Zorg ervoor dat u tijdens reparatievia een polsband met weerstand verbonden bent met hetzelfdepotentiaal als de massa van het apparaat.Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.Tutti IC e parecchi semi-conduttori sono sensibili alle scarichestatiche (ESD).La loro longevit potrebbe essere fortemente ridatta in caso dinon osservazione della piø grande cauzione alla loromanipolazione. Durante le riparationi occorre quindi esserecollegato allo stesso potenziale che quello della massadelÆpparecchio 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 be restored to itsoriginal condition and that parts which are identical withthose specified be used.Safety components are marked by the symbolLe norme di sicurezza estigono che l·apparecchio vengarimesso nelle condizioni originali e che siano utilizzati ipezzi di ricambiago identici a quelli specificati.Componenty di sicurezza sono marcati conVeiligheidsbepalingen vereisen, dat het apparaat in zijnoorspronkeliijke toestand wordt teruggebracht en datonderdelen, identiek aan de gespecificeerde, worden toegepast.De Veiligheidsonderdelen zijn aangeduid met het symboolVarning !
