    Swap Main and PIP Image 
    Toggle the current picture-in-picture relationship so that the primary (main) image 
    becomes secondary (PIP), and the secondary image becomes primary. Swapping is 
    available only when PIP is enabled. 
    NOTE: There may be a slight delay when swapping the Primary and Secondary 
    images. 
    PIP Enable 
    Short cut: Press 
     on the Remote if menu not present. 
    Toggle to display from two 
    sources at once (Picture-in-
    Picture) or the primary source 
    only. This checkbox turns the 
    secondary source on and off. 
     NOTE: Disable PIP and Best 
    Switching for Interlaced 
    sources > 35kHz. 
    PIP Size and Position – 
    SUBMENU 
    Most controls in the PIP Size and 
    Position menu adjust the PIP 
    (secondary) image in the same 
    fashion as their counterparts in the 
    main Size and Position menu 
    adjust the main image—see 3.6, 
    Adjusting the Image for details. 
    Exceptions are: 
    POSITION PRESETS –Set the 
    location of the PIP (secondary) 
    image in the display. 
    ASPECT RATIO PRESETS – Choose the desired aspect ratio for your PIP pixels. Use 
    the “Default” aspect ratio when incoming format has square pixels (most common). 
    This ensures that the resulting PIP image maintains its intended aspect ratio. Use 
    “Anamorphic” for NTSC signals having narrower pixels--this will stretch the pixels 
    horizontally to regain the intended aspect ratio of the PIP image.  
    NOTE: If the image is already resized at the source it will remain that way in the PIP 
    window. If, for example, an NTSC signal is already set to anamorphic through the 
    Resize and Preset menu it will remain that way in the PIP window. If the NTSC signal 
    is formatted as widescreen at the source, then the image in the PIP window will 
    appear with black bars above and below it. 
    PIP Image Settings — 
    SUBMENU 
    Adjust the PIP (secondary image) without affecting the size or position. The primary 
    image remains unchanged. See 3.6, Adjusting the Image for details

    PIP Border Color 
    Select the desired color for the PIP window border. 
     
    NOTES: 1) Numbers 7 and 8 on the Picture-in-Picture and Switching submenu 
    control switching parameters. 2) Disable PIP in order to work with Seamless 
    Switching. 3) Disable PIP and Best Switching for Interlaced sources > 35kHz. 
     
    Seamless Switching is the ability to instantly and/or smoothly switch sources, and is 
    controlled with options 7 and 8 in the PIP and Switching menu. To use Seamless 
    Switching, PIP must be disabled. 
    Tips for best source switching:
     
    • Ensure a channel has been configured for each source. 
    • Progressive digital and analog sources are recommended. 
    • Set Image Optimization to Seamless Switching (see below). 
    • For best results, use the same frame rate and gamma setting for each. 
    NOTE: Avoid using two interlaced sources. 
    Image Optimization 
    Use this setting to choose what is more important, image quality or switching between 
    sources. Selecting Best Image Quality will ensure your image is always proper 
    however when switching sources, the screen will go blank increasing your switching 
    time. Smooth Switching allows for a cleaner transition between sources. The image 
    will fade from one image to another according to the Fade Time control. Seamless 
    Switching overrides the Frame Lock Enable settings and forces the output to run at 
    60Hz regardless of the input signal. Image is 100% seamless when switching sources.  
    NOTE: Disable PIP and Best Switching for Interlaced sources > 35kHz. 
    Fade Time 
    Set how long (in seconds) it takes to gradually dissolve one image into another for a 
    source switch when Image Optimization is set to Smooth Switching.  
    NOTE: PIP must be disabled for Fade Time to take effect. Also, the PIP window must 
    be closed to activate it.    Working with Seamless f

    Numbers Select Main Image 
    Use Numbers Select Main Image to use the numeric 
    keys #1-8 as input keys. This remapping of the keypad 
    (see right) can be particularly useful with PIP displays, 
    providing a convenient shortcut for changing the 
    primary (background) image without first having to 
    return to the Main menu. Select “Always” to use the 
    keys in this manner all of the time, even with single 
    displays. For normal keypad function, select Never 
    (default). Set to When PIP Active to activate number 
    keys only when PIP is in use. 
    NOTE: Numbers Select Main Image keypad 
    functionality works only when menus are closed. 
     
     
    Whenever you install a new lamp in the 
    projector, access the Lamp menu to record 
    the lamp serial number in the projector’s 
    memory. You can also choose a lamp mode 
    for regulating power and light output, 
    change optical aperture size, and access 
    other read-only information pertaining to 
    past and present lamps. 
    LAMP HOURS (read-only) shows the number 
    of hours logged on the current lamp. 
    Whenever you record a new lamp serial 
    number this value automatically resets to “0”, where it begins to log time for the new 
    lamp. This information also appears in the Status menu.  
     
    LAMP S/N (read-only) is the serial number recorded for the current lamp. When you 
    install a new lamp and enter its serial number, the number will appear here.  
    Enter a checkmark for 
    LAMP MESSAGE to enable a warning message that will appear 
    upon power-up when the lamp has reached the specified lamp limit and should be 
    replaced. Delete the checkmark to prevent display of this message—instead, when 
    your lamp expires, only the status display messages on the back of the projector will 
    provide the visual warning to replace the lamp. 
    NOTES: 1) It is recommended that the Lamp Message checkbox remain enabled. 2) 
    When a lamp warning message appears, press 
    Exit to temporarily cancel the 
    message. The message will continue to appear upon power-up until you install a new 
    lamp. 
    Set 
    LAMP LIMIT to the number of hours you expect to log on the current lamp before 
    replacing it. This will trigger a lamp message on-screen (if enabled). 
     
     
    3.8 Working with 
    the Lamp  
    						
    							 Section 3: Operation 
    020-100001-01 Rev. 01 (04/07)  3-55. 
    NOTES: 1) If you change modes over the life of a lamp, the lamp limit you originally 
    expected may no longer be possible. 2) Turning the lamp on and off reduces lamp life 
    significantly, as do other factors. 3) It is recommended that Lamp Limit not exceed the 
    expected lamp life, otherwise a lamp could become dangerously fragile with overuse. 
    Set which 
    LAMP MODE you want to use in order to control 
    the light output. You can choose to run the lamp as bright as 
    possible (i.e., always using maximum power—this is the 
    default upon power up) or you can power the lamp with a 
    specific wattage appropriate for the installed lamp or you can set a specific intensity 
    (brightness) to maintain. Although there are exceptions, generally higher light output 
    or higher power settings can shorten lamp life. 
    Use the lamp mode that best suits your brightness needs. For example, in a tiled 
    application you may want to precisely match brightness levels between adjacent 
    images—judge by eye and set each individual 
    Lamp Power setting as necessary. Or if 
    you want images to be as bright as possible—choose 
    Max Brightness. Always keep in 
    mind that higher lamp power settings can shorten lamp life. 
    Lamp modes are described below: 
    • 
    Max Brightness: The lamp will always burn as brightly as possible, driven by 
    100% of the power level rating for the installed lamp (see Section 6, 
    Specifications). Keep in mind that the “maximum brightness” for any lamp 
    gradually diminishes with age—images will become dimmer over time. Its current 
    output level appears in the “
    Intensity” option (not in lumens). 
    • 
    Intensity: Brightness will remain close to a specified level for as long as possible. 
    Once you select this option, enter a number representing the intensity level 
    (brightness) you wish to maintain—the projector will automatically adjust power 
    as needed to maintain this intensity as closely as possible. Note that the intensity 
    value is a correlation only and does not represent an actual lumens level. See 
    “
    Intensity” below.  
    • 
    Power: The power supplied to the lamp will remain at your specified wattage 
    level. Once you select this option, enter the number of watts representing the 
    power level you wish to maintain. See “
    Power” below. 
    POWER - This slide bar and number indicates how many 
    watts are applied to the lamp. You can apply anywhere 
    from approximately 60-65% of the maximum power intended for the installed lamp 
    up to 100% of the lamp rating. Set for the number of watts as desired, keeping in mind 
    that lower power levels produce dimmer images. When in either 
    Power or Max 
    Brightness
     modes, the power level remains constant. Specifying a maximum power 
    level here is the same as operating in 
    Max Brightness mode.  
    NOTE: Power level can be set only if the lamp is in P
    ower mode. 
    INTENSITY – This value and slide bar represents the 
    current brightness of your lamp, decreasing over time 
    when you are operating in 
    Max Brightness mode or at a specific Power level. When 
    you are operating in “
    Intensity” mode this value remains at the original “Intensity” 
    setting chosen and cannot be adjusted.   
    						
    							Section 3: Operation  
    3-56 020-100001-01 Rev. 01 (04/07) 
    NOTE: The number shown for “intensity” is not the actual lumen output, but rather a 
    correlated value only—1246 may represent 3500 lumens, for example. 
    To use “
    Intensity” mode, judge by eye (or use a meter) and set the level as desired for 
    your application. Over time, the projector will automatically increase the power 
    supplied to the lamp as needed to maintain the chosen intensity as closely as possible. 
    This mode is known as “Brightness Tracking” or “LiteLOC™”. 
    HOW LONG CAN I MAINTAIN BRIGHTNESS? Software can maintain your “Intensity” 
    setting until the required power reaches the maximum rating for the lamp. The lower 
    the setting, the longer it will take to reach this threshold and the longer you can 
    maintain the desired brightness. Keep in mind that once the lamp power reaches its 
    maximum wattage (see “
    Power”, above), this tracking is no longer possible. At this 
    point, the lamp will gradually begin to dim as usual, even though your original 
    “
    Intensity” value will still appear in the menu. To resume accurate tracking, reduce the 
    intensity setting so that the resulting “
    Power” value is less than its maximum—the 
    lower the intensity, the longer it can be maintained. 
    For example, a 1000-watt lamp can be driven at no more than 1000 watts. To produce 
    desired brightness at the screen, a new lamp would likely need less than this 
    maximum rating—perhaps 812 watts (example only). Over time, however, the lamp 
    will require more and more current in order to generate the desired light, until 
    eventually the lamp wattage reaches its 1000-watt maximum and the lamp power 
    automatically levels off. At this point, the tracking function terminates (i.e., the power 
    level stabilizes) and the lamp will begin to dim normally. Either reduce your 
    “
    Intensity” setting or replace the lamp. 
    Do not lower the “
    Intensity” so much that the corresponding “Power” value reaches its 
    minimum—the intensity setting will be inaccurate and cannot be maintained. For best 
    results in achieving uniform intensity amongst tiled images, choose an “
    Intensity” 
    setting that enables all lamps to operate at less than the maximum number of watts 
    available in your projector but high enough to keep the corresponding lamp power 
    above its minimum. See “
    Power”, above. 
    NOTES: 1) Lamps become more stable over time, thus a specific intensity is more 
    easily maintained as the lamp ages. 2) Intensity can be set only if the lamp is in 
    Intensity mode 3) Intensity cannot exceed the output of Max Brightness mode. 
    OPTICAL APERTURE -  This option is also available under the Advanced Image 
    Settings menu. See 4.6 – Adjusting the Image for details. 
    LAMP HISTORY - This read-only option lists the lamps most 
    recently installed and recorded in the projector. Lamp History 
    automatically updates whenever you record a new lamp serial 
    number—the new lamp is added to the bottom of the list. 
      
    						
    							 Section 3: Operation 
    020-100001-01 Rev. 01 (04/07)  3-57. 
    Use CHANGE LAMP to record the serial number for a newly installed lamp: 
    In the Lamp S/N window, use the number text entry keys to record the new lamp serial 
    number and press 
     again to accept the change. See Using Slide bars and Other 
    Controls if you need help entering the number. Once entered, the new lamp serial 
    number will be added to the Lamp History menu and the Lamp Hours timer will reset 
    to “0”. Lamp Mode and Lamp Limit remain as they were for the previous lamp and 
    can be changed at any time. See Figure 3.12. 
     
    Figure 3.12. Recording the New Lamp Serial Number 
    NOTE: Enter a serial number only if you have just installed a new lamp. This will 
    help ensure that lamp timer is not reset on an old lamp and that the number of hours 
    logged on the lamp will be accurate. 
    IMPORTANT: Always record the serial number of a NEW lamp. 
     
    When a new lamp is installed and its serial 
    number recorded by selecting “Change 
    Lamp” in the Lamp menu, the lamp timer 
    resets to “0” and begins logging time for 
    the new lamp. This tally appears in both 
    the Lamp menu (see right) and the Status 
    menu. 
    To review the number of hours logged for 
    previous lamps, consult the Lamp History 
    menu. 
    If the “Lamp Message” checkbox has been enabled in the Lamp menu 
    (recommended), an expiry message will appear upon power-up when the lamp has 
    reached its defined “Lamp Limit”. In addition, the LED’s next to the built-in keypad 
    will flash “LP” when lamp time has expired. The lamp should be replaced. 
    The “Lamp Limit” setting should not exceed the expected lamp life, as an old lamp 
    becomes increasingly fragile and more prone to sudden failure. See also 4.4, Lamp 
    and Filter Replacement.

    The read-only Status menu lists a variety of details about the standard and optional 
    components currently detected in the projector. Refer to the Status menu for versions 
    of hardware and software installed, the type (size) of lamp, the hours logged in total 
    and for a specific period (such as a rental period), and for your projector model name 
    and serial number. In addition, the Status menu identifies the current channel, its 
    location, its frequencies and other details. 
    Scroll the full Status menu using 
     . Use  for page up/down. 
     
    IMPORTANT:
     When working with more than two projectors, it’s important to work 
    left to right, top to bottom. 
     
    When an installation requires multiple projectors, you can use the RS232 serial ports 
    to daisy chain the units together and control the group with a single keypad or a 
    computer/controller connected to the first projector. In such a network, you can 
    choose to broadcast commands to the entire group, or use the 
    Proj key as desired to 
    limit responses to an individual projector.  
    Alternatively, you may want to add projectors to a hub on an Ethernet network. See 
    2.4, Connecting Communications for full routing details. 
    NOTE: Refer back to 3.6, Adjusting System Parameters and Advanced Controls for 
    complete information about communicating with multiple projectors. 
    In a multiple-projector wall, you will likely want to precisely match color and intensity 
    from image-to-image so that the full wall is as uniform as possible. This matching is 
    typically done in conjunction with brightness uniformity and edge blending. 
    Preliminary Calibration 
    As a final part of the manufacturing process, all primary colors in the projector are 
    precisely set to pre-established values to ensure that overall color performance is 
    optimized and is as accurate as possible. Upon installation at a site, however, lighting 
    and other environmental factors may slightly change how these colors appear on your 
    screen. While the change is negligible in most cases, you may prefer to recover the 
    originally intended color performance before trying to match colors from several 
    projectors. Or you may be renting a projector in which the colors were corrected for 
    use at its previous site, but are not ideal for yours. 
    The recommended first step in achieving such consistency is to use a color meter to 
    measure the native primary colors—red, green, blue, and white—as they appear at the 
    screen and record these as Color Primary Settings in the Service menu (password-
    protected) for each projector. On the basis of these new values, which are stored in 
    memory, each projector will then automatically calculate any necessary corrections to 
    reproduce the original factory colors under the current environmental conditions. This 
    essentially calibrates a projector to its surroundings, compensating for factors such as 
    screen type; lamp and/or ambient lighting that can alter the final color characteristics 
    on-screen, and will improve color accuracy and consistency in a group of projectors. It 
    ensures a good starting point for further customizing and matching; however, is not 
    critical for all installations.

    To return to the factory-set color primaries, such as when a projector is moved to 
    different site, you must access the Service menu (password-protected). Select the 
    “Reset to Factory Defaults?” option in the Color Primaries submenu. Then repeat the 
    calibration process describe above, if desired, and continue with matching of colors. 
    Color Adjustment Procedure 
    Once the Color Primary Settings are calibrated for the site (see above), use the Color 
    Adjustments by X,Y or Color Saturation menu to further refine each projector’s 
    fundamental colors so that the hue and intensity of each color appears the same from 
    one display to another. Once matched, you will have created a single new shared 
    range of colors or “color gamut” that all of your projectors can produce. This 
    palette—named User 1, 2, 3 or 4—can be applied or disabled for a source at any time 
    throughout a bank of adjacent displays, simplifying both the setup and maintenance of 
    a “seamless” wall. 
    1. Set up and optimize all projector settings. You can ignore color temperature, since 
    you will be redefining color performance in this procedure, but do optimize each 
    projector in every other aspect. Closely align all screen edges. 
    2. Assign projector numbers to make communications easier. Use desired keypad. 
    3. Use the same lamp mode for all projectors, and do the following: 
    • Set Select Color Adjustment to “Max Drives” 
    • Display a full white test pattern 
    • Adjust lamp power and Optical Aperture until adjacent white fields appear the 
    same brightness. 
    4. Display the Color Adjustments by X,Y menus for all projectors. Each menu shows 
    the x/y coordinates defining the “Max Drives” color gamut for this projector. Note 
    the values shown in one (any) of the displays. See Figure 3.13. Or use the “Copy 
    From” function to copy them into a “User” gamut in one projector.  
     
    Figure 3.13. Jot Down a Set of ”Max Drives” X/Y Values 
    5. In each projector, select a “User” color adjustment (1-4) to enable Color 
    Adjustments by X,Y changes. Then enter your recorded x/y values into each menu 
    (Figure 3.14).

    Figure 3.14. Copy X/Y Values into All Projectors 
    6. In each projector, judge by eye and adjust x/y coordinates slightly in the following 
    manner: 
    • To match reds, decrease “Red 
    X” until full field red screens 
    match. 
    • To match greens, decrease 
    “Green Y” until full field 
    green screens match. 
    • To match blues, increase both 
    “Blue X” and “Blue Y” until 
    full field blue screens match. 
    NOTE: For speed, enable the “Auto 
    Color Enable” checkbox. Each color coordinate you select will then automatically 
    trigger a full field display of the corresponding color. 
    Alternatively, use the Color Saturation menu for these adjustments or to fine tune. 
    NOTE: For speed, enable the “Auto Color Enable” checkbox. Each color coordinate 
    you select will then automatically trigger a full field display of the corresponding 
    color. 
    These coordinate adjustments move the three color points closer together (see below) 
    to establish a “shared” gamut attainable by all projectors in your group. Adjust only as 
    necessary to ensure that the resulting color palette is as large as possible. When done, 
    you may need to adjust lamp power slightly. 
    7. All screens should now be color-
    matched. Apply this new “User” 
    gamut to a source at any time by 
    selecting it in the “Select Color 
    Adjustment” list accessed in the 
    Advanced Image Settings menu. 
     
      
    						
    							 Section 3: Operation 
    020-100001-01 Rev. 01 (04/07)  3-61. 
    Using the Color Saturation Menu for Color Matching 
    You may prefer to use the 
    Color Saturation menu to 
    match colors across 
    multiple screens. In the 
    three Color Adjustment 
    submenus (Red, Green, 
    Blue—see right), set all 
    main values to 100 and 
    the secondary values to 0. 
    Then judge by eye and 
    adjust the slide bars as 
    needed. Note that 
    adjustments here define 
    new x/y coordinates in the 
    Color Adjustments by X,Y 
    menu. 
    For best results, use this 
    menu after doing the color 
    adjustment procedure. 
     
    WHAT IS BRIGHTNESS UNIFORMITY? When used to refine screens already matched for 
    their primary colors (see Matching Colors in Multiple Screens, above) and overall 
    light output, proper adjustment of Brightness Uniformity can create an exceptionally 
    smooth screen in which: 
    • No area of the screen appears more red, green or blue than another  
    • No area of the screen appears brighter than another 
    • Color and light output from one screen closely matches adjacent screens 
    Although the Brightness Uniformity control can be used for a stand-alone projector, it 
    is particularly useful for setting up and maintaining tiled images that form a cohesive 
    display wall in which the color “cast” and light output appear uniform throughout 
    each image as well as throughout the entire wall. The procedure provided here 
    assumes a multiple-screen application. 
     Before You Begin 
    Read through the entire procedure before attempting to adjust Brightness Uniformity 
    controls, and keep in mind the following checklist of prerequisites and guidelines:
