© WARNINGAll ICs and many other sem iconductors are susceptible toelectrostatic discharges (ESD). Careless handling duringrepair can reduce life drastically.

When repairing, make sure that you are connected with thesame potential as the mas s of the set via a wristband withresistance. Keep compone nts and tools at this potential.

f ATTENTIONTous les IC et bea ucoup dáutres semi-conducteurs sont

sensibles aux décharges stat iques (ESD). Leur longévi tepourrai t être considérablement écou rtée par le fai t quáucuneprécaut ion nést pr ise à leur manipulat ion.Lors de réparat ions, sássurer de bien être rel ié au m êmepotentiel que la masse de láppareil et enfileer le braceletserti dúne résistance de sécurité.

Vei l ler à ce que les composa nts ainsi que les out i ls que l ónutilise soient également à ce potentiel.

d WARNUNGAlle ICs und viele an dere Halbleiter sind empfindlichgegenüber elektrostatischen Entladungen (ESD).Unsorgfältige Behandlung im Repa raturfall kann dieLebensdauer drastisch reduzieren.Sorgen Sie dafür, daß Sie im Re paraturfall über ein Puls-armband mit Widerstand mit dem Mas sepotential desGerätes verbunden sind.Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesemPotential.

ñ WAARSCHUWINGAlle IC´s en vele andere halfgeleiders zijn gevoelig voorelectrostatische ontladingen (ESD).Onzorgvuldig behandelen tijdens reparatie kan de levensduur

drastisch doen vermindern. Zorg ervoor da t u tijdens reparatievia een polsband met weerstand verbond en bent met hetzelfdepotentiaal als de massa van het apparaat.Houd compon enten en hulpmiddelen ook op ditzelfde potentiaal.

i AVVERTIMENTOTutti IC e parecchi sem i-conduttori sono sensibili alle scarichestatiche (ESD).La loro longevità potrebbe essere fortemente ridatta in caso dinon osservazione della più grande cauzione alla loromanipolazione. Durante le riparationi occorre quindi esserecollegato allo stesso potenziale che quello della massadelápparecchio tramite un braccialetto a resistenza.Assicurarsi che i componenti e anche gli utensili con quali silavora siano anche a questo potenziale.

©Safety regulations require that the set b e restored to itsoriginal condition and that parts which are identical withthose specified be used.Safety components are marked by the symbol

iLe norme di sicurezza estigono che lápparecchio vengarimesso nelle condizioni originali e che siano utilizzati ipezzi di ricambiago identici a quelli specificati.Componenty di sicurezza sono m arcati con
