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.
Les composants de sécurité sont marqués

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.

ESD

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

i

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.

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.

Batteries

(not included)

•Insert 6 batteries, type R-20, UM-1 or D-cells,

(preferably alkaline) with the correct polarity.

Remote control

(for AZ2055 only /See A)

• 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 center.

2

If your set is equipped with a voltage selector,
adjust the selector so that it matches with the
local power .

3

Connect the power cord to the wall outlet.

4

To disconnect the power supply, unplug the set
from the wall outlet.

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 energy.

The type plate is located on the bottom of the
set.

BACK PANEL

&Telescopic antenna – improves FM reception
*Battery compartment – for 6 batteries,

type R-20, UM1 or D-cells

(p – 3.5 mm stereo headphone jack

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

)AC MAINS – inlet for power cord

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.
