Motion picture studios want to control the home release of movies in different countries because theater releases arenit
simultaneous (a movie may come out on DVD in the US when itis just hitting screens in Europe). Therefore they have
required that the DVD standard include codes which can be used to lock out the playback of certain discs in certain geographical regions. Players sold in each region will have that regionis code built into the player. The player will refuse to play
these "region coded" discs which are not allowed in the region. However, regional codes are entirely optional. Discs without
codes will play on any player in any country. Some studios have already announced that only their new releases will have
regional codes. There are six regions:
1. United States and Canada2. Europe and Japan
3. Far East (except Japan & China)4. South America and Oceania
5. Africa and the Middle East6. China (except Hong Kong)

Multi-angles:
On some D
VDs, scenes have been filmed from different angles
(up to a maximum of 9). On these discs, you can select the
angle that you want to watch. Please refer to the DVD's manual
to see which scenes have multi-angles.
Resetting the Player to System Settings:
To reset the player, press and hold [STOP] button on the front
panel when pressing Power switch to turn the power on.
All program memory, saved settings from functions such as
Last Memory and Condition Memory are cleard, and all Setup
screen menus are returned to factory settings.
Note:The regional code of the discs must meet to the regional
code of the DV-12S1
The disc format logos shown above are found on disc labels or on disc jackets.
•
To prevent malfunction, do not use an 8 cm (3 in.) adaptor (for CDs).
•
Discs other than the ones indicated above cannot be played on this unit.
•
DVDs that have incompatible region numbers, DVDROM, DVD-RAM, and CD-ROM cannot be
played on this unit. The region number of the player can be found on the rear panel.
* Playing DVD-RW discs (JAPAN & USA model only)
You may not be able to play non-finalized DVD-RW discs.

When playing a DVD-RW disc that was edited on a DVD recorder, you may see scenes from just
before the edited point. This is not a malfunction.
•
Up to 20 characters of a title name can be displayed.
** Playing recordable CDs
Note that this unit cannot record onto recordable discs.

5. WARNING AND LASER SAFETY INSTRUCTIONS
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.

ATTENTION

WARNUNG
I
WAARSCHUWING
AVVERTIMENTO
NL
Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor elektrostatische 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.
Tous les IC et beaucoup d’autres semiconducteurs sont sensibles aux décharges
statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu’aucune précaution
n’est prise a 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 a ce que les composants ainsi que les
outils que l’on utilise soient également a ce
potentiel.
Alle IC und viele andere Halbleiter sind
empfindlich gegen elektrostatische
Entladungen (ESD).
Unsorgfältige Behandlung bei der Reparatur
kann die Lebensdauer drastisch vermindern.
Sorgen sie dafür, das Sie im Reparaturfall
über ein Pulsarmband mit Widerstand mit
dem Massepotential des Gerätes verbunden
sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls
auf diesem Potential.
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 in zijn oorspronkelijke
toestand wordt terug gebracht en dat onderdelen, identiek aan de
gespecifieerde worden toegepast.
F
Les normes de sécurité exigent que l’appareil soit remis a l’état d’origine et
que soient utilisées les pièces de rechange identiques à celles spécifiées.
Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche (ESD).
La loro longevita potrebbe essere fortemente
ridatta in caso di non osservazione della piu
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.
D
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten.
Der Originalzustand des Gerats darf nicht verandert werden.
Fur Reparaturen sind Original-Ersatzteile zu verwenden.
I
Le norme di sicurezza esigono che l’apparecchio venga rimesso nelle
condizioni originali e che siano utilizzati pezzi di ricambiago idetici a quelli
specificati.
SHOCK, FIRE HAZARD SERVICE TEST:
CAUTION: After servicing this appliance and prior to returning to customer, measure the resistance between
either primary AC cord connector pins (with unit NOT connected to AC mains and its Power switch ON), and the
face or Front Panel of product and controls and chassis bottom,
Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC
power is applied, and verified before return to user/customer.
Ref.UL Standard NO.1492.
NOTE ON SAFETY:
Symbol
: Fire or electrical shock hazard. Only original parts should be used to replace any part with symbol
Any other component substitution(other than original type), may increase risk or fire or electrical shock hazard.

LASER SAFETY
This unit employs a laser. Only a qualified service person should remove the cover or attempt to service this
device, due to possible eye injury.
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURE OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
AVOID DIRECT EXPOSURE T O BEAM
WARNING
The use of optical instruments with this product will increase eye hazard.
Repair handling should take place as much as possible with a disc loaded inside the player
