MP3 MUSIC FILES

The music compression technology MP3 (MPEG Audio Layer 3) reduces the 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 disc 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. To achieve a good sound quality, a bit rate of 128 kbps or higher is recommended for MP3 music ﬁles.

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 01.

Various

is the ﬁrst album that will be

played.

How to make a CD-ROM with MP3 ﬁles

Use your computer´s CD burner to record (“burn”) the music ﬁles from your hard disc on a CD-ROM. Use either ISO 9660 disc format or UDF. Some CD burner software like e.g. “DirectCD” support the UDF format. Make sure that the ﬁle names of the MP3 ﬁles end with .mp3.

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 –Total number of music ﬁles and albums: around 350 (with a typical

ﬁle name length of 64 characters)

Notes: – All trademarks used are owned by their respective owners.

CD PLAYER AND CD HANDLING

• Do not touch the lens A of the CD player.

• Do not expose the unit, batteries or CDs to humidity, rain, sand or excessive heat (caused by heating equipment or direct sunlight).

•You can clean the CD player with a soft, slightly dampened, lint-free cloth. Do not use any cleaning agents as they may have a corrosive effect.

SAFETY & WARNINGS

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.

ESD

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.

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.

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.

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

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

DANGER: Invisible laser radiation when open. AVOID DIRECT EXPOSURE TO BEAM.
