 (for XG-NV33XM, XG-NV330XA as well as Australian and New Zealand versions of XG-NV33XE)

Our projector uses LCD (Liqued Crystal Display) panels. These very
sophisticated panels contain 786,432 pixels (x RGB) TFTs (Thin Film
Transistors).
As with any high technology electronic equipment such as large screen TVs,
video systems and/or video cameras, there are certain acceptable tolerances
that the equipment must conform to. This unit has some inactive TFTs within
acceptable tolerances, which may result in illuminated or inactive dots on the
picture screen.

Specifications are subject to change without notice.

This will not affect the picture quality or the life expectancy of the unit.

1. Be sure to wear sun-glasses when servicing the

projector with the lamp
turned “on” and the top
enclosure removed.

2. Do not operate the lamp outside of the lamp

housing.

3. Do not operate for more than 2 hours with the

enclosure removed.

1. Be sure to disconnect the AC plug when replacing

the lamp.

2. Allow one hour for the unit to cool down before

servicing.

3. Replace only with same type lamp.  Type

CLMPF0052CE01 or BQC-XGNV2E//1 rated 85V/
120W.

4. The lamp emits small amounts of UV-Radiation,

avoid direct-eye contact.

5. The medium pressure lamp involves a risk of

explosion.  Be sure to follow installation
instructions described below and handle the lamp
with care.

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.]

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.

Reflector

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 exposurem (Fig. 1).

Note: Please obtain a lens cap before servicing a mod-

els XG-NV33XE/XM, XG-NV330XA that is re-
ceived without one.
