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.).
