Installation
■ Projection Distance and Image Size
Use the following diagrams to determine the exact image size and what screen is required
for any given projection distance.
• The focal range is 1.43m (56.3") to 14.86m (585") from the lens. You must install your
projector within this projection distance range.
CAUTION
Installation location
• Do not install your projector where excessively hot or cold. The ambient temperature should be within the range of
0
°C to 35°C (32° to 95°F).
• Position your projector so the sunlight or other bright light source does not strike the screen directly. If sunlight or
other bright light strikes the screen directly, the image will appear white and difficult to see.
If you are using your projector in a brightly lit room, draw the curtains or blinds to darken the area around the
screen.
• Do not install your projector where it will be subject to excessive humidity, dust, soot, or tobacco smoke.
Image quality will deteriorate if dirt builds up on the optical components such as the lenses and mirrors.
• Do not install your projector where the air vents may become obstructed or there is poor air flow. A rise in
temperature may result in fire and damage. (Note that air vents are located at the bottom and on the right side.)
