CAUTION
Setup Location
• Do not place the projector in locations that will reach high temperatures or low temperatures.
Operation ambient temperature: 0°C (32°F) to 35°C (95°F)
• Set the screen so that it is not exposed to direct sunlight or the light of direct illumination. When light
hits the screen, the screen show a white cast and will be difficult to watch.
In a bright room, the curtains should be drawn or blinds closed and the area around the screen kept
dark.
• Do not set up the projector in locations exposed to dampness, dust, greasy smoke or tobacco smoke.
Doing so will result in the adhesion of dirt to lenses, mirrors, and other optical parts and cause a degra-
dation of image quality.
• Do not place the projector in a location where the ventilation vents will be blocked or in closed areas
having poor ventilation. Doing so will cause the temperature to rise and could cause a fire or accident.
(The exhaust vents are at the front of the projector and the air intake vents are located at the side.)
• Do not place the projector at a location where it may be propped up or swayed.
• During unit operation, do not obstruct the front of the lens. During operation, strong light is projected
through the lens and if the front of the lens is obstructed by a matter or hand, it may cause fire or burn.
• During projection, be sure to remove the lens cap. The lens cap may be deformed.
• Please do not set the projector on a table or desk mat made of a heat-sensitive material. Table may be
discolored or desk mat may be deformed.
