Notes on projector placement and operation
The projector uses a high-wattage lamp that becomes very hot during operation. Please observe the
following precautions.

Never place objects on top of the projector while it is operating.
2.
Make sure there is an unobstructed space of 500 mm (19-11/16˝) or more around the projector's
exhaust openings.

If the projector is placed in a box or enclosure, ensure the temperature of the air surrounding the
projector is between 0°C/32°F and 35°C/95°F. Also make sure the projector's intake and exhaust
openings are not blocked. Take particular care to ensure that hot air from the exhaust openings is
not sucked into the intake openings.
