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 blocking of the intake and exhaust vents, maintain clearances from walls and objects
of at least 1 000 mm (3'3") for the exhaust vent and at least 500 mm (1'8") for the intake vent.
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.).
