Cautions on use

rTo get a good picture quality
In order to view a beautiful image in higher contrast, prepare an appropriate environment. Draw curtains or blinds
over windows and turn off any lights near the screen to prevent outside light or light from indoor lamp from shining
onto the screen.
rDo not touch the surface of the projector lens with your bare hands.
If the surface of the projection lens becomes dirty from fingerprints or anything else, this will be magnified and
projected onto the screen.
It is recommended to attach the supplied lens cap to the projection lens when you do not use the projector.
rLCD panel
The LCD panel is precision-made. Note that in rare cases, pixels of high precision could be missing or always
lit. Note that such phenomena do not indicate malfunction. If still images are projected for a long time, a residual
image may remain on the LCD panel. Note that the residual image may not disappear.
rOptical parts
When the operating environment temperature is high or in environments where lots of dust, cigarette smoke, etc.
is present, the replacement cycle of the LCD panel, polarizing plate and other optical parts may be shorter even if
used for less than one year. Consult your dealer for details.
rLuminous lamp
The light source of the projector is a mercury lamp with high internal pressure.
A high-pressure mercury lamp has the following characteristics.
f The luminance of the luminous lamp will decrease by duration of usage.
f The luminous lamp may burst with a loud sound or have its service life shortened because of shock, chipping, or
degradation due to cumulative runtime.
f The life of the luminous lamp varies greatly depending on individual specificities and usage conditions. In
particular, continuous use over 12 hours and frequent switching off/on of the power greatly deteriorate the
luminous lamp and affect the luminous lamp life.
f In rare cases, the luminous lamp burst shortly after the projection.
f The risk of bursting increases when the luminous lamp is used beyond its replacement cycle. Make sure to
replace the lamp unit consistently. ("When to replace the lamp unit" (x page 118), "Replacing the lamp unit"
(x page 118))
f If the luminous lamp bursts, gas contained inside of the luminous lamp is released in a form of smoke.
f It is recommended to store replacement lamp for contingency.
rComputer and external device connections
When connecting a computer or an external device, read this manual carefully regarding the use of power cords
and shielded cables as well.
