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.
ATTENTION
Tous les IC et beaucoup d˙autres semi-conducteurs sont
sensibles aux d charges statiques (ESD). Leur long vite
pourrait tre consid rablement court e par le fait qu˙aucune
pr caution n st prise leur manipulation.
Lors de r parations, s˙assurer de bien tre reli au m me
potentiel que la masse de l˙appareil et enfileer le bracelet

Veiller ce que les composants ainsi que les outils que l˙on
utilise soient galement ce potentiel.

WARNUNG
Alle ICs und viele andere Halbleiter sind empfindlich
gegen ber elektrostatischen Entladungen (ESD).
Unsorgf ltige Behandlung im Reparaturfall kann die
Lebensdauer drastisch reduzieren.
Sorgen Sie daf r, da⁄ Sie im Reparaturfall ber ein Pulsarmband mit Widerstand mit dem Massepotential des
Ger tes verbunden sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem
Potential.

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.
AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono sensibili alle scariche
statiche (ESD).
La loro longevit potrebbe essere fortemente ridatta in caso di
non osservazione della pi grande cauzione alla loro
manipolazione. Durante le riparationi occorre quindi essere
collegato allo stesso potenziale che quello della massa
del pparecchio tramite un braccialetto a resistenza.
Assicurarsi che i componenti e anche gli utensili con quali si
lavora siano anche a questo potenziale.
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
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.
Componenty di sicurezza sono marcati con
Veiligheidsbepalingen vereisen, dat het apparaat in zijn
oorspronkeliijke toestand wordt teruggebracht en dat
onderdelen, identiek aan de gespecificeerde, worden toegepast.

DANGER: Invisible laser radiation when open.
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.
AVOID DIRECT EXPOSURE TO BEAM.

Preparations
FM Antenna
For better FM stereo reception, connect an
outdoor FM antenna to the FM
AERIAL (FM
ANTENNA) ter minal.
Speakers Connection
Front Speakers
Connect the speaker wires to the SPEAKERS
terminals, right speaker to "
RIGHT
" and left
speaker to "LEFT", coloured (mar ked) wire to
"+" and black (unmar ked) wire to "
-
".

2
Fully inser t the str ipped por tion of the speaker
wire into the ter minal as shown.
Notes:
–For optimal sound performance, use the
supplied speakers .
– Do not connect more than one speaker to any
one pair of
+
/
-
speaker terminals .
– Do not connect speakers with an impedance
lower than the speak
ers supplied. Please refer to
the SPECIFICATIONS section of this manual.
Optional connection
The optional equipment and connecting cords
are not supplied. Ref
er to the operating
instructions of the connected equipment for
details.
Connecting other equipment to your
system
Connect the audio left and right OUT terminals
of a TV, VCR, Laser Disc player, DVD pla yer or
CD Recorder to the AUX IN terminals.
Note:
– If you are connecting equipment with a mono
output (a single audio out terminal), connect it to
the AUX IN left terminal. Alternatively, you can use
a “single to double” cinch cable (the output sound
still remain mono).
Inserting batteries into the
remote control
Insert two batteries (not supplied) type R03 or
AAA into the remote control with the correct
polarity as indicated by the "
+
" and "-"
symbols inside the battery compar tment.
CAUTION!
– Remove batteries if they are exhausted
or will not be used for a long time.
– Do not use old and new or different
types of batteries in combination.
– Batteries contain chemical substances, so
they should be disposed off properly.

Before connecting the AC power cord to the
wall outlet, ensure that all other connections
have been made
.
WARNING!
–For optimal performance
,
use only the
original power cable .
–Never make or change any connections
with the power switched on.
To avoid overheating of the system, a safety
circuit has been built in. Ther efore, your
system may switch to Standb
y mode
automatically under e
xtreme conditions. If
this happens, let the system cool down
before reusing it (not available for all versions) .
B Antennas Connection
Connect the supplied AM loop antenna and FM
antenna to the respective ter minals. Adjust the
position of the antenna for optimal reception.
AM Antenna
Position the antenna as far as possible from a TV,
VCR or other radiation source .
