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."

Rating - NO PARENTAL
Preparations
Parental control is not activated, it will play all discs.
Rating - 1 to 9
If the player’s parental level is set below 9, only discs with a
lower or equal level will play. For example, if the player is
set to 5, only discs with ratings of 5, 4, 3, 2 and 1 will be
played. Higher rated scenes will not be played unless an
alternative which has the same rating or lower is available
on the disc. For example, consider a disc that generally is
suitable for most audiences, and it is rated at level 2 for the
most part. However, in the middle, there are also scenes
rated at 5 (not suitable for children).
NO PARENTAL – It will play all discs.

Care and safety information
Avoid high temperatures, moisture, water and
dust.
–Do not expose the system, batteries or discs to
humidity, rain, sand or excessive heat (caused by heating
equipment or direct sunlight.) Always keep the disc tray
closed to avoid dust on the lens.
Avoid condensation problem
– The lens may cloud over when the player is suddenly
moved from cold to warm surroundings, making it
impossible to play a disc. Leave the player in the warm
environment until the moisture evaporates.
Do not block the vents
–Do not operate the DVD system in an enclosed
cabinet, allow about 10 cm (4 inches) of free space all
around the player for adequate ventilation.
Care of disc
–To clean a CD, wipe it in a straight line
from the center towards the edge using a soft,
lint-free cloth. A cleaning agent may damage
the disc.
–Write only on the printed side of a
CDR(W) and only with a soft felt-tipped pen.
– Handle the disc by its edge, do not touch the surface.
Care of cabinet
–Use a soft cloth slightly moistened with a mild detergent
solution. Do not use a solution containing alcohol, spirits,
ammonia or abrasives.
Finding a suitable location
–Place the player on a flat, hard, and stable surface.
Step 1: Placing the speakers
and subwoofers
For best possible surround sound, all the speakers (exept
subwoofer) should be placed at the same distance from the
listening position.
1Place the front left and right speakers at equal distances
from the TV and at an angle of approximately 45 degrees
from the listening position.
2Place the centre speaker above the TV or the DVD system
so the centre channel’s sound is localized.
3Place the surround speakers at normal listening ear level
facing each other.
4Place the subwoofer on the floor near theTV.
Notes:
–To avoid magnetic interference, do not position the front
speakers too close to your TV.
– Allow adequate ventilation around the DVD system.
