    Connecting to an External Speaker or 
    PA System
     
    Although the projector’s internal speakers are enough for 
    most small- or medium-size rooms, you can connect the 
    projector to an external speaker or public address (PA) system 
    for large rooms or to gain maximum benefit.
    To connect the projector to an external sound system, you 
    need to obtain an RCA-to-3.5 mm stereo audio cable. You 
    can get one from your computer dealer.
    1. Turn off the projector and speaker or PA system if they are 
    on.
    2. Connect the cable’s 3.5 mm stereo miniplug to the 
    projector’s Audio Out jack. 
    3. Connect the RCA plugs to the external amplified speaker 
    or PA system. Insert the cable’s red plug into the Audio R 
    jack, and the white plug into the Audio L jack.
    ¨
    Note: The internal speakers are disabled when an external 
    audio system is used.

    Turning the Equipment On and Off
    Turn on the projector and its attached equipment in the 
    following order.
    1. Video source
    2. Audio source (if different from computer or video source)
    3. Projector
    4. External speaker or PA system (if necessary)
    5. Computer
    When you turn off the equipment, do so in the reverse order.
    Turning the Projector On and Off
    1. Remove the projector lens cap.
    2. When you plug in the projector power cord, the power 
    indicator flashes orange for few seconds. Then the light 
    remains orange.
    3. Press the Power button on the remote control or 
    operation panel. The power indicator flashes green as the 
    projector warms up. When the projector is fully warmed 
    up, this light remains green.
    If computer or video equipment is attached, the computer or 
    video signal is projected.
    ¨
    Warning: Never look into the lens when the lamp is on. This can 
    damage your eyes. It is especially important that children are not 
    allowed to look into the lens.
    ¨
    Caution: When turning the projector on or off with the remote 
    control, be sure to turn the remote control on first with the power 
    switch.

    After you press the power button to turn off the projector, a
    confirmation message appears. If you want to turn off the 
    projector, press the power button again. If you don’t want to 
    turn off the projector, press any button. The fan will remain 
    on and the operation indicator will flash orange for about one 
    minute as the projector cools down.
    When the projector has cooled down, the operation indicator 
    stops flashing and remains orange.
    ¨
    Note: If you press the Power button to turn the projector back on 
    while the operation indicator is orange, there may be a delay 
    before a projected image appears.

    Focusing and Positioning the Screen 
    Image
    When an image appears on the screen, check that it is in focus 
    and correctly positioned on the screen.
    • To focus the image, rotate the focus ring (the outer ring on 
    the lens). 
    • To adjust the size of the image, rotate the inner zoom ring. 
    Rotate the zoom ring between W (wide) and T (tele) 
    marks.

    If you need to raise or lower the image on the screen, extend 
    or retract the two feet at the bottom of the projector as 
    follows:
    1. Stand behind the projector and support the front of it 
    while you lift the foot adjust levers above the feet. This 
    unlocks the feet so they can move up and down freely. Do 
    not let the projector drop.
    ¨
    Caution: Do not hold the projector by its lens. This can damage 
    the lens.
    2. While lifting the foot adjust levers, raise or lower the 
    projector until the screen image is positioned correctly.
    3. Release the lever to lock the feet in their new position.
    4. To fine-tune the height of the projector, turn the feet 
    clockwise to raise the height or anti-clockwise to lower it.

    Resize Button 
    The Resize button allows you to select the projection method 
    for certain types of image input signals from a computer.
    With images up to XGA size (1024 ´ 768) or SVGA size (800 
    x 600), you can choose from two projection methods. You 
    can either display the image in the center of the projection 
    area(Window display) or display the image full size(Resize 
    display).
    You can also choose from two projection methods with 
    images greater than XGA or SVGA size: either project a 
    portion of the image or project the entire image in a 
    compressed format. The projector automatically reduces the 
    image size to the projectors maximum resolution. The Resize 
    button cannot be used with images at XGA or SVGA 
    resolution.
    When the image source is Video, the resize button lets you 
    choose an aspect ratio either resize display or 16:9.
