WARNING
Ail iCs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
crastically.
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 aiso at this
potential.
CF) ATTENTION
Tous les IC et beaucoup d'autres
semi-conducteurs sont sensibles aux
cecnarges statiques (ESD).
Leur longevité pourrait étre considérablement
ecourtee par le fait qu'aucune precaution n'est
orise a leur manipulation.
Lors de reparations, s'assurer de bien étre relié
au méme potentiel que la masse de l'appareil et
enfiler le bracelet serti d'une résistance de
securite.
Veuler @ ce que jes composants ainsi que les
outils que l'on utilise soient également a 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.
@
Veiligneidsbepatingen vereisen, dat het apparaat in zijn oorspronkelijke
toestand wordt teruggebracht en dat onderdelen, identiek aan de
gespecificeerde worden toegepast.
©
(2) WARNUNG
Aile ICs und viele andere Haibleiter sind
empfindlich gegen elektrostatische Entladungen
(ESD).
Unsorgfaltige Behandlung bei der Reparatur
kann die Lebensdauer drastisch vermindern.
Sorgen sie dafiir, dass Sie im Reparaturfall
Uber ein Pulsarmband mit Widerstand mit dem
Massepotential des Geradtes verbunden sind.
halten Sie Bauteile und Hilfsmittel ebenfalls auf
diesem Potential.
@
Cat) 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
poisband met weerstand verbonden bent met
hetzeifde potentiaal als de massa van het
apparaat.
Houd componenten en huipmiddeten ook op
ditzelfde potentiaal.
a) AVVERTIMENTO
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 deila
massa dell’apparecchio tramite un braccialetto
a resistenza.
Assicurarsi che i componenti e anche gli utensili
con quali si lavora siano anche a questo
potenziaie.
Bei jeder Reparatur sind die geitenden Sicherheitsvorschriften zu
beachten. Der Originailzustand des Gerdats darf nicht verdndert werden
fur Reparaturen sind Original-Ersatzteile zu verwenden.
@
quelli specificati.
Le norme di sicurezza esigono che l'apparecchio venga rimesso nelle
condizioni originali e che siano utilizzati pezzi di ricambiago identici a
Les normes de sécurité exigent que l'appareil soit remis a |'état d'origine
et que soient utilisées les pieces de rechange identiques a celles
specifiées.
