HANDLING CHIP COMPONENTS

1-1

All ICs and many other semiconductors 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 wristband with resistance. Keep components and tools at this potential.

f ATTENTION

Tous les IC et beaucoup d ´autres semi-conducteurs sont sensibles aux d écharges statiques (ESD). Leur long évite pourrait être consid érablement écourt ée par le fait qu ´aucune précaution n ést prise à leur manipulation. Lors de r éparations, s ´assurer de bien être reli é au m ême potentiel que la masse de l ´appareil et enfileer le bracelet serti d ´une r ésistance de s écurit é. Veiller à ce que les composants ainsi que les outils que l ´on utilise soient également à ce potentiel.

Safety regulations require that the set be restored to its original condition and that parts which are identical with those specified be used. Safety components are marked by the symbol

Les normes de s écurit é exigent que l`appareil soit remis à l`état d`origine et que soient utilis ées les pi èces de rechange identiques à celles sp écifiées. Les composants de s écurit é sont marqu és

d WARNUNG

Alle ICs und viele andere Halbleiter sind empfindlich gegen über elektrostatischen Entladungen (ESD). Unsorgf ältige Behandlung im Reparaturfall kann die Lebensdauer drastisch reduzieren. Sorgen Sie daf ür, daß Sie im Reparaturfall über ein Pulsarmband mit Widerstand mit dem Massepotential des Gerätes verbunden sind. Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem Potential.

Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten. Der Originalzustand des Ger ätes darf nicht ver ändert werden. F ür Reparaturen sind Originalersatzteile zu verwenden. Sicherheitsbauteile sind durch das Symbol markiert.

SAFETY

ñ WAARSCHUWING

Alle IC ´s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen vermindern. Zorg ervoor dat u tijdens reparat ie 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 scar iche statiche (ESD). La loro longevit à potrebbe essere fortemente ridatta in caso di non osservazione della pi ù grande cauzione alla loro manipolazione. Durante le riparationi occorre quindi essere collegato allo stesso potenziale che quello della massa delápparecchio tramite un braccialetto a resistenza. Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale.

Veiligheidsbepalingen vereisen, dat het apparaat in zijn oorspronkeliijke toestand wordt teruggebracht en dat onderdelen, identiek aan de gespecificeerde, worden toegepas t. De Veiligheidsonderdelen zijn aangeduid met het symbool

Le norme di sicurezza estigono che l ´apparecchio venga rimesso nelle condizioni originali e che siano utilizzati i pezzi di ricambiago identici a quelli specificati. Componenty di sicurezza sono marcati con

After servicing and before returning the set to customer perform a leakage current measurement test from all exposed metal parts to earth ground, to assure no shock hazard exists. The leakage current must not exceed 0.5mA.
