SAFETY PRECAUTIONS

1. Before returning an instrument to the customer, al-
ways make a safety check of the entire instrument, in-

cluding, but not limited to, the following items.
a. Be sure that no built-in protective devices are

defective and/or have been defeated during
servicing. (1) Protective shields are provided on
this chassis to protect both the technician and
the customer. Correctly replace all missing pro­tective shields, including any removed for serv­icing convenience. (2) When reinstalling the
chassis and/or other assembly in the cabinet, be
sure to put back in place all protective devices,
including,but not limited to, nonmetallic control
knobs,insulating fishpapers,adjustment and
compartment covers/shields, and isolation re­sistor/capacitor networks. Do not operate this

instrument or permit it to be operated with­out all protective devices correctly installed
and functioning.

b. Be sure that there are no cabinet openings

through which an adult or child might be able to
insert their fingers and contact a hazardous volt­age. Such opening include,but are not limited to,
(1) spacing between the picture tube and the
cabinet mask, (2) excessively wide cabinet ven­tilation slots, and (3) an improperly fitted and/or
incorrectly secured cabinet back cover.

c. Leakage Current Hot Check — With the instru-

ment completely reassembled,plug the AC line
cord directly into a 240V AC outlet. (Do not use
an isolation transformer during this test.) Use a
leakage current tester or a metering system that
complies with American National Standards In­stitutes (ANSI) C101.1 Leakage Current for Ap­pliances and Underwriters Laboratories(UL)

1950. With the instrument AC switch first in the
ON position and then in the OFF position, mea­sure from a known earth ground (metal
waterpipe, conduit,etc.) to all exposed metal
parts of the instrument(antennas, handle
bracket, metal cabinet, screwheads, metallic
overlays, control shafts,etc.), especially any ex­posed metal parts that offer an electrical return
path to the chassis. Any current measured must
not exceed 3.5 milliamp. Reverse the instru­ment power cord plug in the outlet and repeat
test.ANY MEASUREMENTS NOT WITHIN

THE LIMITS SPECIFIED HEREIN INDICATE A
POTENTIAL SHOCK HAZARD THAT MUST
BE ELIMINATED BEFORE RETURNING THE
INSTRUMENT TO THE CUSTOMER.

2. Read and comply with all caution and safety-related
notes on or inside the Monitor cabinet, on the Pro­jection Monitor chassis, or on the picture tube.

3. Design Alteration Warning — Do not alter or add
to the mechanical or electrical design of this unit.
Design alterations and additions, including, but not
limited to, circuit modifications and the addition of
the items such as auxiliary audio and/or video out­put connections might alter the safety characteris­tics of this Monitor and create a hazard to the user.
Any design alterations or additions will void the
manufacturer's warranty and will make you,the
servicer,responsible for personal injury or property
damage resulting therefrom.

4. Hot Chassis Warning — a. Some

MultiSync Monitor

chassis are electrically connected directly to one
conductor of the AC power cord and may be safely
serviced without an isolation transformer only if the
AC power plug is inserted so that the chassis is
connected to the ground side of the AC power
source. To confirm that the AC power plug is in­serted correctly, with an AC voltmeter measure be­tween the chassis and a known earth ground. If a
voltage reading in excess of 1.0V is obtained, re­move and reinsert the AC power plug in the oppo­site polarity and again measure the voltage poten­tial between the chassis and a known earth ground.
b. Some

Plasma chassis normally have 85V AC

(RMS), between chassis and earth ground regard­less of the AC plug polarity. These chassis can be
safely serviced only with an isolation transformer
inserted in the power line between the receiver and
the AC power source, for both personnel and test
equipment protection. c. Some

Plasma chassis

have a secondary ground systems in addition to the
main chassis ground. This secondary ground sys­tem is not isolated from the AC power line. The two
ground system are electrically separated by insulat­ing material that must not be defeated or altered.

SAFETY PRECAUTIONS

5. Observe original lead dress. Take extra care to
assure correct lead dress in the following areas:
a. near sharp edges, b. near thermally hot parts—
be sure that leads and components do not touch
thermally hot parts, c. the AC supply, d. high volt­age, and e. antenna wiring. Always inspect in all
areas for pinched, out-of-place, or frayed wiring. Do
not change spacing between components, and be­tween components and the printed-circuit board.
Check AC power cord for damage.

6. Components,parts, and/or wiring that appear to
have overheated or are otherwise damaged should
be replaced with components, parts, or wiring that
meet original specifications. Additionally,determine
the cause of overheating and/or damage and, if
necessary, take corrective action to remove any
potential safety hazard.

PRECAUTIONS DE SECURITE

1. Avant de remettre un appareil à un client, faire

toujours d'abord un examen de sécurité de
l'appareil en entier comprenant, mais ne s'y limitant
pas les points cités ci-dessous:
a. Vérifier qu' aucun des dispositifs de protection ne

soit défectueux ou n' ait été endommagé pendant
les travaux.
(1) Les volets protecteurs sur ce châssis ont été
montés pour protéger aussi bien le technicien
que le client. Remplacer correctement tous les
volets protecteurs manquants, aussi bien que
ceux qui ont pu être enlevés pour la commodité
des travaux.
(2) Quand vous remettez le châssis ou d'autres
assemblages ensemble dans le coffret, vérifier
qu' ont été remis à leur place tous les dispositifs
de protection, comprenant mais ne s' y limitant
point, les boutons de contrôle non-métalliques,
les feuilles d'isolation, les couverture/volets de
l'ajustement et du compartiment, et l'isolation des
réseaux résistance/condensateur. Ne pas

travailler sur cet appareil ni permettre qu'y
soit effectué un travail sans que tous les
dispositifs de protection n' y soient
correctement installés fonctionnants.

b. Bien vérifier qu'il n'y ait aucune ouverture sur le

coffret qui ne puisse permettre à un adulte ou à
un enfant d'y faire pénétrer ses doigts et attraper
une décharge électrique.
De telles ouvertures comprendraient sans pour
autant s'y limiter (1) l'espace entre le tube à im­ages et le coffret de l'eppareil, (2) les espaces
excessivement ouverts pour la ventilation et (3) la
couverture arrière du coffret improprement fixée
ou incorrectement protegée.

c. Vérification de courant de fuite

L'appareil ayant été complètement réassemblé,
brancher-le à une prise de courant de 240V. (Ne pas se
servir d'un transformateur

d'isolation pendant ce
test). Se servir d'un vérificateur de courant
d'excitation ou d'un système de mesure conforme
aux normes ANSI (American National Standards
Institute) C101.1 Leakage Current for Appliances
et U. L (Underwriters Laboratories) 1950. Le bou­ton de l'appareil en position "Marche" et ensuite
en position "Arrêt", mesurer à partir d'une prise
de terre (métallique tuyauterie, conduite, etc...) à
toutes les pièces métalliques de l'appareil
exposées (antennes, poignet métalliques, coffren
métallique, tête des vis, surfaces métalliques,
traits de contrôle, etc.) surtout à toutes les pièces
métalliques exposées qui peuvent reconduire le
courant au châssis. En aucun cas, la mesure du

courant ne doit dépasser 3.5 milliamp. Inverser la
fiche de courant de l'appareil dans la prise et
répéter le test. Tout mesurage ne s'arrêtant

pas aux limites spécifiées icicomporte un ris­que de décharge électrique dangereux, qui
doit être éliminé, avant que l'appareil ne soit
remis au client.

2. Lire et respecter toutes les mises en garde et notes
de sécurité à l'intérieur ou à l'extérieur du coffret du
rétro-projecteur, sur le châssis du rétro-projecteur
ou sur le tube à images.

3. Mise en garde contre la modification du dessin

Ne pas modifier ni ajouter à la pièce mécanique ou
électrique du modèle. Des modifications ou addi­tions, comportant, mais ne s'y limitant pas, des
modifications des circuits et l'addition d'éléments
tels que des auxilliairs audio et/ou des
branchements pour la prise de vidéo, pourrait
éprouver la sécurité de ce rétro-projecteur et créer
un risque pour l'utilisateur. Tout changement ou ad­dition accomplie annulera la garantie du fabricant et
va rendre votre service d'entretien, responsable des

dommages corporels ou de biens en résultant.

4. Mise en garde contre le châssis sous tension

a. Certains châssis de rétro-projecteur sont

électriquement reliés à un conducteur du fil de
courant et ainsi peuvent ne comporter aucun ris­que sans un transformateur d'isolation seulement
si la prise de courant est branchée, de manière
que le châssis est relié à la prise de terre de la
source de courant. Pour s'assurer que la prise de
courant est correctement insérée, relever les
mesures avec un voltmètre de courant entre le
châssis et un point de prise de terre bien connu.
Si le voltage indiqué est supérieur à 1,0V,
débrancher et reinsérer la prise de courant dans
la polarité contraire et une fois de plus remesurer
le voltage potentiel entre le câssis et la prise de
terre.

2-4

PRECAUTIONS DE SECURITE

b. Certains châssis de moniteur ont habituellement

85V (RMS) entre le châssis et la prise de terre, en
fonction de la polarité de la prise de courant. Ces
châssis peuvent ne comporter aucun risque
seulement avec un transformateur d'isolation
inséré dans la ligne de puissance située entre de
rétro-projecteur et la source d'électricité, cela
pour la protection aussi bien du personnel que du
matériel de vérfication.

c. Certains châssis de rétro-projecteur ont un

système secondaire de masse en addition avec
le système principal de masse du châssis. Ce
système secondaire de masse n'est pas isolé du
courant électrique. Les deux systèmes sont
électriquement séparés par du matériel
d'isolation qu' on vérifiera bien qu'il ne soit ni
altéré ni défectueux.

5. Vérifier la couverture originale en plomb. Accorder
la plus grande attention à la couverture de plomb
notamment aux endroits ci-dessous indiqués.
a. Près des bords aigus
b. près des parties très chaudes

Vérifier que les composants et les plombs ne

touchent pas les parties très chaudes telles que:
c. l'alimentation du courant
d. la haute tension
e. Ies fils de l'antenne
Pousser l'inspection, à tous les endroits, à la recher­che des cordes pincées, déplacées ou effilochées.
Ne pas changer l'écartement entre composants, et
entre composants et le tableau de circuit imprimé.
Vérifier que le fil de conduite électrique est en bon
état.

6. Les composants, parts (pièces) et/ou fils qui ont été
trouvés surchauffés devraient être remplacés avec
les composants, pièces et fils s'y reliant avec d'autre
qui ont les mêmes spécifications que les originales.
De plus, rechercher la cause du surchauffement et/
ou des dommages et si nécessaire, prendre les
mesures propres pour prévenir tout risque potentiel.

7. Note sur sûreté de l'appareil

Beaucoup de pièce de rétro-projecteur, qu'elles
soient électriques ou mécaniques, ont des disposi­tions de sécurité qui ne sont pas toujours évidentes
d'une simple inspection visuelle et la protection
qu'elles donnent nécessairement ne pourront être
pas obtenues par les remplaçants avec des
composants aux voltages ou watts plus élevés.
Les pièces qui ont des caractéristiques particulières
de sécurité sont identifiées avec un trait marqué
sur les schémas et sont ombragés ou comportent
un trait sur la liste des pièces. L'utilisation d'un
produit substitutif qui n'aurait pas les mêmes
caractéristiques comme il est recommandé dans
ces données d'entretien pourrait provoquer une
décharge électrique, un feu, et/ou d'autres dangers.

SAFETY PRECAUTIONS

1 . Cautions for disassembly

(1) For the wall-hang type

 During handling, try to support the set
at its frame. Never touch the filter
or glass surface. Assistant personnel on the
front side should apply hands to the lower part
of the casing. [If the casing receives an impact,
the unseen side area of the module panel glass
may be broken even though the module itself does not
seem to have been broken. Therefore, support the
frame by hand in order not to drop it.]

2. The least minimum cautions for product disassembly

 Secure a working space, arranged as wide as possible.
 Prior to disassembling the set, protect the acrylic
surface with an air mat or the like.
 To prevent the thread ridges from being damaged,
use an adequate screwdriver.
 Many screws are actually used. Therefore, use
two or three containers where these screws can
be kept . Never disassemble the inner parts of the
module (pipes, etc.).
 When lifting the module from the set, two persons
should stand on both sides of the module to hold
the stable parts of the junction while they lift the
module upright. (If dust or such foreign substance
enters in between the module and the filter, moir*
or similar problems can arise. In addition, once it
enters, it is necessary to take careful measures
not to damage the contamination area while removing
contaminants.) [Please understand that the
replacement of the module may call for an air-blast
treatment (air brush) in a clean room.]
Complementary caution) In particular, if a conductive
foreign matter (such as a metallic chip) is attached
to the flexible cable of the module, there
can be danger of the occurrence of a phenomenon
like wire breakage that is caused by partition
breakdown in the module. For this reason, it
is necessary to bear in mind that the flow of air
blast should be directed only in the predetermined
direction at all times.

2-6

SAFETY PRECAUTIONS

(Notes)

The component by the name of “module” used in
this product is defined as a section that is pro­vided with a digital circuit board (including high­voltage parts) used to emit light in the glass panel
part, excluding the surface acrylic fiIter or the tem­pered glass fiIter. It must be noted that it does
never mean the glass panel part only.

(Caution) IPXXXX is installed in the MAIN PWB and the VIDEO PWB. These components are inserted in the

power line. If there is any error occurring in the circuit, these components function to prevent the
evolution of this problem to other areas. Accordingly, check whether the same voltage is generated at
both ends of each component. (In normal state, the component is internally short-circuited.) If the
same voltage is not generated, this means that the MAIN PWB is out of order. The same check is
needed also for the DSP PWB.
