HANDLING CHIP COMPONENTS

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.

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 Puls-

armband mit Widerstand mit dem Massepotential des

Gerätes verbunden sind.

Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem

Potential.

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.

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

Le norme di sicurezza estigono che l´apparecchio venga

rimesso nelle condizioni originali e che siano utilizzati i

pezzi di ricambiago identici a quelli specificati.

Componenty di sicurezza sono marcati con

Veiligheidsbepalingen vereisen, dat het apparaat in zijn

oorspronkeliijke toestand wordt teruggebracht en dat

onderdelen, identiek aan de gespecificeerde, worden toegepast.

De Veiligheidsonderdelen zijn aangeduid met het symbool

MP3-CD PLAYER

IMPORTANT SPECIFICATIONS

Supported formats:

• Disc format ISO9660, Joliet and multi-session CDs.

Use ISO9660 disc format when burning CD-ROM.

•MP3 music fomats.

• MP3 bit rate (data rate): 32-320 Kbps and variable

bit rate.

• 650Mb and 700Mb CD-R and CD-RWs.

• Directory nesting up to a maximum of 8 levels

(max. 64 characters).

General information

The music compression technology MP3 (MPEG Audio

Layer 3) reduces the original digital audio data by a

factor up to 10 without losing significant sound quali-

ty. This allows you to record up to 10 hours of CD-like

quality music on a single CD-ROM.

How to get MP3 music

Either download legal MP3 music from the internet or

convert your audio CD into MP3 format with any MP3

encoder software, and then record onto a CD-R(W).

•To achieve a good sound quality a bit rate of at

least 128kbps is recommended for MP3 files.

When burning the MP3-CD

• Make sure the file names of the MP3 files end with

.mp3

• Use a writing software capable of recording MP3

track titles (files) in numerical and alphabetical

order. For details on using the software, refer to

the operating instructions of the software.

• Some encoder software offer an option to protect

music files, i.e. the files can only be played on the

computer which created them. If you burn such

files on a CD-ROM, you cannot play them on this

unit. Make sure to deactivate the protection option

in the encoder software before creating the music

files. In this case you are responsible for adherence

to all local or international copyrights.

How to organize MP3 files

You can store up to a maximum number of 35 albums

and 400 titles on one MP3-CD, depending on the song

file sizes.

Albums and titles are alphabetically sorted.

• MP3-CD/ CD albums and titles are shown as num-

bers in the display.

IMPORTANT!

This set does not play/support the following:

• Empty albums: an empty album is an album that

does not contain MP3 files, and will not be shown

in the display.

• Non-supported file formats are skipped. This

means that e.g.: Word documents .doc or MP3

files with extension .dlf are ignored and will not be

played.

•Playlist Files e.g. .m3u, .pls of WMA, AAC,

Winamp, Sonic, RealJukebox, MS Mediaplayer 7.0,

MusicMatch.

• Recordings created on e.g. PacketWriting and

Package Writing.
