IMPORTANT SERVICE SAFETY NOTES (for USA)
Ë Service 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 50k 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.

SAFETY NOTICE
Many electrical and mechanical parts in DMDTM
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.
AVIS POUR LA SECURITE
De nombreuses pièces, électriques et mécaniques, dans
les projecteur à DMDTM 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.
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
conducteur primaire dénudé. Faire attention
lors de la manipulation de cette
composante sous tension.

NOTE POUR LE PERSONNEL
D'ENTRETIEN
PRECAUTION POUR LES RADIATIONS UV
La source de lumière, la lampe UHP, dans le projecteur
LCD émet de petites quantités de radiation UV.
EVITEZ TOUTE EXPOSITION DIRECTE DES
YEUX ET DE LA PEAU.
Pour votre sécurité, nous vous prions de respecter
les points suivants:
1. Toujours porter des lunettes de soleil lors d'un entretien
du projecteur
avec la lampe allumée
et le haut du coffret retiré.
2. Ne pas faire fonctionner la lampe à l'extérieur du boîtier
de lampe.
3. Ne pas faire fonctionner plus de 2 heures avec le coffret
retiré.
Précautions pour les radiations UV
et la lampe moyenne pression
1. Toujours débrancher la fiche AC lors du remplacement
de la lampe.
2. Laisser l'unité refroidir pendant une heure avant de
procéder à l'entretien.
3. Ne remplacer qu'avec une lampe du même type. Type
AN-XR1LP, caractéristique 150W.
4. La lampe émet de petites quantités de radiation UV-
éviter tout contact direct avec les yeux.
5. La lampe moyenne pression implique un risque
d'explosion. Toujours suivre les instr uctions
d'installation décrites ci-dessous et manipuler la lampe
avec soin.
NOTE TO SERVICE
PERSONNEL
UV-RADIATION PRECAUTION

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 AN-XR1LP
rated 150W.
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.
