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
