    Using the menusTo open the menus, press the menu button on the keypad or remote. (The 
    menus automatically close after 60 seconds if no buttons are pressed.) The 
    Main menu appears. Use the arrow buttons to move up and down to high-
    light the desired submenu, then press the Select button. 
    To change a menu setting, highlight it, press Select, then use the up and 
    down arrow buttons to adjust the value, select an option using radio but-
    tons, or turn the feature on or off using check boxes. Press Select to confirm 
    your changes. Use the arrows to navigate to another setting. When your 
    adjustments are complete, navigate to Previous, then press Select to go to 
    the previous menu; press the Menu button at any time to close the menus. 
    Dots appear before the menu name. The number of dots indicate the menu’s 
    level, ranging from one (the Main menu) to four (the most nested menus). 
    The menus are grouped by usage:
     The Picture menu provides image adjustments.
     The Settings menu provides set-up type adjustments that are not 
    changed often.
     The About menu provides a read-only display of information about the 
    projector and source. 
    Certain menu items may be grayed out until a particular source is con-
    nected. For example, Sharpness is only available for video sources and will 
    be hidden when a computer source is active. Other menu items may be 
    grayed out when they are not available. For example, Brightness is grayed 
    out until an image is active.

    Presets: The provided Presets optimize the projector for displaying com-
    puter presentations, photographs, film images, and video images. (Film 
    input is material originally captured on a film camera, like a movie; video 
    input is material originally captured on a video camera, like a TV show or 
    sporting event.) You can use the preset as a starting point, then further cus-
    tomize the settings for each source. The settings you customize are saved in 
    the preset for each source. To restore the factory default settings, choose Fac-
    tory Reset in the Settings>Service menu. 
    There are also three user-definable presets. To set a preset for the current 
    source, adjust the image, then choose Save User 1, 2, or 3 in the Save Set-
    tings menu. You can recall these settings in the future by selecting the 
    appropriate user presets.

    Sharpness: (video sources only) changes the clarity of the edges of a video 
    image. Select a sharpness setting.
    Color Space: This option applies to computer and component video 
    sources. It allows you to select a color space that has been specifically tuned 
    for the input signal. When Auto is selected, the projector automatically 
    determines the standard. To choose a different setting, turn off Auto, then 
    choose RGB for computer sources, choose either SMPTE240, REC709 or 
    REC601 for component video sources.
    Color Temperature: changes the intensity of the colors. Select a listed 
    value, or select User and individually adjust the intensity of the red, green, 
    and blue colors.
    Video Standard: when set to Auto, the projector attempts to automatically 
    pick the video standard based on the input signal it receives. (The video 
    standard options may vary depending on your region of the world.) If the 
    projector is unable to detect the correct standard, the colors may not look 
    right or the image may appear “torn.” If this happens, manually select a 
    video standard by selecting NTSC, PAL, or SECAM from the Video Stan-
    dard menu. 
    Overscan: (video sources only) removes noise around the video image.
    The following 4 options are for computer sources only. 
    Phase: adjusts the horizontal phase of a computer source.
    Tr a c k i n g: adjusts the vertical scan of a computer source.
    Horizontal / Vertical Position: adjusts the position of a computer source.

    Settings menuAudio: allows adjustments to the Balance and Volume. Also allows you to 
    turn on and off the Internal speakers, and projector startup Chime.
    Sources
    : allows you to assign a particular input to a specific source key 
    when using the Integrator remote. Also allows selection of a default Startup 
    Source and enables or disables Autosource. 
    Sources>Power-up Source: this determines which source the projector 
    checks first for active signal during power-up. 
    Sources>Autosource: When Autosource is not checked, the projector 
    defaults to the source selected in Powerup Source. If no source is found, a 
    blank screen displays. When Autosource is checked, Powerup Source deter-
    mines which source the projector defaults to at power-up. If no signal is 
    present, the projector checks the sources in order until a source is found or 
    until power down. 
    System>Rear: reverses the image so you can project from behind a 
    translucent screen.
    Ceiling: turns the image upside down for ceiling-mounted projection.
    IR Receivers: turns individual IR receivers off or on to avoid environ-
    mental interference.
    Auto Power: When Auto Power is checked, the projector automatically 
    goes into the startup state after the projector is powered on. This allows 
    control of ceiling mounted projectors with a wall power switch.
    Display Messages: displays status messages (such as “Searching” or 
    “Mute”) in the lower-left corner of the screen.
    Low Power: toggles between on and off. Turn it on to lower the light out-
    put of the lamp. This also lowers the fan speed, making the projector qui-
    eter.
    NND: prevents your notebook computer from going into Screen Save 
    mode (functions only when the USB connector is plugged in).
    Pow e r  S av e: automatically turns the lamp off after no signals are 
    detected for 20 minutes. After 10 additional minutes with no signal, the 
    projector powers down. If an active signal is received before the projec-
    tor powers down, the image will be displayed.

    Screen Save: automatically blanks the screen after no signals are 
    detected for five minutes. The image returns when an active source is 
    detected or a remote or keypad button is pressed. Screen Save is disabled 
    when Power Save is enabled.
    Startup Logo: allows you to display a blank Black, White, or Blue screen 
    instead of the default screen at startup and when no source is detected. It 
    also allows you to capture and display a custom startup screen. 
    To capture a custom logo, display the image you want to capture on your 
    computer and select the Logo Capture option. From the Logo Capture 
    menu, use the Capture Position X and Capture Position Y adjustments to 
    frame the logo to be captured. Press Capture Start in the Logo Capture 
    menu. The projector will let you know if the capture was a success or a 
    failure.
    The next time you start the projector, the custom logo you captured dis-
    plays.
    Blank Screen: determines what color is displayed when you press the 
    Blank button on the remote.

    PiP: (Picture in Picture) allows you to overlay a smaller window showing 
    the video source on top of the larger computer source window. Only video 
    sources 2 and 3 (composite and S-video) support PiP. You must have both a 
    computer and video source connected to use PiP. You can’t show a com-
    puter image in the smaller PiP window, only a video image. You can select a 
    small, medium, or large window. You can also move the PiP window on the 
    screen using the PiP Position X and Y options, or the Upper left, Upper 
    Right, Lower Left, or Lower Right options in the menu. Press the up and 
    down arrows to change the position.
    Effect Key: allows you to assign a different function to the Effect button on 
    the remote to quickly and easily use the effect. Only one effect can be 
    enabled at a time. Highlight an effect and press Select to choose a different 
    one.

    MaintenanceNOTE: When you are performing maintenance activities on your projector, 
    keep in mind that you should only remove screws that are single-slot, or 
    flathead, screws. Any other type of screw, such as a phillips or star should 
    not be removed. These types of screws should only be removed by technical 
    support experts.Cleaning the lens1
    Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
    Avoid using an excessive amount of cleaner, and don’t apply the 
    cleaner directly to the lens. Abrasive cleaners, solvents or other harsh 
    chemicals might scratch the lens.
    2
    Lightly wipe the cleaning cloth over the lens in a circular motion. If you 
    don’t intend to use the projector immediately, replace the lens cap.
    Changing the lensLong throw and short throw lenses are available with your projector.1
    Turn off the projector and unplug the power cable.
    2
    Turn the projector upright with the lens facing upward and use a screw-
    driver to remove the two screws from the front bezel release holes on the 
    bottom of the projector.
    3
    Lift off the front bezel.
    4
    Gently place a flathead screwdriver into the slot on the top of the projec-
    tor (it is by the right speaker) and slide the small lever toward the right 
    speaker. The cover that protects the lens and the lamp housing pops up.

    To remove a lens, push the lever inside the lens housing and turn the 
    lens counterclockwise until it stops. Remove the lens.
    7
    To install a new lens, place it in the opening through the front of the pro-
    jector, aligning the red dot (near the base of the lens) with the red dot on 
    the projector. Turn clockwise until you feel the lens click into place.
    8
    Tighten the captive screw to the lens housing door. Place the front bezel 
    back onto the projector and replace the two screws on the bottom of the 
    projector. Replace the cover that protects the lens and the lamp housing 
    on top of the projector.
    Replacing the projection lampThe lamp hour timer in the About menu counts the number of hours the 
    lamp has been in use. Twenty hours before the specified end of the lamp’s 
    life, the message “Replace lamp” briefly appears on the projected screen. 
    After twenty additional hours, the lamp will no longer light. You can order 
    new lamp modules from your dealer. See the Accessories catalog that came 
    with the projector or visit our website for information.1
    Turn off the projector and unplug the power cable.

    Wait 60 minutes to allow the projector to cool thoroughly.
    3
    Gently place a flathead screwdriver into the slot on the top of the projec-
    tor (it is by the right speaker) and slide the small lever toward the right 
    speaker. The cover that protects the lamp housing and the lens pops up.
    The lamp module is on the right.
