Installing the Projector (Cont.)
Projection Distances and Screen Sizes
Lenses that can be used are a 3 : 1 ~ 7 : 1 zoom lens and a 1.5 : 1 fixed-focus lens. With a zoom lens used, you have a wider
latitude in selecting projection distance and installation space than with a fixed lens.
For how to install the lens, consult the dealer who installed and adjusted your projector or service center.

In the shaded areas in the above graph, the projected image may be partially distorted or
missed out depending on the distance between the projector and the screen. To project an image
with no image distortion or missing, we recommend you to use the projector in the areas defined
with solid lines in the graph.
