Cautions on use

r To get a good picture quality
f 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.
r Do 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.
Attach the supplied lens cap to the projection lens when you do not use the projector.
r LCD 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.
r Optical 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.
r Lamp
The luminous 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 lamp will decrease by duration of usage.
f The 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 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 lamp and affect the lamp life.
f In rare cases, the lamp burst shortly after the projection.
f The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace the lamp unit
consistently. ("When to replace the lamp unit"
f If the lamp bursts, gas contained inside of the lamp is released in a form of smoke.
f It is recommended to store replacement lamp for contingency.
r Computer and external device connections
f When connecting a computer or an external device, read this manual carefully regarding the use of power cords and
shielded cables as well.
