HANDLING CHIP COMPONENTS

1-6

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 sensibles aux

décharges statiques (ESD).

Leur longévité pourrait être considérablement

écourtée par le fait qu’aucune précaution 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.

ESD

WARNUNG

Alle ICs und viele andere Halbleiter sind

empfindlich gegenüber elektrostatischen

Entladungen (ESD).

Unsorgfältige Behandlung im Reparaturfall kan

die Lebensdauer drastisch reduzieren.

Veranlassen Sie, dass Sie im Reparaturfall über

ein Pulsarmband mit Widerstand verbunden

sind mit dem gleichen Potential wie die Masse

des Gerätes.

Bauteile und Hilfsmittel auch auf dieses gleiche

Potential halten.

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

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.

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.

“Pour votre sécurité, ces documents

doivent être utilisés par des spécia-

listes agréés, seuls habilités à réparer

votre appareil en panne”.

Safety regulations require that the set be restored to its original

condition and that parts which are identical with those specified,

be used.

Veiligheidsbepalingen vereisen, dat het apparaat bij reparatie in

zijn oorspronkelijke toestand wordt teruggebracht en dat onderdelen,

identiek aan de gespecificeerde, worden toegepast.

Les normes de sécurité exigent que l’appareil soit remis à l’état

d’origine et que soient utiliséés les piéces de rechange identiques

à celles spécifiées.

Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu

beachten. Der Original zustand des Geräts darf nicht verändert werden;

für Reparaturen sind Original-Ersatzteile zu verwenden.

Le norme di sicurezza esigono che l’apparecchio venga rimesso

nelle condizioni originali e che siano utilizzati i pezzi di ricambio

identici a quelli specificati.

"After servicing and before returning set to customer perform a

leakage current measurement test from all exposed metal parts to

earth ground to assure no shock hazard exist. The leakage current

must not exceed 0.5mA."

Repair Hints

3) During repair it is possible to disconnect the Tuner Board

(pos 1103) and CDC & MPEG Module (pos 1105) unless

the fault is suspected to be in that area. This will not affect

the performance of the rest of the set.

4) Due to the short flex cable wires in the ETF Module, the

pc board should be disconnected and reconnected on

the reverse side of the tape mechanism to keep it

electrically connected during repair. See picture 3.

Note: The flex cables are very fragile, care should be taken

not to damage them during repair. After repair, be

very sure that the flex cables are inserted properly

into the flex sockets before encasing, otherwise faults

may occurs.
