INSTALLATION & SETUP

Diffused Rear Screen Systems

If the system includes a diffused rear screen, floor mount or ceiling mount the projector so that the image is directed to the center of the audience. Projection tilt should be less than 15°. See Figure 2-13.

Figure 2-13.Diffused Rear Screen Installation

In situations where the space behind the projector is limited, a mirror may be used to fold the optical path as illustrated in Figure 2-14. If a diffused screen is used, the projection angle Ø should be less than 15°. If an optical screen is used, the optical path between the mirror and the screen should be perpendicular to the screen. Much attention must be given to the position- ing of the projector and the mirror. This can be quite difficult for installers unfamiliar with this type of installation. It is recommended that your dealer or an experienced installer perform the installation.

Note: When using a mirror as shown in Figure 2-14, the calculated throw distance (D) is the summation of D1 and D2.
