SERVICE PACKAGE

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.
CF) ATTENTION
Tous les IC et beaucoup d'autres
semi-conducteurs sont sensibles aux
décharges statiques (ESD).
Leur longévité pourrait étre considérablement
écourtée par le fait qu’aucune précaution n’est
prise & leur manipulation.
Lors de réparations, s’assurer de bien &tre relié
au méme potentie! que la masse de l’appareil et
enfiler le bracelet serti d’une résistance de
sécurité.
Veiller & ce que les composants ainsi que les
outils que !’on utilise soient également a ce
potentiel.
(D> warnune
Alle [Cs und viele andere Halbleiter sind
empfindlich gegeniiber elektrostatischen
Entladungen (ESD).
Unsorgfaltige Behandlung im Reparaturfall kan
die Lebensdauer drastisch reduzieren.
Veranlassen Sie, dass Sie im Reparaturfall Uber
ein Pulsarmband mit Widerstand verbunden
sind mit dem gleichen Potential wie die Masse
des Gerates.
Bauteile und Hilfsmittel auch auf dieses gleiche
Potential halten.
CNL) 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.
Ci) awerrimeNTo
Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche (ESD).
La loro longevita potrebbe essere fortemente
ridatta in caso di non osservazione della pit
grande cauzione alla loro manipolazione.
Durante !e 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.
