For Safe Use - Canon LH-WU350UST User Manual

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 1,400 m (4,593.2'):
Adjust projector installation settings from the menu. Failure to
adjust the settings may damage the optical parts.
• 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.
• Keep adequate clearance around your projector for its ventilation
and cooling. See figure below for the least clearance requirements.
The least clearance is a MUST when your projector is placed within a
cabinet or other closed environment.
Caution
• 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. 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.
