Many electrical and mechanical parts in Projector have special safety-related characteristics.
These characteristics are often not evident from visual inspection, nor can protection afforded
by them be necessarily increased by using replacement components rated for higher voltage,
wattage, etc.
Replacement parts which have these special safety characteristics are identified in the

service manual; electrical components having such features are identified by 

 and

shaded areas in the Replacement Parts Lists and Schematic Diagrams. For continued
protection, replacement parts must be identical to those used in the original circuit. The use of
a substitute replacement parts which do not have the same safety characteristics as the
factory recommended replacement parts shown in the service manual, may create shock, fire
or other hazards.

The light source, metal halide lamp, in the 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 UV protective 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-Radiation and 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 BQCXGV10WU/1 rated 100V/200W.
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 in the Lamp Replacement Procedure 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 stabiliser generates high voltages at its start.

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.
