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
decharges statiques(ESD).
Leur longevite pourrait etre considerablement
ecourtee par le fait qu'aucune precaution n'est
prise a leur manipulation.
Lors de reparations,s'assurer de bien etre relie
au meme potentiel que la masse de l'appareil et
enfiler le bracelet serti d'une resistance de
securite.
Veiller a ce que les composants ainsi que les
outils que l'on utilise soient egalement ace
potentiel.

ESD
D
WARNING
Alle ICs und viele andere Halbleiter sind
empfindich gegenuber 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.
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.
AVVERTIMENTO
I
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 piu
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.
ATTENTION
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 securite exigent que I'appareil soit remis a I' etat
d'origine et que soient utilisees les pieces de rechange identiques
a celles specifiees.
D
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu
beachten.Der Original zustand des Gerats darf nicht verandert werden;
fur Reparaturen sind Original-Ersatzteile zu verwenden.
I
Le norme di sicurezza esigono che I'apparecchio venga rimesso
nelle condizioni originali e che siano utilizzati i pezzi di ricambio
identici a quelli specificati.
Pour votre securite,ces documents
