  • Page 8: Installation Consideration

    INSTALLATION & SETUP 2.2 Installation Considerations Careful consideration should be given as to how and where the projection system is installed. Although the projector offers high performance, the final display quality could be compromised if the projector is not installed properly. This subsection discusses the considerations you should make before proceeding with a final installation.
  • Page 9 INSTALLATION & SETUP Screen Type > Screen type is a very important factor when designing a projection system. Inexperienced users or installers should always consult their dealer when deciding on screen type. The following guidelines may be helpful to understand the differences between screen types.
  • Page 10 INSTALLATION & SETUP To summarize, curved screens are better suited for brightly lit rooms where the audience is situated within the viewing cone. Flat screens are best suited when a wide viewing angle is required and ambient room lighting (near the screen) is low. Note: Screen Gain is defined in Appendix A, Glossary.
  • Page 11 INSTALLATION & SETUP Throw Distance The throw distance (projector-to-screen distance) must be determined for every new installation. Throw distance, the distance between the projector's center lens and the center of the screen, is based on screen size. As screen size increases, the distance between the projector and the screen increases.
  • Page 12 INSTALLATION & SETUP To minimize the effects caused by unwanted light from door and aisle ways, carefully choose the position of your projector and screen. Figure 2-3 shows an installation where poor screen placement has allowed too much unwanted light to enter the screen. In figure 2-4 the screen and the projector are positioned so that unwanted light is minimized.

  • Page 13: Hardware Setup

    INSTALLATION & SETUP * For rear screen applications, less space is required if a mirror is used to fold the optical path. * Choose the right screen size for your application: - As screen size increases, magnification increases which reduces brightness. This reduces the contrast ratio, which affects legibility.
  • Page 14 INSTALLATION & SETUP Follow the steps below to convert the keypad to a remote keypad and change its protocol setting. Step 1 Unplug the projector then remove the front top cover to access the built- in keypad. To remove the cover, remove the four screws holding it to the projector, two on the right and two on the left.
