    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 Exit, 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. You can recall 
    these settings in the future by selecting the appropriate user presets. 
    Room Lighting: This features optimizes the projector for your room’s light-
    ing conditions. Select Dark if you are in a dark room, Light if in a bright 
    room. Choosing Light maximizes the light output from the projector.

    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 video input. 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.
    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.

    Settings menuAudio: allows adjustments to the volume, bass, treble and balance. Also 
    allows you to turn on and off Loudness (which boosts the higher and lower 
    frequencies), the Internal speakers, and projector startup Chime.
    Sources
    : allows you to assign a particular input to a specific source key 
    when using the optional Integrator remote. Also allows selection of a 
    default Startup Source and enables or disables Autosource and RGB. 
    Sources>Startup Source: this determines which source the projector 
    checks first for active video during power-up. 
    Sources>Autosource: When Autosource is not checked, the projector 
    defaults to the source selected in Startup Source. If no source is found, a 
    blank screen displays. When Autosource is checked, Startup 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. 
    Sources>RGB Video: check this box if you are using a DVD player with 
    RGB output.
    System>Rear: reverses the image so you can project from behind a translu-
    cent screen.
    Ceiling: turns the image upside down for ceiling-mounted projection.
    Auto Power: When Auto Power is checked, the projector automatically 
    goes into the startup state after the projector is powered on. This allows con-
    trol 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: (LP820 only) toggles between on and off. Turn it on to lower 
    the light output of the lamp. This also lowers the fan speed, making the pro-
    jector quieter.
    Pow e r  S av e: automatically turns the lamp off after no signals are detected 
    for 5 minutes. After 3 additional minutes with no signal, the projector pow-
    ers down. If an active signal is received before the projector 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.
    Screen Trigger : this enables the Screen Trigger connection on the connector 
    panel. See page 6 for details.
    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, highlight Capture New, then press Select twice. While the cap-
    ture is underway, the LED on the keypad turns orange. When ready, the 
    projector confirms the capture and the LED changes to green. 
    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.

    Source: cycles through the available sources.
    Auto Image: causes computer sources to be reacquired.
    Freeze: pauses the projected image.
    Zoom: Is the default effect. It lets you magnify a part of the screen. To 
    use the Zoom effect, press Effect, then press the remote’s left mouse to 
    zoom the image, press the right mouse button to decrease the magnifi-
    cation. You can use the cursor control to pan the image, displaying dif-
    ferent parts of it (only if the image is magnified). To return to the 
    original size and cancel Zoom, press the Effect button a second time.
    About: displays the About menu.
    PiP: (Picture in Picture) allows you to overlay a smaller window show-
    ing the video source on top of the larger computer source window. You 
    must have both a computer and video source connected to use PIP. You 
    can’t show a computer 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 in the menu. Press the up and down arrows to change the posi-
    tion.
