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.

ATTENTION
Tous les IC et beaucoup d’autres semi-conducteurs sont
sensiblesauxdéchargesstatiques(ESD).Leurlongévitépourrait

n’est prise à leur manipulation.
Lors de réparations, s’assurer de bien être relié au même
potentiel que la masse de l’appareil et enfiler le bracelet serti
d’une résistance de sécurité.
Veiller à ce que les composants ainsi que les outils que l’on
utilise soient également à ce potentiel.

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.

AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono sensibili alle scariche
statiche (ESD).
La loro longevità potrebbe essere fortemente ridatta in caso di
non osservazione della più grande cauzione alla loro
manipolazione.

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 sécurité, ces documents doivent être utilisés
