Projection relationships (continued)
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.).
■ Dimensional relationship
For details on the projection distance (L), refer to "Projected image size and Projection
distance" and "Projection distance formulas" in the Appendix.
Note
z For details on "Projected image size and Projection distance" for projector models other
than the following, refer to "Setting up" in the operating instructions of the projector.
z Some of the alphabet letters at the end of projector model numbers may be omitted in this
manual.
