Cautions on use
In order to get the picture quality
J
Draw curtains or blinds over windows and turn off any lights near the screen to prevent outside light or light
z
from indoor lamps from shining onto the screen.
Depending on where the projector is used, heated air from an exhaust port or warm or cold air from an air
z
conditioner can cause a shimmering effect on screen.
Avoid use in locations where exhaust or streams of air from projector, other devices and air conditioners
ow between the projector and the screen.
The lens of projector is affected by the heat from the luminous source. Because of this, the focusing may
z
not be stable right after the power is turned on. Focusing is stabled after projecting image for 30 minutes
and longer.
Do not touch the surface of the projection lens with your bare hand.
J
If the surface of the projection lens becomes dirty from ngerprints or anything else, this will be magnied and
projected onto the screen.
DLP chips
J
The DLP chips are precision-made. Note that in rare cases, pixels of high precision could be missing or
z
always lit, but this is not a malfunction.
Directing a high power laser beam onto the projection window surface can damage the DLP chips.
z
Optical components
J
Operating the projector in an environment with high temperature or heavy exposure to dust or tobacco smoke
will reduce the service life of the optical components and may necessitate their replacement within less than
one year of use. For details, consult your dealer.
Lamp

The luminous source of the projector is a mercury lamp with high internal pressure.
A high pressure mercury lamp has following characteristics.
The brightness of the lamp will decrease by duration of usage.

z
The life of the lamp varies greatly depending on individual specicities and usage conditions. In particular,
z
continuous use over 22 hours and frequent on/off switching of the power greatly deteriorate the lamp and
affect the lamp life.
In rare cases, the lamp burst shortly after the projection.
z
The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace
z
the lamp unit consistently. (
