  • Page 2: The Projector

    5-language capability ◊ modular design for ease of servicing VistaGRAPHX 2500 accepts data/graphics and video input signals for projection onto flat or curved front or rear projection screens. High brightness light is generated by an ® internal 500 watt CERMAX Xenon lamp.
  • Page 3: Components

    When you receive the VistaGRAPHX 2500 your dealer will have already unpacked it, inspected it, and prepared it for use. Included with the standard projector is an IR Remote Keypad, a VistaGRAPHX 2500 Line Cord (power cord), a VistaGRAPHX 2500 User's Manual and a Warranty Registration Card.
  • Page 4: Quick Setup

    Using either the built-in or IR remote keypad, press and hold for a second to turn the projector on. The VistaGRAPHX 2500 logo will be displayed after a brief delay. Let the projector warm up for five minutes. Using either the built-in or IR remote keypad, press , or select and display the image for the source you have connected in Step 2.
  • Page 5 This subsection discusses issues you should consider before proceeding with a final installation. Even if you do not intend to use VistaGRAPHX 2500 in a fixed and permanent installation, this subsection will help you to better understand what may be done to enhance display performance.
  • Page 6 Audiences outside the viewing cone see a dimmer image. NOTE: VistaGRAPHX 2500 lenses are designed primarily for use with flat screens. However, its depth-of-field range allows the lens to be focused on curved screens as well. Focus remains sharp in the corners, however there may be significant pincushion distortion, primarily at the top of the screen.
  • Page 7 4:3. Screens with other aspect ratios are not typically specified by diagonal size. The high brightness output of VistaGRAPHX 2500 is well suited for locations where ambient lighting is less than optimum for projection; however, it is desirable that the projector be operated in an ideal projection room environment.
  • Page 8 INSTALLATION & SETUP Outside windows are undesirable in any projection room. A small crack between curtains on a sunny day can wash out a projected image. If you do have windows, make sure that window coverings are opaque and overlapping — some window coverings are designed to provide up to 100 percent blockage of outside light.
  • Page 9: Projector Position And Mounting

    INSTALLATION & SETUP the projector away from heating and/or air conditioning vents. Changes in temperature can cause drifts in the projector circuitry which may affect performance. • Keep the projector away from devices which radiate electromagnetic energy such as motors and transformers. Common sources of these are slide projectors, speakers, power amplifiers, elevators, etc.
  • Page 10 INSTALLATION & SETUP Throw distance is roughly equal to the horizontal width of the screen multiplied by the type of lens you are using (for example, if using a 3.9:1 lens, throw distance should be approximately 3.9 the screen width). Once you know your screen size, you can closely estimate how far away the projector should be, as shown in Table 2-1, or refer to Appendix E for a permanent installation.
  • Page 11 INSTALLATION & SETUP NOTES: 1) If you cannot raise or lower the image enough for your installation, or if the image becomes keystoned or exhibits uneven brightness, the projector is probably too high or low in relation to the screen. 2) Recommended offset ranges can be exceeded, however this may affect focus.
  • Page 12: Source Connections

    2.7, Leveling for details. Note that VistaGRAPHX 2500 can be rotated and mounted at any vertical angle- i.e., you can tilt the projector forwards or backwards as much as desired for your application.
  • Page 13 The RGB input (DAT 1) includes BNC type connectors for connection to a variety of RGB sources. Such sources include VGA, SVGA, XGA, Mac, PowerMac, DEC, Sun, SGI and others. VistaGRAPHX 2500 supports multiple sync types: sync-on-green for data, composite, and separate H & V.

  • Page 16: Operating Orientation

    Do not unplug the projector in order to power down. Operating VistaGRAPHX 2500 is set up at the factory for use in a front screen, floor mount Orientation orientation. If the installation is ceiling mount or rear screen, you may notice that displayed images are upside down and/or reversed.
  • Page 17: Zoom, Focus & Vertical Offset

    INSTALLATION & SETUP Zoom, Focus & Once the VistaGRAPHX 2500 is properly set up and projecting an image on Vertical Offset screen, you are ready to make quick manual display adjustments. If you are using a zoom lens, turn the outer shell of the lens barrel to decrease or increase the size of the image at the current throw distance.

Press = Protocol "A" Press = Protocol "B" NOTE: If you change any keypad to a new protocol and the projector stops responding, the projector may be set to a conflicting protocol.
  • Page 24: Overview

    Overview This section explains how to use the VistaGRAPHX 2500 projector once it has been installed. Please read through these pages before using the projector for the first time. An understanding of VistaGRAPHX 2500 features and how to access them will help you to take full advantage of the capabilities of the projector within minutes.
