Installing the Projector (Cont.)
Projection Distance and Screen Size
The range of projection distances that can be focused depends on the lens unit (not supplied) to be used. When the aspect ratio of the screen is 4:3, the range is as follows and you need to install the projector within this range.
Lens type | Approximate projection distance | |
3.9 ft (1.2 m) to 25.9 ft | (7.9 m) | |
5.6 ft (1.7 m) to 40.3 ft | (12.3 m) | |
26.2 ft (8.0 m) to 280.3 ft (85.5 m) | ||
28.2 ft (8.6 m) to 276.1 ft (84.2 m) | ||
The value for projection distance is a guide (reference). The projected image size may vary depending on the manufactur- ing tolerance of the projection lens.

Screen with 4 : 3 aspect ratio
Screen with 16 : 9 aspect ratio
•For detailed relation between projection distances and projection screen sizes, refer to Appendix. The relation for both 4:3 and 16:9 are listed there.
•When adjusting the screen size, use a 4:3
•The diagonal length of a 16:9
•If the keystone is adjusted, the projected screen becomes smaller.
■Optional Lenses
This projector does not include a lens. You can select one of the optional lenses to adjust the projection distance. Please ask your dealer to buy and install the lens.
