HANDLING CHIP COMPONENTS

© 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.

f ATTENTION

Tous les IC et beaucoup d´autres semi-conducteurs sont
sensibles aux décharges statiques (ESD). Leur longévite
pourrait être considérablement écourtée par le fait qu´aucune
précaution nést prise à leur manipulation.
Lors de réparations, s´assurer de bien être relié au même
potentiel que la masse de l´appareil et enfileer 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.

©

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

f

Les normes de sécurité exigent que l`appareil soit remis
à l`état d`origine et que soient utilisées les pièces de
rechange identiques à celles spécifiées.

d WARNUNG

Alle ICs und viele andere Halbleiter sind empfindlich
gegenüber elektrostatischen Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kann die
Lebensdauer drastisch reduzieren.
Sorgen Sie dafür, daß Sie im Reparaturfall über ein Puls­armband mit Widerstand mit dem Massepotential des
Gerätes verbunden sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem
Potential.

d

Bei jeder Reparatur sind die geltenden Sicherheitsvor­schriften zu beachten. Der Originalzustand des Gerätes
darf nicht verändert werden. Für Reparaturen sind Original­ersatzteile zu verwenden.
Sicherheitsbauteile sind durch das Symbol markiert.

SAFETY

ñ 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.

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 riparationi occorre quindi essere
collegato allo stesso potenziale che quello della massa
delápparecchio tramite un braccialetto a resistenza.
Assicurarsi che i componenti e anche gli utensili con quali si
lavora siano anche a questo potenziale.

-- Non-session closed discs

How to organize music files

In order to easily handle the large number of music files on a CD-ROM, you
can organize them in folders (“albums”).

The tracks of an album will be played in alphabetical order. If you want to
arrange them in a certain order, let the file names start with numbers.
For example:

001-ONEWORLD.MP3
002-FIRESTARTER.MP3
003-DEEP.MP3

The albums will be arranged in alphabetical order. If albums are located in an
album, they will be played after this album. Albums without MP3 files will be
skipped.

If there are MP3 files which you did not put into an album, you will find them
in the album number 1.

How to make a CD-ROM with MP3

Use your computer´s CD burner to record (“burn”) the music files from your
hard disk on a CD-ROM. Use either ISO 9660 disc format or UDF. Some CD
burner softwares like e. g. “Draw - to - Disc” or ”InCD” support the UDF for­mat.

Make sure that the file names of the MP3 files end with .mp3.

This set complies with the radio interference requirements of the

European Community.

Environmental information

•

All redundant packing material has been omitted. We have done our utmost to
make the packaging easily separable into three mono materials: EXP220 / 00Z
use clamshell package, EXP221/00C use D box.

•

Your set consists of materials which can be recycled if disassembled by a
specialized company. Please observe the local regulations regarding the disposal
of packing materials, exhausted battery and old equipment.

MP3 music files

The music compression technology MP3 (MPEG Audio Layer 3) reduce the size
of digital data of an audio CD significantly while maintaining CD-like sound
quality. With MP3 you can record up to 10 hours of CD-like music on a single
CD-ROM.

How to get music files

Either download legal music files from the Internet to your computer hard disk
or create them from your own audio CDs. For this, insert an audio CD into
your computer´s CD-ROM drive and convert the music using an appropriate
encoder software select to achieve a good sound quality, a bit rate of 128 kbps
and sampling frequency of 44.1kHZ are recommended for MP3 music files.

Supported formats

This set supports:
– Disc format: ISO 9660, Joliet, Multisession, UDF, Enhanced Music CD,

Mixed Mode CD

– MP3 bit rate: 32–320 kbps and variable bit rate (128 kbps preferable )
– MP3 sampling frequency: 8 - 48 kHz ( 44.1 kHz preferable )
– Total number of music files around 600
– Maximum album number : around 99
