HANDLING CHIP COMPONENTS

1 - 1

© 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 décharges statiques (ESD). Leur longévite
pourrait être considérablement écourtée par le fait qu´aucune
précaution nést prise à leur manipulation.
Lors de réparations, s´assurer de bien être relié au même
potentiel que la masse de l´appareil et enfileer 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.

©

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

f

Les normes de sécurité exigent que l`appareil soit remis
à l`état d`origine et que soient utilisées les pièces de
rechange identiques à celles spécifiées.

d WARNUNG

Alle ICs und viele andere Halbleiter sind empfindlich
gegenüber elektrostatischen Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kann die
Lebensdauer drastisch reduzieren.
Sorgen Sie dafür, daß Sie im Reparaturfall über ein Puls­armband mit Widerstand mit dem Massepotential des
Gerätes verbunden sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem
Potential.

d

Bei jeder Reparatur sind die geltenden Sicherheitsvor­schriften zu beachten. Der Originalzustand des Gerätes
darf nicht verändert werden. Für Reparaturen sind Original­ersatzteile zu verwenden.
Sicherheitsbauteile sind durch das Symbol markiert.

SAFETY

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 longevità potrebbe essere fortemente ridatta in caso di
non osservazione della più grande cauzione alla loro
manipolazione. Durante le riparationi occorre quindi essere
collegato allo stesso potenziale che quello della massa
delápparecchio 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.

* Battery compartment – for 6 batteries,

type R-20, UM1 or D-cells

( Voltage selector (inside battery compartment,

some versions only) – adjust to match the local voltage 110/220V before

plugging in the set

) p – 3.5 mm stereo headphone socket

Note: The speakers will be muted when headphones are connected to
the set.

¡ AC MAINS – inlet for mains lead

POWER SUPPLY

Whenever convenient, use the power supply to conserve battery life. Make
sure you remove the power plug from the set and wall outlet before
inserting batteries.

Batteries (not included)

• Insert 6 batteries, type R-20, UM-1 or D-cells, (preferably alkaline)
with the correct polarity.

Remote control (for AZ2045 only)

• Insert 2 batteries, type AAA, R03 or UM4 (preferably alkaline).

Incorrect use of batteries can cause electrolyte leakage and will corrode
the compartment or cause the batteries to burst.

• Do not mix battery types: e.g. alkaline with carbon zinc. Only use
batteries of the same type for the set.

• When inserting new batteries, do not try to mix old batteries with the
new ones.

• Batteries contain chemical substances, so they should be

disposed of properly.

Using AC Power
1 Check if the power supply, as shown on the type plate located on the

bottom of the set, corresponds to your local power supply. If it does

not, consult your dealer or service centre.

2 If your set is equipped with a voltage selector, adjust the selector so

that it matches with the local mains.

3 Connect the mains lead to the wall socket.
4 To disconnect the mains supply, unplug the set from the wall socket.

Auto-Standby mode

When a CD or tape has reached the end of playback and remains in the
stop position for more than
15 minutes, the set will switch off automatically to save power.
