    Advanced settings 
     
    TrueLife: This option refers to Faroudja’s 
    TrueLife processing of the image. All standard 
    definition interlaced video signals (composite, 
    S-video and component) are routed through 
    this processor.  Extended and High Definition 
    progressive component sources are not 
    routed though this processor by default.  You 
    can turn TrueLife on to route these signals 
    through the processor and then adjust the 
    following 2 options: 
    Chroma Detail: This adjusts the color 
    sharpness. 
    Luma Detail: This adjusts the sharpness.  
     
    Noise Reduction: adjusts signal noise 
    reduction. Choose Off to have no noise 
    reduction, choose Auto to have the software 
    determine the amount of noise reduction, or 
    choose Manual and adjust the Level.  
     
    Skintone Bypass prevents the noise reduction processing from being applied to skin tones. Images of 
    people often look better with less processing. Available when Auto or Manual are selected. 
    CCS: (Cross Color Suppression) processes the signal to remove any color information from the luma portion 
    of the signal. It is On for all composite signals, Off for all component signals, and can be turned on or off for 
    all  
    S-video signals. 
    NTSC 2:2 Pulldown: Turn this feature on to correctly display NTSC signals created from 30 frames/second 
    source material (instead of the film standard 24 frames/ second).  
    2:2/3:2 Off: Turn this feature on to turn off film mode detection. Some video material (especially film 
    animation) is difficult to distinguish from film.  
    Color Space: This option applies to computer and HDTV 
    sources (it won’t appear in the menu for 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 REC709 for component 1080i or 
    720p sources, or choose REC601 for component 480p or 
    576p sources. 
     
     
    Color Temperature: changes the intensity of the colors. Select 
    a listed value. 
     
     
      
    						
    							 
    22
    Color Control: allows you to individually adjust the gain 
    (relative warmth of the color) and the offset (the amount of black 
    in the color) of the red, green, and blue colors.  
    Gamma: Gamma tables contain preset intensity configurations 
    optimized for the input source. You can select a gamma table 
    that has been specifically tuned for either film, video, Bright 
    Room, or PC input. (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.) 
     
     
     
     
    NOTE: Your viewing preferences may vary. Cycle through 
    the gamma options and pick the one you like the best. 
     
     
     
    Video Standard: When it is set to Auto, the projector 
    attempts to pick the video standard automatically 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 Standard menu. 
    Overscan: (video sources only) removes noise around the video image. 
    The following options are for computer or HDTV sources only.  
    Phase: adjusts the phase of the video signal’s digital conversion. 
    Tracking: adjusts the frequency of the video signal’s digital conversion.  
    Horizontal/Vertical Position: adjusts the position of the source.
     
    Settings menu 
    Sources: allows you to assign a particular 
    input to a specific source key on the remote 
    and enables or disables Autosource. When 
    Autosource is not checked, the projector 
    defaults to the last-used source. If no source is 
    found, a blank screen displays. When 
    Autosource is checked, the projector checks  
     
    the last-used source first at power up. If no signal is 
    present, the projector checks the sources in order 
    until a source is found or until power down.  
     
     
     
     
     
      
    						
    							 
    23
    The Source Enable feature is used to eliminate 
    certain sources from this search, which will speed the 
    search. By default, the check boxes for all sources 
    are checked. Uncheck a source’s box to eliminate it 
    from the search. 
     
     
     
     
     
     
     
     
     
     
    System 
    All options in this menu toggle between on and off. 
    Rear: reverses the image so you can project from 
    behind a translucent screen. 
    Ceiling: turns the image upside down for ceiling-
    mounted projection. 
     
    NOTE: It is recommended that all final image adjustments in Ceiling mode are made once the unit has fully 
    warmed up (approximately 20 minutes). 
    Auto Pow er: When Auto Power is checked, the projector automatically goes into the startup state after the 
    projector receives power. This allows control of ceiling mounted projectors with a wall power switch. 
    Display Messages: displays status messages (such as “Searching”) in the lower-left corner of the screen. 
    High Power: Turn this on to increase the light output of the lamp. This also shortens lamp life and increases 
    fan noise. 
    Translucent OSD: makes the menus translucent. This prevents the image from being completely covered 
    by the menus while you are making image adjustments. 
    Chime: turn this on to hear a sound when the Power button is pressed. 
    Power Save: when On, the lamp is automatically turned 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 projector powers down, the image will be displayed.  
     
    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.  
     
      
    						
    							 
    24
    Blank Screen: determines what color displays when you press 
    the Blank button on the remote or when no source is active. 
     
     
     
     
     
    Language: allows you to select a language for the onscreen 
    display of menus and messages.

    Use these features, highlight them and press Select. 
     
    Factory Reset: restores all settings (except Lamp Hours, Ceiling, and Rear) to their default after displaying 
    a confirmation dialog box. 
    Test Pattern: displays a test pattern when the Blank button on the remote is pressed. To select the 
    patterns, use the up/down arrows on the remote or keypad. 
    Service Code: only used by authorized service personnel. 
     
    Maintenance 
    Cleaning the lens 
    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. 
    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.

    Replacing the projection lamp 
    The lamp hour timer in the About menu counts the number of hours the lamp has been in use. After 1980 
    hours, the message “Change lamp” briefly appears on the screen at each startup. To maintain optimal video 
    performance, we recommend changing the lamp after 2000 hours, depending on usage. You can order new 
    lamp modules from your dealer. 
    . 
    1. Turn off the projector and unplug the power cable.  
    2. Wait 60 minutes to allow the projector to cool thoroughly. 
    3. Turn the projector upside down and remove the lamp door by 
    removing the two screws and sliding the lamp door tabs out of 
    the three tab bays.  
     
    CAUTION: Never operate the projector with the lamp door 
    removed. This disrupts the air flow and causes the projector 
    to overheat. 
     
    4. Loosen the captive screw on the lamp module. 
     
     
    WARNINGS:  
    To avoid burns, allow the projector to cool for at least 60 minutes before you replace the lamp. 
    Do not drop the lamp module. The glass may shatter and cause injury. 
    Do not touch the glass lamp screen. Fingerprints can obscure projection sharpness. 
    Be extremely careful when removing the lamp module. In the unlikely event that the lamp ruptures, small 
    glass fragments may be generated. The lamp module is designed to contain most of these fragments, 
    but use caution when removing it. 
     
    5. Carefully remove the lamp module by grasping and lifting the metal bail wire. Dispose of the lamp in an 
    environmentally proper manner.  
    6. Install the new lamp module, making sure that it is properly seated.

    7. Tighten the single screw. 
    8. Replace the lamp door by sliding the tabs into the tab bays and tightening the two screws. 
    9. Plug in the power cable, then press the Power button to turn the projector back on. 
    10. Reset the lamp hour timer. 
    Resetting the lamp timer 
    To reset the lamp age, simultaneously holding down the two Brightness buttons on the projector’s keypad 
    for 10 seconds.  
    Using the security lock 
    The projector has a security lock for use with a PC Guardian Cable Lock System. This lock needs to be 
    order from Knoll Systems. Refer to the information that comes with the lock for instructions on how to use it.

    RS232 Terminal Specifications and Commands  
     
    To control the projector from an LCD control panel, connect an RS-232 cable to the serial control 
    connector on the projector and set your computer’s serial port settings to match this communication 
    configuration: 
     
    Command format 
    All commands consist of 3 alpha characters followed by a request, all enclosed in parentheses. The request 
    can be a read request (indicated by a “?”) or a write request (indicated by 1 to 4 ASCII digits). 
    A read request format: (AAA?) where 
      (  starts the command 
      AAA  denotes the command 
      ?  denotes the read request 
      )  ends the command 
     
    A read command returns 
    the range and the current 
    setting, for example: 
     
    A write request example: (AAA####) where 
      (  starts the command 
      AAA  denotes the command 
      ####  denotes the value to be written 
        (leading zeros not necessary) 
      )  ends the command 
    Some commands have ranges, while others are absolute. If a number greater than the maximum range is 
    received, it is automatically set to the maximum number for that function. If a command is received that is 
    not understood, a “?” is 
    returned. With absolute 
    settings, “0” is off, 1-9999 
    is on.  
    The one exception is the 
    Power command, where 0 
    is off and 1 is on.
