SAFETY PRECAUTIONS

WARNING: The following precautions must be observed.

ALL PRODUCTS

Before any service is performed on the chassis an
isolation transformer should be inserted between the
power line and the product.

1. When replacing the chassis in the cabinet, ensure
all the protective devices are put back in place.

2. When service is required, observe the original
lead dressing. Extra precaution should be taken to
ensure correct lead dressing in any high voltage
circuitry area.

3. Many electrical and mechanical parts in
HITACHI products have special safety related
characteristics. These characteristics are often not
evident from visual inspection, nor can the
protection afforded by them necessarily be
obtained by using replacement components rated
for higher voltage, wattage, etc. Replacement
parts which have these special safety
characteristics are identified by marking with a

! on the schematics and the replacement parts
list.
The use of a substitute replacement component
that does not have the same safety characteristics
as the HITACHI recommended replacement one,
shown in the parts list, may create electrical
shock, fire, X-radiation, or other hazards.

4. Always replace original spacers and maintain lead
lengths. Furthermore, where a short circuit has
occurred, replace those components that indicate
evidence of overheating.

5. Insulation resistance should not be less than 2M
ohms at 500V DC between the main poles and
any accessible metal parts.

6. No flashover or breakdown should occur during
the dielectric strength test, applying 3kV AC or

4.25kV DC for two seconds between the main
poles and accessible metal parts.

7. Before returning a serviced product to the
customer, the service technician must thoroughly
test the unit to be certain that it is completely safe
to operate without danger of electrical shock. The
service technician must make sure that no
protective device built into the instrument by the
manufacturer has become defective, or
inadvertently damaged during servicing.

CE MARK

1. HITACHI products may contain the CE mark on
the rating plate indicating that the product
contains parts that have been specifically
approved to provide electromagnetic
compatibility to designated levels.

2. When replacing any part in this product, please
use only the correct part itemised in the parts list
to ensure this standard is maintained, and take
care to replace lead dressing to its original state,
as this can have a bearing on the electromagnetic
radiation/immunity.

PICTURE TUBE

1. The line output stage can develop voltages in
excess of 25kV; if the E.H.T. cap is required to be
removed, discharge the anode to chassis via a
high value resistor, prior to its removal from the
picture tube.

2. High voltage should always be kept at the rated
value of the chassis and no higher. Operating at
higher voltages may cause a failure of the picture
tube or high voltage supply, and also, under
certain circumstances could produce X-radiation
levels moderately in excess of design levels. The
high voltage must not, under any circumstances,
exceed 29kV on the chassis (except for projection
Televisions).

3. The primary source of X-radiation in the product
is the picture tube. The picture tube utilised for
the above mentioned function in this chassis is
specially constructed to limit X-radiation. For
continued X-radiation protection, replace tube
with the same type as the original HITACHI
approved type

4. Keep the picture tube away from the body while
handling. Do not install, remove, or handle the
picture tube in any manner unless shatterproof
goggles are worn. People not so equipped should
be kept away while picture tubes are handled

LASERS

If the product contains a laser avoid direct exposure to
the beam when the cover is open or when interlocks are
defeated or have failed.

CONSIGNES DE SECURITE

AVERTISSEMENT: vous devez respecter les précautions suivantes

POUR TOUS LES PRODUITS

Avant d’effectuer une intervention d’entretien sur le
châssis, vous devez insérer un transformateur d’isolement
entre la ligne d’alimentation électrique et le produit.

1. Lors de la remontage du châssis dans le coffret,
vérifiez que tous les dispositifs de protection sont
remis en place.

2. Lorsqu’une intervention d’entretien s’avère
nécessaire, respectez l’agencement d’origine des
conducteurs. Vous devez prendre des précautions
supplémentaires pour garantir un agencement correct
des conducteurs dans toutes les zones où des circuits
haute tension sont présents.

3. De nombreux composants électriques et mécaniques
des appareils HITACHI ont des caractéristiques
spéciales de sécurité. Bien souvent, ces
caractéristiques ne sont pas évidentes lors d’un
examen visuel et la protection qu’ils offrent n’est pas
forcément garantie si vous utilisez des composants de
rechange conçus, par exemple, pour une tension plus
élevée, une puissance plus forte. Les pièces de
rechange qui offrent des caractéristiques spéciales de
sécurité sont identifiées par un repérage comportant

le symbole ! sur les schémas et sur la
nomenclature des pièces de rechange.
L’emploi d’un composant de rechange qui ne
respecte pas les mêmes caractéristiques de sécurité
que la pièce de rechange que recommande HITACHI
et qui figure dans la nomenclature risque de
provoquer un choc électrique, un incendie, des rayons
X ou d’autres dangers.

4. Remettez toujours en place les entretoises d’origine
et respectez la longueur des conduites. En outre, à la
suite d’un court-circuit, remplacez les composants
présentant des signes de surchauffe.

5. La résistance d’isolement doit être supérieure ou
égale à 2 méga ohms à 500 V c.c. entre les pôles
principaux et des composants métalliques
accessibles, quels qu’ils soient.

6. Aucun claquage et aucune rupture ne doit se produire
pendant l’essai de résistance diélectrique à la suite de
l’application d’une tension de 3 kV c.a. ou de 4,35
kV c.c. pendant deux secondes entre les pôles
principaux et des composants métalliques
accessibles.

7. Avant de remettre au client un produit qui a fait
l’objet d’un entretien, le technicien qui s’est chargé
de cette intervention doit tester à fond cet ensemble
pour s’assurer qu’il ne présente aucun danger
opérationnel et aucun risque de choc électrique. Ce
technicien doit s’assurer qu’aucun des dispositifs de
protection intégrés à cet instrument par le fabricant
n’est défectueux ou n’a été endommagé de façon
accidentelle lors de l’entretien.

LABEL CE

1. Les produits HITACHI peuvent avoir reçu le label
CE qui figure sur la plaque signalétique pour indiquer
que cet ensemble contient des composants qui ont fait
l’objet d’une homologation spécifique de respect des
normes de compatibilité électromagnétique en
fonction de niveaux bien spécifiés.

2. Lors du remplacement d’un des composants de ce
produit, utilisez uniquement le composant correct
identifié dans la nomenclature afin de maintenir le
respect de cette norme ; en outre, vous devez
également ramener l’agencement des conducteurs à
son état d’origine car cela peut avoir une influence au
niveau des rayonnements électromagnétiques et sur la
protection contre ces rayons.

PICTURE TUBE

1. L’étage de sortie des lignes peut développer des
tensions de plus de 25 kV ; s’il faut retirer le chapeau
de protection contre les tensions extrêmement
élevées, il convient de décharger l’anode contre le
châssis par le biais d’une résistance de forte valeur
avant de déposer ce chapeau du tube image.

2. La haute tension doit toujours se maintenir à la valeur
nominale du châssis et ne pas dépasser cette dernière.
Un fonctionnement à des températures élevées peut
provoquer une défaillance du tube image ou l’entrée
d’une tension élevée. Dans certains cas, cela peut
même provoquer des rayons X d’un niveau
légèrement supérieur aux valeurs de calcul. Cette
haute tension ne doit en aucun cas dépasser 29 kV sur
le châssis (à l’exception des téléviseurs de
projection).

3. La principale source de rayons X de cet appareil est
le tube image. Le tube image employé pour assurer la
fonction susmentionnée dans ce châssis est
spécialement construit pour limiter des rayons X.
Pour maintenir cette protection contre les rayons X, il
faut remplacer le tube d’origine d’un type agréé par
HITACHI par un autre tube de même type.

4. Lors des manipulations, ne tenez jamais le tube
image contre le corps. Pendant toutes les opérations
d’installation, de dépose et de manipulation de ce
tube image, quelle que soit la méthode employée,
vous devez toujours porter des lunettes de sécurité
anti-éclatements. Les personnes qui ne portent pas ce
type de lunettes doivent se tenir à l’écart du tube
image lors de la manipulation de ce dernier.

RAYONS LASER

Si ce produit contient un rayon laser, évitez toute
exposition directe à ce faisceau lors de l’ouverture du
couvercle ou lors de l’élimination des verrouillages de
sécurité ou après défaillance de ces verrouillages.

DEUTSCH

SICHERHEITSVORKEHRUNGEN

WARNUNG: Die folgenden Vorkehrungen müssen eingehalten werden.

ALLE PRODUKTE

Bevor die Grundplatte gewartet wird, sollte ein Trenntrafo
zwischen die Netzleitung und das Produkt eingebracht
werden.

1. Wenn die Grundplatte in das Gehäuse zurückgestellt
wird, stellen Sie sicher, dass alle
Schutzvorrichtungen wieder an ihrem Ort sind.

2. Wenn Wartung erforderlich ist, halten Sie die
originale Verdrahtungsart ein. Besondere Vorsicht ist
nötig, um die korrekte Verdrahtungsart in jedem
Hochspannungsstromkreis zu gewährleisten.

3. Viele elektrische und mechanische Teile von
HITACHI Produkten haben besondere
sicherheitsbezogene Eigenschaften. Diese
Eigenschaften fallen oft nicht ins Auge, aber der
durch sie gewährte Schutz kann nicht unbedingt
erreicht werden, wenn man Ersatzteile benutzt, die
für höhere Spannung, Leistung usw. ausgelegt sind.
Ersatzteile, die diese besonderen
Sicherheitsmerkmale haben, sind in den

Prinzipskizzen und Ersatzteillisten an einem ! zu
erkennen.
Der Gebrauch von Ersatzteilen, die nicht dieselben
Sicherheitsmerkmale haben wie die empfohlenen
HITACHI Ersatzteile, wie sie in der Ersatzteilliste
aufgeführt sind, kann zu elektrischem Schlag, Feuer,
Röntgenstrahlung und anderen Gefahren führen.

4. Immer die originalen Abstandsstücke ersetzen und
die Leitungslängen beibehalten. Wo ein Kurzschluss
passiert ist, die Teile ersetzen, bei denen Überhitzung
nachzuweisen ist.

5. Der Isolierwert sollte bei 500 V Gleichstrom
zwischen den Hauptpolen und allen zugänglichen
Metallteilen nicht unter 2M Ohm liegen.

6. Bei der Prüfung auf Durchschlagsfestigkeit sollte
kein Überschlag oder Durchschlag vorkommen,
wenn zwei Sekunden lang 3 kV Wechselstrom oder
4,25 kV Gleichstrom zwischen den Hauptpolen und
allen zugänglichen Metallteilen angelegt wird.

7. Bevor das gewartete Produkt dem Kunden
zurückgegeben wird, muss der Wartungstechniker
das Gerät gründlich prüfen, um sicherzustellen, dass
es betriebssicher ist ohne das Risiko eines
elektrischen Schlages. Der Wartungstechniker muss
sicherstellen, dass keine vom Hersteller im Gerät
eingebaute Schutzvorkehrung schadhaft geworden ist
oder bei der Wartung unabsichtlich beschädigt
wurde.

CE KENNZEICHEN

1. HITACHI Produkte enthalten eventuell das CE
Kennzeichen auf dem Leistungsschild, welches
angibt, dass das Produkt Teile enthält, die eigens
zugelassen sind, um bis zu einem spezifizierten
Niveau elektromagnetische Störfreiheit zu bewirken.

2. Wenn Sie irgendein Teil in diesem Produkt ersetzen,
benutzen Sie bitte nur das korrekte Teil, das in der
Ersatzteilliste aufgeführt ist, um sicherzustellen, dass
dieser Standard eingehalten wird, und geben Sie acht,
die Verdrahtungsart in ihren ursprünglichen Zustand
zurück zu versetzen, weil das einen Einfluss auf die
elektromagnetische Abstrahlung/Störsicherheit haben
kann.

BILDRÖHRE

1. Die Leitungsausgangsstufe kann Spannungen von
mehr als 25 kV entwickeln; wenn die
Höchstspannungskappe entfernt werden muss,
entladen Sie die Anode zum Gehäuse über einen
hochohmigen Widerstand, bevor Sie sie aus der
Bildröhre entfernen.

2. Hochspannung sollte immer auf den festgelegten
Wert des Gehäuses beschränkt bleiben und nicht
mehr. Betrieb bei höherer Spannung kann zum
Versagen der Bildröhre oder zu hoher
Spannungszufuhr führen und kann unter Umständen
auch Röntgenstrahlung hervorbringen, die leicht über
dem Konstruktionsniveau liegt. Die Hochspannung
darf auf keinen Fall 29 kV am Gehäuse überschreiten
(außer bei Projektionsfernsehern).

3. Die Hauptquelle der Röntgenstrahlung im Produkt ist
die Bildröhre. Die Bildröhre, die für die oben
erwähnte Funktion in diesem Gehäuse benutzt wird,
ist eine Spezialkonstruktion zur Begrenzung der
Röntgenstrahlung. Um den Schutz vor der
Röntgenstrahlung zu behalten, ersetzen Sie bitte die
Röhre durch denselben Typ wie den ursprünglichen
von HITACHI zugelassenen.

8. Halten Sie die Bildröhre bei der Handhabung vom
Körper weg. Sie dürfen die Bildröhre nur dann
installieren, entfernen oder handhaben, wenn Sie eine
nicht splitternde Schutzbrille tragen. Personen ohne
derartigen Schutz sollten ferngehalten werden,
solange Bildröhren gehandhabt werden.

LASER

Wenn das Produkt einen Laser enthält, setzen Sie sich
keinesfalls direkt dem Strahl aus, wenn die Abdeckung
geöffnet ist oder wenn die Verriegelung versagt.

Sage Operation

TheCheetah4 is a single-chip flat panel display controller that provides the ideal interface
between industry-standard digital graphics controllers and a wide variety of LCD panels.

For conversion of input VGA signals to higher resolution outputs, the Cheetah4 uses a
sophisticated scaling algorithm that accepts programmable parameters for horizontal and
vertical interpolation or replication. A highly intelligent filter is employed to dynamically
enhance pixels to offer crisp text images and smooth graphics. The result is an appropriately
sized image with sharp text and clear graphics that takes full advantage of LCD digital
technology. Sage’s SureSync technology extracts accurate information about the resolution and
refresh rate of the input signal and synchronizes to it. Mode changes and sync losses are

10

automatically noted and adapted to. Sure-Sync allows Cheetah4 to generate very high quality
output by providing the chip with clean, crisp input signals.

The Cheetah4 contains on-chip line buffers to upscale an image, without the need for external
frame buffer memory.

On-chip gamma correction lookup tables (color translation memories) are used to enable user
programmable brightness, contrast, and gamma correction control. By color-mapping input
RGB data, the user gains full control of the picture quality of the output panel data.
