Projection relationships

The dimensional relationship between the screen and the projector is shown below.
■ Dimensional relationship diagram
Note
z This diagram assumes that the size and position of the projected image will be adjusted so
that the image fills the entire screen.

Note
z The illustrations of projectors in this manual are for informational purposes only and do not
represent a specific projector model. Configurations may vary with the model.
Attention
z To prevent obstruction of the intake and exhaust vents, install the projector with a
clearance at least 500 mm (1 ft. 7 in.) from walls and objects.
If you are installing the projector in a sealed space, be sure to provide additional air
conditioning equipment and ventilation equipment. Insufficient ventilation will result in an
accumulation of heat and may activate the projector's protection circuit.
z Avoid setting up in places which are subject to sudden temperature changes, such as near
an air conditioner or lighting equipment (studio lamps, etc.).

distance" and "Projection distance formulas" in the Appendix.
