IMPORTANT SERVICE SAFETY NOTES (for USA)
ËService work should be performed only by qualified service technicians who are
thoroughly familiar with all safety checks and servicing guidelines as follows:
WARNING
1. For continued safety, no modification of any circuit
should be attempted.
2. Disconnect AC power before servicing.
BEFORE RETURNING THE PROJECTOR:
(Fire & Shock Hazard)
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 anAC voltmeter with sensitivity of 5000 ohm per
volt., orhigher, sensitivitytomeasure theACvoltage
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
0.2milliamp.AC.) ormore isexcessive andindicates
a potential shock hazard which must be corrected
before returning the unit to the owner.

SAFETY NOTICE
Many electrical and mechanical parts in LCD Projector
have special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be
necessarilyincreasedbyusing 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
originalcircuit. Theuse of asubstitutereplacement 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.
AVIS POUR LA SECURITE
Denombreusespièces, électriques etmécaniques,dans
les projecteur à LCD présentent des caractéristiques
spéciales relatives à la sécurité, qui ne sont souvent
pas évidentes à vue.
Ledegré deprotection nepeut pasêtre 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’utilisationdepièces qui n’ontpas lesmêmes
caractéristiques que les pièces recommandées par
l’usine, indiquées dans ce manuel, peut provoquer des
électrocutions, incendies ou autres accidents.
WARNING: The bimetallic component has the primary
conductive side exposed. Be very careful in
handling this component when the power is on.
AVERTISSEMENT:La composante bimétallique dispose du

Lamp
Reflector
Comme de petites quantités de radiation UV sont
émises par une ouverture entre les ventilateurs as-
pirants, il est recommandé de placer le capuchon
de l’optique optionnelle sur l’ouverture pendant
l’entretien pour éviter une exposition des yeux et la
peau.
SincesmallamountsofUV-radiationareemittedfrom
an opening between the exhaust fans, it is recom-
mended to place the cap of the optional lens on the
opening during servicing to avoid eye and skin ex-
posure.
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.
UV-RADIATION PRECAUTION (Continued)
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
2.
[Use original replacement only.]
DANGER ! –– Ne jamais mettre sous tension sans
la lampe pour éviter un choc électrique ou des
dommages des appareils car le stabilisateur génère
de hautes tensions à sa mise en route.

Remplacement de la lampe
Remarque:
Comme la lampe devient très chaude pendant le
fonctionnement de l’unité, son remplacement ne doit
être effectué au moins une heure après avoir coupé
l’alimentation (pour permettre à la lampe de refroidir).
En installant la nouvelle lampe, s’assurer de ne pas
toucher la lampe (ampoule). Remplacer la lampe en
tenant son réflecteur 2.
