Important:
Use only approved tools and test equipments. Some hand tools have handles
covered with a soft material that does not insulate you when working with live
electrical currents.
Many customers have rubber floor mats near their machines that contain small
conductive bers to decrease electrostatic discharges. Do not use such kind of mat
to protect yourself from electrical shock.

Hebrew,Italian,Japanese,andSpanish.
Safety notice 1
Before the computer is powered on after FRU replacement, make sure all screws,
springs, and other small parts are in place and are not left loose inside the computer.
Verify this by shaking the computer and listening for rattling sounds. Metallic parts
or metal akes can cause electrical shorts.
Avant de remettre l’ordinateur sous tension après remplacement d’une unité en
clientèle, vériez que tous les ressorts, vis et autres pièces sont bien en place et
bien xées. Pour ce faire, secouez l’unité et assurez-vous qu’aucun bruit suspect ne
se produit. Des pièces métalliques ou des copeaux de métal pourraient causer un
court-circuit.
Bevor nach einem FRU-Austausch der Computer wieder angeschlossen wird,
muß sichergestellt werden, daß keine Schrauben, Federn oder andere Kleinteile
fehlen oder im Gehäuse vergessen wurden. Der Computer muß geschüttelt und auf
Klappergeräusche geprüft werden. Metallteile oder-splitter können Kurzschlüsse
erzeugen.
Prima di accendere l’elaboratore dopo che é stata eettuata la sostituzione di una
FRU, accertarsi che tutte le viti, le molle e tutte le altri parti di piccole dimensioni
siano nella corretta posizione e non siano sparse all’interno dell’elaboratore.
Vericare ciò scuotendo l’elaboratore e prestando attenzione ad eventuali rumori;
eventuali parti o pezzetti metallici possono provocare cortocircuiti pericolosi.
Antes de encender el sistema despues de sustituir una FRU, compruebe que
todos los tornillos, muelles y demás piezas pequeñas se encuentran en su sitio
y no se encuentran sueltas dentro del sistema. Compruébelo agitando el sistema
y escuchando los posibles ruidos que provocarían. Las piezas metálicas pueden
causar cortocircuitos eléctricos.

Safety notice 2
DANGER
Some standby batteries contain a small amount of nickel and cadmium. Do not
disassemble a standby battery, recharge it, throw it into fire or water, or short-
circuit it. Dispose of the battery as required by local ordinances or regulations.
Use only the battery in the appropriate parts listing. Use of an incorrect battery can
result in ignition or explosion of the battery.
Certaines batteries de secours contiennent du nickel et du cadmium. Ne les
démontez pas, ne les rechargez pas, ne les exposez ni au feu ni à l’eau. Ne
les mettez pas en court-circuit. Pour les mettre au rebut, conformez-vous à la
réglementation en vigueur. Lorsque vous remplacez la pile de sauvegarde ou celle
de l’horloge temps réel, veillez à n’utiliser que les modèles cités dans la liste de
pièces détachées adéquate. Une batterie ou une pile inappropriée risque de prendre
feu ou d’exploser.
Die Bereitschaftsbatterie, die sich unter dem Diskettenlaufwerk befindet,
kann geringe Mengen Nickel und Cadmium enthalten. Sie darf nicht zerlegt,
wiederaufgeladen, kurzgeschlossen, oder Feuer oder Wasser ausgesetzt werden. Bei
der Entsorgung die örtlichen Bestimmungen für Sondermüll beachten. Beim Ersetzen
der Bereitschafts-oder Systembatterie nur Batterien des Typs verwenden, der in der
Ersatzteilliste aufgeführt ist. Der Einsatz falscher Batterien kann zu Entzündung oder
Explosion führen.
Alcune batterie di riserva contengono una piccola quantità di nichel e cadmio. Non
smontarle, ricaricarle, gettarle nel fuoco o nell’acqua né cortocircuitarle. Smaltirle
secondo la normativa in vigore (DPR 915/82, successive disposizioni e disposizioni
locali). Quando si sostituisce la batteria dell’RTC (real time clock) o la batteria di
supporto, utilizzare soltanto i tipi inseriti nell’appropriato Catalogo parti. L’impiego
di una batteria non adatta potrebbe determinare l’incendio o l’esplosione della
batteria stessa.
Algunas baterías de reserva contienen una pequeña cantidad de níquel y cadmio.
No las desmonte, ni recargue, ni las eche al fuego o al agua ni las cortocircuite.
Deséchelas tal como dispone la normativa local. Utilice sólo baterías que se
encuentren en la lista de piezas. La utilización de una batería no apropiada puede
provocar la ignición o explosión de la misma.

If the LCD breaks and the uid from inside the LCD gets into your eyes or on your
hands, immediately wash the aected areas with water at least for 15 minutes. Seek
medical care if any symptoms caused by the uid are present after washing.
Si le panneau d’achage à cristaux liquides se brise et que vous recevez dans les

Die Leuchtstoröhre im LCD-Bildschirm enthält Quecksilber. Bei der Entsorgung
die örtlichen Bestimmungen für Sondermüll beachten. Der LCD-Bildschirm
besteht aus Glas und kann zerbrechen, wenn er unsachgemäß behandelt wird
oder der Computer auf den Boden fällt. Wenn der Bildschirm beschädigt ist und
die darin befindliche Flüssigkeit in Kontakt mit Haut und Augen gerät, sollten
die betroffenen Stellen mindestens 15 Minuten mit Wasser abgespült und bei
Beschwerden anschließend ein Arzt aufgesucht werden.
Nel caso che caso l’LCD si dovesse rompere ed il liquido in esso contenuto
entrasse in contatto con gli occhi o le mani, lavare immediatamente le parti
interessate con acqua corrente per almeno 15 minuti; poi consultare un medico se i
sintomi dovessero permanere.

Safety notice 7
DANGER
Though the main batteries have low voltage, a shorted or grounded battery can
produce enough current to burn personnel or combustible materials.
Bien que le voltage des batteries principales soit peu élevé, le court-circuit ou la
mise à la masse d’une batterie peut produire susamment de courant pour brûler
des matériaux combustibles ou causer des brûlures corporelles graves.
Obwohl Hauptbatterien eine niedrige Spannung haben, können sie doch bei
Kurzschluß oder Erdung genug Strom abgeben, um brennbare Materialien zu
entzünden oder Verletzungen bei Personen hervorzurufen.
Sebbene le batterie di alimentazione siano a basso voltaggio, una batteria in
corto circuito o a massa può fornire corrente sufficiente da bruciare materiali
combustibili o provocare ustioni ai tecnici di manutenzione.
Aunque las baterías principales tienen un voltaje bajo, una batería cortocircuitada
o con contacto a tierra puede producir la corriente suciente como para quemar
material combustible o provocar quemaduras en el personal.

Important information about replacing RoHS compliant FRU
RoHS, The Restriction of Hazardous Substances in Electrical and
Electronic Equipment Directive (2002/95/EC) is a European Union legal
requirement aecting the global electronics industry. RoHS requirements
must be implemented on Lenovo products placed on the market after
June 2006. Products on the market before June 2006 are not required to
have RoHS compliant parts. If the original FRU parts are non-compliant,
replacement parts can also be non-compliant. In all cases if the original
FRU parts are RoHS compliant, the replacement part must also be RoHS
compliant.
Note:RoHSandnon-RoHSFRUpartnumberswiththesametandfunction

Single failures can occur for a variety of reasons that have nothing to do with a
hardware defect, such as cosmic radiation, electrostatic discharge, or software
errors. Consider replacing an FRU only when a problem recurs. If you suspect that
an FRU is defective, clear the error logs and run the test again. If the error does
not recur, do not replace the FRU.
