    Positioning the projectorTo determine where to position the projector, consider the size and shape of 
    your screen, the location of your power outlets, and the distance between 
    the projector and the rest of your equipment. Here are some guidelines: Position the projector on a flat surface at a right angle to the screen. The 
    projector must be at least 4.9 feet (1.5m) from the projection screen. For safety reasons, position the projector within 10 feet (3m) of your 
    power source (running extension cables may introduce a trip hazard). 
    To ensure adequate cable access, do not place the projector within 6 
    inches (.15m) of a wall or other object. If you are installing the projector on the ceiling, refer to the installation 
    guide that comes with the Ceiling Mount Kit for more information. To 
    turn the image upside down, see “Ceiling” on 
    page
     26. We recommend 
    using an InFocus authorized ceiling mount.
     Position the projector the desired distance from the screen. The distance 
    from the lens of the projector to the screen, the zoom setting, and the 
    video format determine the size of the projected image.  The image offset is 128% for the IN72. This means that if you have an 
    image 10’ high, the bottom of the image will be 2.8’ above the center of 
    the lens. For the IN74 and IN76, the image offset is 115%.

    Choosing the aspect ratioAspect ratio is the ratio of the image width to image height. HDTV and 
    most DVDs are 16:9, which is the default for this projector. When in 4:3 
    mode the projector places black bars on both sides of the image. Native 
    mode centers the image and turns off the internal scaler so that any resolu
    -
    tion larger than the native projector resolution is cropped on the edges. Let
    -
    terbox expands the image to fill the screen.What you plan to project will also help you choose between 4:3 and 16:9. For 
    example, most TV shows are 4:3, while most movies are 16:9. If you have a 
    16:9 screen, then you should select an aspect ratio of 16:9 for anamorphic 
    movies and HDTV, and Native for 4:3 content. If you have a 4:3 screen you 
    should still use 16:9 for anamorphic movies or HDTV, but you also have the 
    option of using 4:3, Native, or Natural Wide for 4:3 content. Keep in mind 
    that anamorphic movies only appear correctly if the DVD player is set to 
    output to a 16:9 television. Natural Wide stretches a 4:3 image to fill the 
    entire 16:9 screen. The center two-thirds of the image is unchanged; the 
    edges of the image are stretched.

    to get sound.You can connect the projector to most video devices that can output video. 
    You cannot directly connect the coaxial cable that enters your house from a 
    cable or satellite company, the signal must pass through a tuner first. Exam
    -
    ples of tuners are digital cable boxes, VCRs, digital video recorders, and sat
    -
    ellite TV boxes. Basically, any device that can change channels is considered 
    a tuner.A composite video cable is provided with your projector so you can quickly 
    and easily connect a video source to the projector and see the amazing 
    image that is displayed. Once you have determined a more permanent loca
