For Safe Use
For Safe Use
Pay attention to the following points when installing or using the projector.
• Be careful of condensation.
If the projector is abruptly taken to a warmer location, or if the room
temperature rises abruptly, moisture in the air may condense on the lens or
mirror and affect projected images. In this case, wait a while and make sure
the moisture has evaporated before resuming use.
• Do not install the projector in a location where the temperature is high or low.
Doing so may cause a malfunction. Ranges for the environment of use and
storage are as follows.
• Environment of use: 0°C (32°F) to 40°C (104°F), 20% to 85% RH
• Storage temperature: -20°C (-4°F) to 60°C (140°F)
• When using the projector at altitudes above 2,300 m (7,545.8'):
Adjust projector installation settings from the menu (P147). Failure to adjust
the settings may shorten the lamp life or damage the lamp.
• Do not install the projector facing the wrong direction. Install the projector so
that it is not tilted left or right by more than 10°. Failure to do so may shorten
the lamp life or damage the lamp.
• Do not block the air intake or exhaust vents. Blocking the vents may trap
heat inside the projector, which may shorten the useful life of optical
components or other parts and damage the projector.
• Install the projector leaving at least 50 cm (1.6') between air intake/exhaust
vents and walls on each side of the projector. Leave a gap of at least 2 cm
(0.8") from the bottom of the projector. There is an air intake underneath the
projector. Failure to leave enough space may trap heat inside the projector
and damage it.
• Do not place any objects on top of the projector that may change shape or
color due to heat.
• Do not install the projector near high-voltage electrical power lines or an
electrical power source. This may cause malfunction.
• Clean the air filter regularly (P207). Dust that accumulates inside over long
periods without cleaning may eventually damage the projector or affect
picture quality.
• Afterimages may occur when the image changes after the same image has
been projected for some time. This is due to the nature of the LCD panels
and does not indicate a problem. The afterimage will dissipate after a while
during normal projection.
