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.

Veiligheidsbepalingen vereisen, dat het apparaat in zijn

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.

Erasing a programme
You can erase the contents of the memory by:
– opening the CD door;
– selecting TUNER source;
– pressing 9 (twice during playback or in the stop
position).
Display: shows briefly when
programme is cancelled. (See @)
Precautions & General Maintenance (See #)
• Place the set on a hard and flat surface so that the
system does not tilt.
• Do not expose the set, batteries or CDs to
humidity, rain, sand or excessive heat caused by
heating equipment or direct sunlight.
• Do not cover the set. Adequate ventilation with a
minimum gap of 6 inches between the ventilation
holes and surrounding surfaces is necessary to
prevent heat build-up.
• The mechanical parts of the set contain self-
lubricating bearings and must not be oiled or
lubricated.
•To clean the set, use a soft dry cloth. Do not use
any cleaning agents containing alcohol, ammonia,
benzene or abrasives as these may harm the
housing.
CD player and CD handling (See $)
• The lens of the CD player should never be touched!
• Sudden changes in the surrounding temperature
can cause condensation to form and the lens of
your CD player to cloud over. Playing a CD is then
not possible. Do not attempt to clean the lens but
leave the set in a warm environment until the
moisture evaporates.
• Always close the CD door to keep the CD
compartment dust-free. To clean, dust the
compartment with a soft dry cloth.
•To clean the CD, wipe in a straight line from the
centre towards the edge using a soft, lint-free
cloth. Do not use cleaning agents as they may
damage the disc.
• Never write on a CD or attach any stickers to it.

Troubleshooting
If a fault occurs, first check the points listed below before taking the set for repair.
Do not open the set as there is a risk of electric shock.
If you are unable to remedy a problem by following these hints, consult your dealer or service centre.
WARNING: Under no circumstances should you try to repair the set yourself, as this will invalidate the
guarantee.
