    First-time projector use with Windows 98The first time you connect a computer running Windows 98 to the projector, 
    the computer recognizes the projector as “new hardware” and the Add 
    New Hardware Wizard appears. Follow these instructions to use the Wiz-
    ard to load the correct driver (which was installed with your Windows 
    operating system).
    If you are running Windows 2000, Windows ME, or Window XP, skip these 
    steps and go to “Adjusting the image” on page 12.aClick Next to begin searching for the driver.bMake sure “Search for the best driver” is selected, then click Next.cUncheck any checked boxes, then click Next. Windows automatically 
    locates the driver. If this driver has been removed, reload the driver using 
    your Windows operating system CD.dWhen Windows finds the driver, you are ready to install it. Click Next.

    board). 
    The second time it detects a USB Human Interface Device (for the 
    mouse). 
    For Windows 2000, Windows ME, and Windows XP:
     The USB drivers are automatically installed.

    Connecting a video device Standard video connectionsPlug the audio/video (A/V) cable’s yellow connector into the video-out 
    connector on the video device. Plug the other yellow connector into the yel-
    low Video 2 connector on the projector. 
    Plug a white connector into the left audio out connector on the video device 
    and plug a red connector into the right audio out connector on the video 
    device. Plug the remaining white connector into the left audio in connector 
    on the projector (to the right of the yellow Video 2 connector), and plug the 
    red connector into the right audio in connector on the projector.
    Connect the black power cable to the connector on the back of the projector 
    and to your electrical outlet. 
    NOTE: Always use the power cable that shipped with the projector.Optional video connectionsIf the video device uses a round, four-prong S-video connector, plug an 
    S-video cable (sold separately) into the S-video connector on the video 
    device and into the Video 1 connector on the projector. Use the A/V cable’s 
    audio connectors as described directly above (the yellow connectors on the 
    A/V cable are not used).
    If the video device uses component cable connectors (sold separately), plug 
    the cable’s green connectors into the green component-out connector on the 
    video device and into the green component connector (labeled “Y”) on the 
    projector. Plug the component cable’s blue connectors into the blue compo-
    nent-out connector on the video device and into the blue component con-
    nector (labeled “Pb”) on the projector. Plug the component cable’s red 
    connectors into the red component-out connector on the video device and 
    into the red component connector (labeled “Pr”) on the projector. If you are 
    using RGB input, plug the additional connector into the Video 2/Synch con-
    nector and turn on the RGB Video option in the Sources menu. See page 33. 
    To connect a progressive scan EdTV or HD component source, use the Com-
    ponent to VESA adapter to connect the source.

    Shutting down the projectorThe projector automatically blanks the screen after no active source is 
    detected for 30 minutes. This blank screen helps preserve the life of the pro-
    jector. The image returns when an active source is detected or a remote or 
    keypad button is pressed.
    Screen Save
    You can make the blank screen appear after five minutes by turning on 
    Screen Save in the Settings>System menu. See page 34.
    Pow e r  S av e
    The projector also has a Power Save feature that automatically turns the 
    lamp off after no signals are detected for 5 minutes. After 3 additional min-
    utes with no signal, the projector powers down. If an active signal is 
    received before the projector powers down, the image is displayed. You 
    must press the Power button to display an image after 30 minutes have 
    passed. When Power Save is enabled, Screen Save is disabled. See page 34.
    Turning off the projector
    To turn off the projector, press the power button and verify that you want to 
    turn the projector off by pressing the power button again within 3 seconds. 
    You can cancel the shutdown by not pressing the power button a second 
    time. The lamp turns off and the LED blinks green for 1 minute while the 
    fans continue to run to cool the lamp. When the lamp has cooled, the LED 
    lights green and the fans stop. Press the power switch on the back of the 
    projector and unplug the power cable to completely power off the projector.
    Troubleshooting your setupIf your image appears correctly on the screen, skip to the next section 
    (page 25). If it does not, troubleshoot the setup. The Interactive Display and 
    LED on top of the projector indicate the state of the projector and can help 
    you troubleshoot. 
     
    The following tables show common problems. In some cases, more than one 
    possible solution is provided. Try the solutions in the order they are pre-
    sented. When the problem is solved, you can skip the additional solutions.
