    3. Connect the other end to an electrical outlet. 
    The 
    Power light on top of the projector turns orange, indicating 
    that the projector is receiving power but not yet turned on. Wait 
    until the light stops flashing but stays orange.
    4. Turn on your computer or video source if you have not already. 
    5. Press the P 
    Power button on top of the projector to turn it on. 
    (You can also press the P 
    Power button on the remote control.)
    The projector beeps and the 
    Power light flashes green as the 
    projector warms up. The projector lamp comes on in a few 
    seconds. When the 
    Power light stops flashing, you’re ready 
    to start. 
    6. If you don’t see your image, press the 
    Source Search button on 
    the projector or remote control repeatedly until you see it.

    warning
    Never look into the lens when 
    the lamp is on. This can 
    damage your eyes, and is 
    especially dangerous for 
    children. 
    						
    							32ProjectingWhen you’re done with your presentation, shut down the projector as 
    described on page 41. Shutting down the projector correctly prevents 
    premature lamp failure and possible damage from overheating.
    Selecting the Image Source
    If you have only one device connected to the projector, the projector 
    should detect it automatically. If you have more than one device 
    connected (for example, if you’ve connected both a computer and 
    DVD player), you may have to switch between image sources. If you 
    don’t see the image you want, press one of the following buttons on 
    the remote control:
    ■Comp 1
    Press this button to move through the following options: 
    Computer 1 (Auto), Computer 1 (RGB), and Computer 1 
    (Component Video)
    .
    ■Comp 2
    Press this button to move through the following options: 
    Computer 2 (Auto), Computer 2 (RGB), Computer 2 
    (Component Video)
    .

    ■Video
    Press to select Video.
    You can also press the 
    Source Search button on the remote control 
    or projector repeatedly until the correct image is projected. If a 
    projected image fails to appear, see the next section for help.
    Once you see your image, turn to page 35 for instructions on focusing 
    and making other image adjustments.

    What To Do If You See a Blank Screen
    If you see a blank screen or a blue screen with the message No Signal 
    after turning on your computer or video source, try the following:
    ■Make sure the cables are connected correctly, as described in 
    Chapter 1.
    ■Make sure the Power light is green and not flashing and the lens 
    cap is off. 
    ■Make sure you’ve selected the correct image source; see page 32. 
    Allow a few seconds for the projector to sync up after pressing the 
    button. 
    ■Check the Signal menu to make sure the correct input source is 
    selected. See page 55.
    If you’re using a PC notebook:
    ■Hold down the Fn key and press the function key that lets you 
    display on an external monitor. It may have an icon such as   
    or it may be labelled 
    CRT/LCD. Allow a few seconds for the 
    projector to sync up after pressing it. Check your notebook’s 
    manual or online help for details. 
    On most systems, the   or 
    CRT/LCD key lets you toggle 
    between the LCD screen and the projector, or display on both at 
    the same time. 
    ■If you’re projecting from a notebook and you don’t see the same 
    image on the projection screen and computer screen, check your 
    monitor settings to make sure both the LCD screen and the 
    external monitor port are enabled. 
    From the Control Panel, open the 
    Display utility. Click the 
    Settings tab, then click Advanced. The method for adjusting 
    the settings varies by brand; you may need to click a 
    Monitor tab, 
    then make sure the external Monitor port is set as your primary 
    display and/or enabled. See your computer’s documentation or 
    online help for details.

    Adjusting the Image Shape
    The projector automatically corrects images that are distorted when 
    the projector is tilted up or down (up to a 15° tilt). The Keystone 
    window appears on the screen while the projector makes the 
    correction. If the projected image still isn’t rectangular or has a 
    “keystone” shape, do one or more of the following:
    ■If your image looks like   or  , you’ve placed the 
    projector off to one side of the screen, at an angle. Move it directly 
    in front of the center of the screen, facing the screen squarely.
    ■If your image looks like   or  , the Auto Keystone feature 
    may have been disabled or you may need to manually adjust the 
    keystone correction value. (Auto Keystone is not available when 
    you’re using ceiling or rear projection.) Follow the directions 
    below:
    ■To turn on Auto Keystone, press the Menu button on the 
    remote control. Use the  pointer button on the remote 
    control (or the arrow buttons on the projector) to select the 
    Setting menu, then press Enter. If Auto Keystone is OFF, 
    use the  pointer button to highlight this option and press 
    Enter. Select ON in the Auto Keystone window that appears 
    and press 
    Enter to save your changes. Exit the menu by 
    pressing the
     Menu button. 
    ■To manually adjust the keystone correction value, press the 
     or   buttons on the projector to correct the shape of 
    the image. After correction, your image will be slightly 
    smaller.

    							Projecting39
    You can also make keystone adjustments using the projector’s Setting 
    menu. See page 58.
    Adjusting the Brightness
    The brightness of an image depends on the source you are projecting 
    and the amount of light in the room. If the image is too bright or not 
    bright enough, here are two ways you can adjust it:
    ■Change the Brightness setting in the Image menu. See page 54.
    ■Select Low or High for the Brightness Control option in the 
    Setting menu. (See page 58.) Low brightness mode extends the 
    life of the lamp and decreases the fan noise.
    Correcting Computer Images
    If you’ve connected a computer and the image doesn’t look right, or it 
    doesn’t fit properly on the screen, press the 
    Auto button on the 
    remote control or the 
    Enter button on the projector to automatically 
    reset the projector’s tracking, sync, resolution, and position settings. 
    (You must be projecting an image for this button to have any effect.) 
    The screen turns black for a few seconds, and then the image appears 
    again. After the image reappears, it takes about three seconds for the 
    correction to take effect. Don’t press any other buttons while this is 
    happening. 
    Adjusting the Color Mode
    You may want to adjust the color mode to select a setting that is 
    appropriate for the image you’re projecting and the environment in 
    which you’re projecting it.
    If you’re projecting computer or RGB video images, the default color 
    mode is 
    Presentation, which is appropriate for presentations in 
    bright rooms. For other images, the default color mode is 
    Dynamic, 
    which optimizes video images using natural colors.
    Color Mode button
    Auto button
    note
    If the Auto Setup option in 
    the Signal menu is enabled, 
    the projector automatically 
    corrects computer images. 
    Normally you don’t have to 
    press the 
    Auto button. See 
    page 56 for details. 
    						
    							40ProjectingThe following table lists the six color modes available.  
    To change the color mode, press the 
    Color Mode button on the 
    remote control until you see the mode you want. The currently 
    selected setting appears in the upper right corner of the screen. You 
    can also use the projector menu system to change the color mode in 
    the Image menu (see page 54).
