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 lamps from
shining onto the screen.
rProjection window
Do not touch the surface of the projection window with your bare hands.
If the surface of the projection window becomes dirty from fingerprints or anything else, this will be magnified and
projected onto the screen.
rLCD panel
The LCD panel is precision-made. Note that in rare cases, pixels 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. In this case, project
the all white screen for over an hour. 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.
rDo not move the projector or subject it to vibration or impact while it is operating.
Doing so may shorten the life of internal components or result in malfunctions.
rLight source
The light source of the projector uses laser diode, and has the following characteristics.
f Depending on the operating environment temperature, the luminance of the light source will decrease.
The higher the temperature becomes, the more the luminance of the light source decreases.
f The luminance of the light source will decrease by duration of usage.
If brightness is noticeably reduced and the light source does not turn on, ask your dealer to clean inside the
projector or replace the light source unit.
rComputer and external device connections
When connecting a computer or an external device, read this manual carefully regarding the use of power cords
