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 degrees. See Figure 2-13.
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 0
should be less than 15 degrees. 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 positioning 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.
