HANDLING CHIP COMPONENTS
WARNING
©
All ICs and many other semiconductors 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 wristband with
resistance. Keep components and tools at this potential.
f
ATTENTION
Tous les IC et beaucoup d«autres semi-conducteurs sont
sensibles aux d charges statiques (ESD). Leur long vite
pourrait tre consid rablement court e par le fait qu«aucune
pr caution n st prise leur manipulation.
Lors de r parations, s«assurer de bien tre reli au m me
potentiel que la masse de l«appareil et enfileer le bracelet
serti d«une r sistance de s curit .
Veiller ce que les composants ainsi que les outils que l«on
utilise soient galement 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.
Safety components are marked by the symbol

Unsorgf ltige Behandlung im Reparaturfall kann die

Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem

ñ
WAARSCHUWING
Alle IC«s en vele andere halfgeleiders zijn gevoelig voor
electrostatische ontladingen (ESD).
Onzorgvuldig behandelen tijdens reparatie kan de levensduur
drastisch doen vermindern. 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.
i
AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono sensibili alle scariche
statiche (ESD).
La loro longevit potrebbe essere fortemente ridatta in caso di
non osservazione della pi grande cauzione alla loro
manipolazione. Durante le riparationi occorre quindi essere
collegato allo stesso potenziale che quello della massa
del pparecchio tramite un braccialetto a resistenza.
Assicurarsi che i componenti e anche gli utensili con quali si
lavora siano anche a questo potenziale.
ñ
Veiligheidsbepalingen vereisen, dat het apparaat in zijn
oorspronkeliijke toestand wordt teruggebracht en dat
onderdelen, identiek aan de gespecificeerde, worden toegepast.
De Veiligheidsonderdelen zijn aangeduid met het symbool

Le norme di sicurezza estigono che l«apparecchio venga
rimesso nelle condizioni originali e che siano utilizzati i

After servicing and before returning the set to customer
perform a leakage current measurement test from all
exposed metal parts to earth ground, to assure no
shock hazard exists.
The leakage current must not exceed 0.5mA.

If sensitivity of frequency counter is too low adjust to max. channel separation
(input signal: stereo left 90% + 9%, adjust output on right channel to minimum)
2)
RC network serves for damping the IF-filter while adjusting the other one.
3)
For AM RF adjustments the original frame antenna has to be used!
