Safety information

Safety notices: multilingual translations Thesafetynotices in thissectionareprovided inEnglish,French,German, 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 flakes can cause electrical shorts. Avant de remettre lordinateur sous tension aprs remplacement dune unit en clientle, vrifiez que tous les ressorts, vis et autres pices sont bien en place et bien fixes. Pour ce faire, secouez lunit et assurez-vous quaucun bruit suspect ne se produit. Des pices mtalliques ou des copeaux de mtal pourraient causer un court-circuit. Bevor nach einem FRU-Austausch der Computer wieder angeschlossen wird, mu sichergestellt werden, da keine Schrauben, Federn oder andere Kleinteile fehlen oder im Gehuse vergessen wurden. Der Computer mu geschttelt und auf Klappergerusche geprft werden. Metallteile oder-splitter knnen Kurzschlsse erzeugen.

Prima di accendere lelaboratore dopo che stata effettuata 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 allinterno dellelaboratore. Verificare ci scuotendo lelaboratore 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 dems piezas pequeas se encuentran en su sitio y no se encuentran sueltas dentro del sistema. Comprubelo agitando el sistema y escuchando los posibles ruidos que provocaran. Las piezas metlicas pueden causar cortocircuitos elctricos.

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 dmontez pas, ne les rechargez pas, ne les exposez ni au feu ni leau. Ne les mettez pas en court-circuit. Pour les mettre au rebut, conformez-vous la rglementation en vigueur. Lorsque vous remplacez la pile de sauvegarde ou celle de lhorloge temps rel, veillez nutiliser que les modles cits dans la liste de pices dtaches adquate. Une batterie ou une pile inapproprie risque de prendre feu ou dexploser. 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 rtlichen Bestimmungen fr Sondermll beachten. Beim Ersetzen der Bereitschafts-oder Systembatterie nur Batterien des Typs verwenden, der in der Ersatzteilliste aufgefhrt ist. Der Einsatz falscher Batterien kann zu Entzndung oder Explosion fhren.

Alcune batterie di riserva contengono una piccola quantit di nichel e cadmio. Non smontarle, ricaricarle, gettarle nel fuoco o nellacqua n cortocircuitarle. Smaltirle secondo la normativa in vigore (DPR 915/82, successive disposizioni e disposizioni locali). Quando si sostituisce la batteria dellRTC (real time clock) o la batteria di supporto, utilizzare soltanto i tipi inseriti nellappropriato Catalogo parti. Limpiego di una batteria non adatta potrebbe determinare lincendio o lesplosione della batteria stessa.

Algunas bateras de reserva contienen una pequea cantidad de nquel y cadmio. No las desmonte, ni recargue, ni las eche al fuego o al agua ni las cortocircuite.

Safety notice 6

DANGER To avoid shock, do not remove the plastic cover that protects the lower part of the inverter card. Afin dviter tout risque de choc lectrique, ne retirez pas le cache en plastique protgeant la partie infrieure de la carte dalimentation. Aus Sicherheitsgrnden die Kunststoffabdeckung, die den unteren Teil der Spannungswandlerplatine umgibt, nicht entfernen.

Per evitare scosse elettriche, non rimuovere la copertura in plastica che avvolge la parte inferiore della scheda invertitore.

Para evitar descargas, no quite la cubierta de plstico que rodea la parte baja de la tarjeta invertida.

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 lev, le court-circuit ou la mise la masse dune batterie peut produire suffisamment de courant pour brler des matriaux combustibles ou causer des brlures corporelles graves. Obwohl Hauptbatterien eine niedrige Spannung haben, knnen sie doch bei Kurzschlu oder Erdung genug Strom abgeben, um brennbare Materialien zu entznden oder Verletzungen bei Personen hervorzurufen.

Sebbene le batterie di alimentazione siano a basso voltaggio, una batteria in corto circuito o a massa pu fornire corrente sufficiente da bruciare materiali combustibili o provocare ustioni ai tecnici di manutenzione.

Aunque las bateras principales tienen un voltaje bajo, una batera cortocircuitada o con contacto a tierra puede producir la corriente suficiente 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 affecting 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.
