NOTE TO SERVICE PERSONNEL
UV-RADIATION PRECAUTlON /
The light source, metal halide lamp, in
the LCD projector emits small amounts of
UV-Radiation.
AVOID DIRECT EYE AND SKIN
EXPOSURE.
To ensure safety please adhere to the
following:
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.
UV-Radiationand Medium
Pressure Lamp Precautions
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
CLMPF0019DEOl rated 85V/25OW.
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.
iince small amounts of UV-Radiation are emitted
rom an opening between the duct cover and the
amp housing, it is recommended to place the
.ENS CAP on the opening during servicing to
rvoid eye and skin exposure (Fig. 1).
dote: Please obtain a lens cap before servicing
a model XG-3850E that is received
without one.
Figure 1.
n 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 8.
[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.

How to set up the projector and screen
Caution: When you set up the proJector
- Dd not place it in humid or dusty places, or places where the air is sooty or lull 01 cigarette smoke. II the lens, mirror,
or other optical components become dirty, the picture will blur or darken, making viewing difficult.
+ Do not expose to extreme heat or cold.
Operating temperature: 5°C to 40°C
I Position the screen so that it is not in direct sunlight or room light. Light falling directly onto the screen washes out
colors, making viewing difficult. Close the curtains and dim the lights when using the screen in a bright or sunny rM)m.
I The best picture will be obtained when the projector is at a 90 degree angle to the screen. Position the projector and
screen as shown.
