Pay attention to the following points when installing or using the projector.
Be sure to install the projector in a location where the air intake and exhaust vents
are separated from the wall by more than 50 cm (1.6'). Failure to do so could cause
a malfunction.
Do not install the projector in a location that is damp, or where there is a lot of dust,
oily smoke or tobacco smoke. Doing so could cause contamination of optical com-
ponents such as the lens and the mirror and may result in deterioration of image
quality.
Do not touch the lens with bare hands. Doing so may result in deterioration of image
quality.
If the projector is suddenly moved from a location where the temperature is low to a
location where the temperature is high, or if the temperature in the location where the
projector is installed increases suddenly, moisture in the air could cause condensa-
tion to form on the projector lens or mirror. This may cause a blurred image. Wait until
the condensation has evaporated for the image projected to return to normal.
Do not install the projector in a location where the temperature is high or low. Doing
so may cause a malfunction.

Storage temperature: -10°C to 60°C
Do not install the projector near high-voltage electrical power lines or an electrical
power source.
Do not use the projector on a soft surface such as carpet or sponge mat, etc. Doing
so could cause heat to build up inside the projector and this could result in a mal-
function.
Do not block the air intake or exhaust vents of the cooling fan. Doing so could cause
heat to build up inside the projector and may cause a malfunction.
Installing the projector in the wrong direction may cause a malfunction or accident.
