    The projector is built with a motorized lens mount that allows for easy lens control 
    and adjustment. This includes such functions as adjusting vertical and horizontal 
    offsets, zoom and focus. The lens mount can be fitted with any one of the available 
    optional lenses – see Section 6 - Specifications.  
    • Zoom and Focus – There are two internal lens motors that allow for quick 
    motorized adjustment of zoom and focus. Adjust zoom to fit the displayed image 
    on the screen and adjust focus to improve the clarity of the image. 
    • Lens Offset – Vertical and horizontal offset is performed on the lens mount 
    through the use of DC motors.  
    • Shutter – Standard on all models the shutter allows you to turn the screen 
    absolutely black when in the “on” state. 
    • Optical Aperture – Enables adjustment of light output and contrast ratio. 
    NOTES: 1) The projection lens is shipped separately from the projector. 2) Use the 
    lens cap when transporting the projector to avoid scratching and damaging the lens, 
    which could affect your displayed image. 
    All source connections are made to the input panel located at the back of the projector. 
    Connect RGB or YPbPr sources to 
    INPUT 1, analog or digital display signals to INPUT 
    2
    , composite video to INPUT 3, and S-video to INPUT 4. Any of the available optional 
    modules can be installed in 
    INPUT 5 and/or INPUT 6. 
    There is no status display on the input panel. The only status display is part of the 
    built-in keypad located at the rear of the projector. 
    There are numerous air vents located around the projector. It is important these vents 
    remain unobstructed. Adequate airflow through the projector will prevent it from 
    overheating. 
    The two IR sensors located on the projector receive transmissions from the IR remote 
    from up to 100 feet away. It is important to keep the transmission path to these sensors 
    unobstructed for uninterrupted communications with the projector. The front IR 
    sensor is located next to the projector’s nameplate and the rear IR sensor is located at 
    the back of the projector just above the status LED display. 
    The lamp door is located at the back of the projector, which provides easy access to 
    the lamp module for replacement. See Section 4 for lamp replacement procedures.              Lens Mount &

      Laser radiation is emitted from the laser diode in the remote. Do not look 
    directly into the beam of the remote.
     
     
    The projector is typically controlled using one of the following keypads: 
    • Built-in Keypad located at the back of the projector  
    • Remote Keypad for tethered or tether-less control up to 100 feet away (includes 
    cable for use as a wired remote) 
    While each of the keypads provides complete control of the projector, they differ 
    slightly in their arrangement of keys and in what functions can be accessed directly 
    with a key press rather than requiring use of the menu system. You may find one 
    keypad more convenient than another for your specific installation and application.  
    NOTE: The remote keypad has a single IR protocol and can be converted to a wired 
    remote by connecting the cable provided with the projector to the RCA jack labeled as 
    REMOTE on the input panel.  
    To control the projector when signals from a remote keypad cannot reach the 
    projector, use the projector’s built-in keypad (Figure 3.1). The nearby LED display 
    provides feedback indicating current status and activities of the projector. Because the 
    built-in keypad has fewer keys than the remote keypad, certain projector functions are 
    accessible only 
    through the menu 
    system rather than 
    via a direct key.  
    NOTE: The built-
    in keypad cannot 
    be disabled. 
    Refer to the key descriptions provided for the IR remote – see Figure 3.2. 
    The IR remote keypad controls the projector by way of wireless communications from 
    a battery-powered infrared (IR) transmitter. Use the IR remote keypad the same way 
    you would use a remote keypad supplied with a TV or VCR. When making key 
    presses, direct the keypad either toward the screen or toward the front or rear of the 
    projector. One of the two IR sensors on the projector will detect the signals and relay 
    the commands for internal processing.

    You can convert the IR remote into a wired remote keypad using the cable provided 
    with the projector. Connect one end into the remote and the other to the mini stereo 
    connector on the input panel labeled as 
    REMOTE. The wired remote is recommended 
    when: 
    • The built-in keypad is inaccessible 
    • The lighting conditions are unsuitable for proper IR transmission 
     
    NOTE: Leave the batteries in the wired remote for the laser key (
    ) to work.  
     
    Keep in mind the following guidelines: 
    • Press keys one-at-a-time; there are no simultaneous key combinations required. 
    • Note that three keys—Power
    , Shutter Shutter and OSD OSD—are “press-and-
    hold” keys that do not function with a typical quick press-and-release key press.  
    • Hold arrow keys down for continuous adjustment/movement in one direction. In 
    serial networks, pause briefly between adjustments to ensure that more distant 
    projectors can “keep up” with the commands. 
    • If you press a key while the projector is still responding to the previous action, 
    such as during power-up, the second key press may not take effect. 
    Specific keypad commands are explained below: 
    Power ON/OFF 
    Press and hold
      for two seconds or press twice quickly to toggle the projector on 
    or off with a single keystroke. Or press and release 
     followed immediately by 
     (on) or  (off) to guarantee the correct toggle (useful if you are unsure of the 
    present state).  
    NOTES: 1) After powering down, the lamp cooling fan remains on for approximately 
    five minutes to cool the lamp. 2) It is a good idea to avoid turning a projector back on 
    until it has been off for a few minutes. Hot re-strikes of the lamp may reduce lamp life. 
    Test 
    Press 
    Te s t to step forward through all internal test patterns and this will eventually 
    lead you to the current input. If you press
    Te s tand then cycle by using the  and 
     right arrow keys, you’ll be cycling in either direction through the test patterns 
    only, no input. 
    Auto  
    Press 
    Auto to initiate an automated process in which the projector optimizes critical 
    display parameters such as size, position, pixel tracking, etc., for the current source. 
    These parameters are listed in Table 3.1. An Auto Setup can save time in perfecting a 
    display and you can modify the adjustments as desired.   Wired Remote f

    display from the other Dual SD/HD-SDI Module input. 
    Contrast 
    Press 
    Contrast to change the amount of white in your images. Use  keys until 
    you reach the desired level of contrast—for best results, start low and increase so that 
    whites remain bright but are not distorted or tinted and that light areas do not become 
    white (i.e., “crushed”). Conversely, low contrast causes dim images. See 3.5, 
    Adjusting the Image (Image Settings subsection).  
    Brightness 
    Press 
    Bright to increase or decrease the amount of black in the image. Use  
    keys until you reach the desired level of contrast—for best results, start high and 
    decrease so that dark areas do not become black (i.e., “crushed”). Conversely, overly 
    high brightness changes black to dark gray, causing washed-out images. See 3.5, 
    Adjusting the Image (Image Settings subsection). 
    Gamma 
    “Gamma” determines how gray shades are displayed between minimum input (black) 
    and maximum input (white) for a given amount of signal. The proper setting helps 
    maintain optimized blacks and whites while ensuring a smooth transition for the “in-
    between” values utilized in grays. Unlike brightness and contrast controls, the overall 
    tone of an image can be lightened or darkened without changing the two extremes and 
    your images will be more vibrant yet with good detail in dark areas when using the 
    Gamma control. 
    The normal gamma setting of 2.2 is correct for most signals and conditions. If excess 
    ambient light washes out the image and it becomes difficult or impossible to see 
    details in dark areas, lower the gamma setting to compensate. This will improve 
    contrast ratio while maintaining good details for blacks and whites
