HANDLING CHIP COMPONENTS

GB
WARNING
All ICs and many other semi-conductors 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 wrist wrap with resistance.
Keep components and tools also at this
potential.
F
ATTENTION
Tous les IC et beaucoup d’autres
semi-conducteurs sont sensibles aux
décharges statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu’aucune précaution n’est
prise à leur manipulation.
Lors de réparations, s’assurer de bien être relié
au même potentiel que la masse de l’appareil et
enfiler 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.
ESD
D
WARNUNG
Alle ICs und viele andere Halbleiter sind
empfindlich gegenüber elektrostatischen
Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kan
die Lebensdauer drastisch reduzieren.
Veranlassen Sie, dass Sie im Reparaturfall über
ein Pulsarmband mit Widerstand verbunden
sind mit dem gleichen Potential wie die Masse
des Gerätes.
Bauteile und Hilfsmittel auch auf dieses gleiche
Potential halten.
NL
WAARSCHUWING
Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor electrostatische ontladingen
(ESD).
Onzorgvuldig behandelen tijdens reparatie kan
de levensduur drastisch doen verminderen.
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 riparazioni occorre quindi essere
collegato allo stesso potenziale che quello della
massa dell’apparecchio tramite un braccialetto
a resistenza.
Assicurarsi che i componenti e anche gli utensili
con quali si lavora siano anche a questo
potenziale.
“Pour votre sécurité, ces documents
doivent être utilisés par des spécia-
listes agréés, seuls habilités à réparer
votre appareil en panne”.
GB
Safety regulations require that the set be restored to its original
condition and that parts which are identical with those specified,
be used.
NL
Veiligheidsbepalingen vereisen, dat het apparaat bij reparatie in
zijn oorspronkelijke toestand wordt teruggebracht en dat onderdelen,
identiek aan de gespecificeerde, worden toegepast.
F
Les normes de sécurité exigent que l’appareil soit remis à l’état
d’origine et que soient utiliséés les piéces de rechange identiques
à celles spécifiées.
D
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu
beachten. Der Original zustand des Geräts darf nicht verändert werden;
für Reparaturen sind Original-Ersatzteile zu verwenden.
I
Le norme di sicurezza esigono che l’apparecchio venga rimesso
nelle condizioni originali e che siano utilizzati i pezzi di ricambio
identici a quelli specificati.
"After servicing and before returning set to customer perform a
leakage current measurement test from all exposed metal parts to
earth ground to assure no shock hazard exist. The leakage current
must not exceed 0.5mA."

Preparations
Rear Connections
The type plate is located at the rear of the
system.
A
Power
Before connecting the AC power cord to the
wall outlet, ensure that the following are done;
-If your system is equipped with a
Voltage Selector, set the VOLTAGE
SELECTOR to the local power line
voltage.
- All other connections have been made.
WARNING!
-For optimal performance, use only the
original power cable.
-Never ma keor change any connections
with the power switched on.
To avoid overheating of the system, a safety
circuit has been built in. Therefore,your
system may switch to Standby mode
automatically under extreme 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 terminals. 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.
FM Antenna
For better FM stereo reception, connect an
outdoor FM antenna to the FM ANTENNA
terminal.

Fully insert the stripped portion of the speaker
wire into the terminal 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 speakers supplied. Please refer to
the SPECIFICATIONS section of this manual.
D
Video Out Connection
Connect the VIDEO OUT (CVBS) terminal
at the rear of the system to the TV or VCR
VIDEO IN for viewing or recording.
Note:
–To avoid magnetic interference with the picture
on your TV, do not position the front speakers too
close to the TV.
E
Connecting other equipment to your
system
Connect the audio left and right OUT terminals
of a TV, VCR, Laser Disc player, DVD player or
CD Recorder to the AUX/CDR IN terminals.
Note:
–If you ar e connecting equipment with a mono
output (a single audio out terminal), connect it to
the AUX/CDR IN left terminal. Alternatively, you
can use a "single to double" cinch cable (still be
mono sound).
Inserting batteries into the
Remote Control
Insert two batteries (Type R06 or AA) into the
remote control with the correct polarity as
indicated by the +and -symbols inside the
battery compartment.
CAUTION!
– Remove batteries if they are exhausted
or not to be used for a long time..
– Do not use old and new or different
types of batteries in combination.
– Batteries contain chemical substances, s o
they should be disposed off properly.

Repair Hints
3) During repair it is possible to disconnect the Tuner Board
(pos 1103) and CDC & MPEG Module (pos 1105) unless
the fault is suspected to be in that area. This will not affect
the performance of the rest of the set.
4) Due to the short flex cable wires in the ETF Module, the
pc board should be disconnected and reconnected on
the reverse side of the tape mechanism to keep it
electrically connected during repair. See picture 3.
Note: The flex cables are very fragile, care should be taken
not to damage them during repair. After repair, be
very sure that the flex cables are inserted properly
into the flex sockets before encasing, otherwise faults
may occurs.
