To disconnect the set from the mains completely, remove the mains
plug from the wall socket.
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.
All redundant packing material has been omitted. We have done our utmost to make the
packaging easily separable into three mono materials: cardboard (box), polystyrene foam (buffer)
and polyethylene (bags, protective foam sheet).
Environmental information

For MW stations, direct the built-in antenna by turning the whole
set. The telescopic antenna is not needed.
Improving RADIO reception
For FM stations, pull out the telescopic antenna. To improve the
signal, incline and turn the antenna. Reduce its length if the signal
is too strong (very close to a transmitter).
For users in the U.K.: please follow the instructions on page 2.
2 Tune to the desired radio station by using the TUNING wheel.
1 Set the POWER slider to FM or MW to select the desired
wave band.
Radio – tuning to radio stations
The bass level can also be emphasised if you place the set against
wall or shelf. Do not cover any vents; leave sufficient room around
the unit for ventilation.
The battery supply will be switched off when the set is connected
to the mains. To change over to battery supply, pull out the plug
from the unit’s AC MAINS socket.
3 Connect the mains cable to the AC MAINS socket and the wall
socket. This switches on the mains supply. The mains cable is
inside the battery compartment.
2 If the set is equipped with a VOLTAGE selector A, set this
selector to the local mains voltage.
Adjust the volume using the VOLUME control.
1 Check whether the mains voltage as shown on the type plate
corresponds to your local mains voltage. If it does not, consult
your dealer or service organisation. The type plate is located
on the bottom of the set.
Increase and decrease the bass level by pressing DBB.

To record again on this side of the cassette, cover the opening with
a piece of adhesive tape.
Protecting tapes from accidental erasure
Keep the cassette side to be protected in front of you and snap off
the left tab. Now, recording on this side is no longer possible.
At the very beginning and end of the tape, no recording will take
place in the 7 seconds during which the leader tape passes the
recorder heads.
The recording level is set automatically. The controls VOLUME and
DBB do not affect the recording.
For recording on this set you should use a cassette of the type
NORMAL (IEC type I). This deck is not suitable for recording on
cassettes of the type CHROME (IEC type II) or METAL (IEC
type IV).
Recording is permissible insofar as copyright or other rights of
third parties are not infringed upon.

WARNINGS & SAFETY
ESD
© 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.
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
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.
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.

Slide-in error
Generated when the inner-switch did not close within approx. 4s when the pick up is
moved inside. Inner-switch or slide motor problems.
W
Slide-out error
Generated when the inner-switch did not open within approx. 250ms when the pick up is
moved from the inner position outside. Inner-switch or slide motor problems.
W
Jump error.
Triggered when the servo processor counts too less tracks in a defined time during JUMPS.
This can be caused by a disturbed HF-signal (the tracks cannot be recognized exactly),
slide motor problems, track servo problems or scratched discs.
