rLCD panel
f 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 plates 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 the built-in motor.
rLamp
The light source of the projector is a high-pressure mercury lamp.
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 lamp life varies greatly depending on individual differences and usage conditions. In particular, continuous
use for 12 hours or more and frequent off/on switching of the power greatly deteriorate the lamp and affects the
lamp life.
f In rare cases, the lamp bursts shortly after projection starts.
f The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace the
lamp unit regularly.
("When to replace the lamp unit" ( x page 141), "How to replace the lamp unit" ( x page 142))
f If the lamp bursts, gas contained inside of the lamp is released in the form of smoke.
f It is recommended that you store the Replacement lamp unit as a 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.
Disposal
To dispose of the product, ask your local authorities or dealer for correct methods of disposal.
The lamp contains mercury. When disposing of used lamp units, contact your local authorities or dealer for correct
methods of disposal.
