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 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.

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.

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

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.

INSTRUCTION FOR USE
POWER SUPPLY / GENERAL INFORMATION
Use only the AY 3170 adapter (4.5 V / 300 mA direct current, positive pole to the
center pin). Any other product may damage the player.
1 Make sure the local voltage corresponds to the power adapter’s voltage.
2 Connect the power adapter to the 4.5V DC socket of
the player and to the wall socket.
Note: Always disconnect the adapter when you are not
using it.
Environmental information
• All redundant packing material has been omitted. We have done our utmost to
make the packaging easily separable into two materials: cardboard (box) and
polyethylene (bags, protective foam sheet).
• Your set consists of materials which can be recycled if disassembled by a
specialized company. Please observe the local regulations regarding the
disposal of packing materials, exhausted batteries and old equipment.
GENERAL INFORMATION / CD PLAY
Only use the AY 3545 (4822 219 10033) or AY 3548 (3140 118 71890) car voltage
converter (4.5 V DC, positive pole to the centre pin) and the AY 3501 car adapter
cassette. Any other product may damage the set.
1 Put the set on a horizontal, vibration-free and stable surface. Make sure it is
in a safe place, where the set is neither a danger nor an
obstacle to the driver and the passengers.
2 Plug the voltage converter into the

3 If necessary, clean the cigarette lighter socket
to obtain a good electrical contact.
4 Turn down the volume and connect the cassette
adapter plug to LINE OUT/p on the set.
5 Carefully insert the cassette adapter into the car radio’s cassette compartment.
6 Make sure the cord does not hinder your driving.
7 Decease the volume on the set, if necessary. Start playback on the set and
adjust the sound with the car radio controls.
•
Always remove the voltage converter from the cigarette lighter socket
when the set is not in use.
Note: If your car radio has a LINE IN socket , it is better to use it for the
car radio connection instead of the cassette adapter. Connect the signal
