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
from walls and objects. For details about the required distance from surrounding walls and
objects, refer to the operating instructions for your projector.
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.).
