WARNING
All ICs and many other semi-conductors are susceptible to electrostatic discharges (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set via a wrist wrap with resistance. Keep components and tools also at this potential.
F
ATTENTION
Tous les IC et beaucoup d autres semi-conducteurs sont sensibles aux d charges statiques (ESD). Leur long vit pourrait tre consid rablement
court e par le fait qu aucune pr caution n est prise leur manipulation. Lors de r parations, s assurer de bien tre reli au m me potentiel que la masse de l appareil et enfiler le bracelet serti d une r sistance de s curit . Veiller ce que les composants ainsi que les outils que l on utilise soient galement ce potentiel.

WARNUNG
Alle ICs und viele andere Halbleiter sind empfindlich gegen ber elektrostatischen Entladungen (ESD). Unsorgf ltige Behandlung im Reparaturfall kan die Lebensdauer drastisch reduzieren. Veranlassen Sie, dass Sie im Reparaturfall ber ein Pulsarmband mit Widerstand verbunden sind mit dem gleichen Potential wie die Masse des Ger tes. Bauteile und Hilfsmittel auch auf dieses gleiche Potential halten.
NL
WAARSCHUWING
Alle IC s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen verminderen. Zorg ervoor dat u tijdens reparatie via een polsband met weerstand verbonden bent met hetzelfde potentiaal als de massa van het apparaat. Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.
I
AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono sensibili alle scariche statiche (ESD). La loro longevit potrebbe essere fortemente ridatta in caso di non osservazione della pi grande cauzione alla loro manipolazione. Durante le riparazioni occorre quindi essere collegato allo stesso potenziale che quello della massa dell apparecchio tramite un braccialetto a resistenza. Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale.
Pour votre s curit , ces documents doivent tre utilis s par des sp cia­listes agr s, seuls habilit s r parer votre appareil en panne .
GB
Safety regulations require that the set be restored to its original condition and that parts which are identical with those specified, be used.
NL
Veiligheidsbepalingen vereisen, dat het apparaat bij reparatie in zijn oorspronkelijke toestand wordt teruggebracht en dat onderdelen, identiek aan de gespecificeerde, worden toegepast.
F
Les normes de s curit exigent que l appareil soit remis l tat d origine et que soient utilis s les pi ces de rechange identiques
celles sp cifi es.
D
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten. Der Original zustand des Ger ts darf nicht ver ndert werden; f r Reparaturen sind Original-Ersatzteile zu verwenden.
I
Le norme di sicurezza esigono che l apparecchio venga rimesso nelle condizioni originali e che siano utilizzati i pezzi di ricambio identici a quelli specificati.
"After servicing and before returning set to customer perform a leakage current measurement test from all exposed metal parts to earth ground to assure no shock hazard exist. The leakage current must not exceed 0.5mA."
