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-
listesagréés,seulshabilitésàréparer
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."

Step 1: Placing speakers
Place the front left and right speakers at equal
distances from the TV set and at an angle of
approximately 45 degrees from the listening
position.
Notes:
–To avoid magnetic interference, do not position
the front speakers too close to your TV set.
– Allow adequate ventilation around the DVD Mini
Hi-Fi System.
Step 2: Connecting speakers

SUBWOOFER OUT
Connect the speaker wires to the SPEAKERS
(FRONT) terminals, right speaker to “R” and left
speaker to “L”, coloured (marked) wire to “+”
and black (unmarked) wire to “–”. 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.
IMPORTANT!
The type plate is located on the rear of
the system.
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.

Step 3: Connecting TV set
IMPORTANT!
–You only need to make one video
connection from the following options,
according to the capabilities of your TV
system.
– S-Video or Component Video
connection provides higher picture
quality.These options must be available
on yourTV set.
–Connect the system directly to the TV
set.
Using Video In jack (CVBS)
Use the composite video cable (yellow) to
connect the system’s CVBS jack to the video
input jack (or labeled as A/V In,Video In,
Composite or Baseband) on the TV set.
To listen to TV channels through this system, use
the audio cables (white/red) to connect AUX/
TV IN (L/R) jacks to the corresponding
AUDIO OUT jacks on the TV set.
Deactivate Progressive Scan through System
Menu. See page 31, Using the Setup Menu –

connect to yourTV set, theVideo signal
will automatically switch to S-Video
when you power up the system. To set
the VIDEO OUT (put) to ‘Pr PbY’, see
page 31, Using the Setup Menu – Setting
the video out.
Using component Video In jack (Pr PbY)
Use the component video cables (red/blue/
green) to connect the system’s Pr PbY jacks to
the corresponding Component video input jacks
(or labeled as Pr/Cr Pb/Cb Y or YUV) on the TV
set.
To listen to TV channels through this system, use
the audio cables (white/red) to connect AUX/
TV IN (L/R) jacks to the corresponding
AUDIO OUT jacks on the TV set.
If you are using a Progressive Scan TV set (TV
must indicate Progressive Scan or ProScan
capability), activate the PROGRESSIVE SCAN
function through SYSTEM MENU.
