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.

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 mme
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.

WARNUNG

Alle ICs und viele andere Halbleiter sind empfindlich
gegen ber elektrostatischen Entladungen (ESD).
Unsorgf ltige Behandlung im Reparaturfall kann die
Lebensdauer drastisch reduzieren.
Sorgen Sie daf r, da⁄ Sie im Reparaturfall ber ein Puls­armband mit Widerstand mit dem Massepotential des
Ger tes verbunden sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem
Potential.

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.

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.

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

Le norme di sicurezza estigono che l˙apparecchio venga
rimesso nelle condizioni originali e che siano utilizzati i
pezzi di ricambiago identici a quelli specificati.
Componenty di sicurezza sono marcati con

Veiligheidsbepalingen vereisen, dat het apparaat in zijn
oorspronkeliijke toestand wordt teruggebracht en dat
onderdelen, identiek aan de gespecificeerde, worden toegepast.

LASER PRODUCT

DANGER: Invisible laser radiation when open.

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.

AVOID DIRECT EXPOSURE TO BEAM.

SERVICE PLAY TEST

Set is in Service PLAY Mode.

The Service Play Mode is intended to
detect and identify the failures in the CD Mode.

In this mode the electronics will still function
even when an error is detected so that
repair activities can be carried out.

In case of failures, error

codes according to table 1

will be displayed.
