This unit has some inactive pixels within acceptable tolerances which
may result in inactive dots on the picture screen. This will not affect
the picture quality or the life expectancy of the unit.
This SHARP projector uses a DMD panel. This very sophisticated
panel contains 786,432 pixels. As with any high technology electronic
equipment such as large screen TVs, video systems and video
cameras, there are certain acceptable tolerances that the equipment
must conform to.
Specifications are subject to change without notice.

DANGER !  –– Never turn the power on without the
lamp to avoid electric-shock or damage of the
devices since the stabilizer generates high voltages
at its start.
UV-RADIATION PRECAUTION (Continued)
Lamp Replacement
Note:
Since the lamp reaches a very high temperature
during units operation replacement of the lamp
should be done at least one hour after the power
has been turned off.  (to allow the lamp to cool off.)
Installing the new lamp, make sure not to touch the
lamp (bulb) replace the lamp by holding its reflector
2
.
[Use original replacement only.]
Since small amounts of UV-Radiation are emitted
from an opening between the duct cover and the
lamp housing, it is recommended to place the LENS
CAP on the opening during servicing to avoid eye
and skin exposure (Fig. 1).
Notes:
»
The internal parts of this model are cooled down
with the top panel tightly closed. If the power is
kept on for a long time with the top panel open, the
power may be turned off or the lamp may go out.
To avoid this during servicing, place the service
cover over the lamp and the cooling fan.
»
Place the lens cap over the service cover.
»
Please obtain a lens cap before servicing a model
XG-NV7XE that is received without one.
»
The color wheel is running at high speed. Do not
touch it nor bring anything nearby.
