1. For continued safety,  no modification of any circuit

should be attempted.

2. Disconnect AC power before servicing.

Before returning the projector to the user,  perform
the following safety checks:
1. Inspect lead wires are not pinched between the chassis

and other metal parts of the projector.

2. Inspect all protective devices such as non-metallic

control knobs, insulating materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacity networks, mechanical
insulators, etc.

3. To be sure that no shock hazard exists, check for

current leakage in the following manner:

»

Plug the AC cord directly into a 120-volt AC outlet,  (Do
not use an isolation transformer for this test).

»

Using two clip leads, connect a 1.5k ohm, 10 watt
resistor paralleled by a 0.15µF capacitor in parallel
between all exposed metal cabinet parts and earth
ground.

»

Use an AC voltmeter with sensitivity of 5000 ohm per
volt.,  or higher,  sensitivity to measure the AC voltage
drop across the resistor (See Diagram).

»

All checks must be repeated with the AC plug
connection reversed.  (If necessary,  a non-polarized
adapter plug must be used only for the purpose of
completing these checks.)
Any reading of 0.3 volts RMS (this corresponds to 0.2
milliamp. AC.) or more is excessive and indicates a
potential shock hazard which must be corrected before
returning the unit to the owner.

Many electrical  and  mechanical parts in DMD™
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 this manual; electrical
components having such features are identified  by “

å

”

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 this service manual, may create shock,  fire or other
hazards.

De nombreuses pièces, électriques et mécaniques, dans
les projecteur à DMD™ présentent des caractéristiques
spéciales relatives à la sécurité,  qui ne sont souvent pas
évidentes à vue.
Le degré de protection ne peut pas être nécessairement
augmentée en utilisant des pièces de remplacement
étalonnées pour haute tension, puissance,  etc.
Les pièces de remplacement qui présentent ces
caractéristiques sont identifiées dans ce manuel;
les pièces électriques qui présentent ces particularités
sont identifiées par la marque “

å

” et hachurées dans la

liste des pièces de remplacement et les diagrammes
schématiques.  Pour assurer la protection, ces pièces
doivent être identiques à  celles  utilisées dans le circuit
d’origine.  L’utilisation de pièces qui n’ont pas les mêmes
caractéristiques que les pièces recommandées par l’usine,
indiquées dans ce manuel, peut provoquer des
électrocutions, incendies ou autres accidents.
