E-15
Please use the following diagrams to determine the screen display size and the type of screen required for any given
projector location.
Projection distances that will be in focus will be 1.3 m (4.3 feet) to 11.3 m (37.0 feet) from the front of the lens. Please
arrange the setup within this range.
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
degradation 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 acci-
dent. (The exhaust vents are at the front of the projector and the air intake vents are located at the
side.)
