GENERAL INFORMATION

Maintenance

• Do not touch the lens A of the set. Do not expose the set, battery or discs to humidity, rain, sand or excessive

• heat (caused by heating equipment or direct sunlight).

• The lens may cloud over when the set is suddenly moved from cold to warm surroundings. Playing is not possible then. Leave the set in a warm environment until the moisture evaporates.

• Active mobile phones in the vicinity of this set may cause malfunctions. Avoid dropping the set as this may cause damage.

•

• Clean the set with a soft, lint-free cloth. Do not use any cleaning agents as they may have a corrosive effect.

• To clean a disc, wipe it in a straight line fr using a soft, lint-free cloth. Cleaning agents may damage the disc.

Environmental information

•

All redundant packing material has been omitted. We have done our utmost to make the packaging easily separable into three mono materials: cardboard (box), polystyrene foam (buffer) and polyethylene (bags, protective foam sheet).

•

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 batter

INSTRUCTIONS FOR USE

GENERAL INFORMATION

MP3 music files

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

How to get music files

Either download legal music files from the Internet to your computer disk or buy pre-recorded music CD. 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.

Some encoder software offers 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 set. 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 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

GENERAL INFORMATION

This set will play all albums in alphabetical order. An album name includes all folders in which the album is located, e. g. the album VERDI in CLASSIC has the album name CLASSIC\VERDI. The albums in the illustration will be played in the following way:

ALBU M

CLASSIC 1 CLASSIC\MOZART 2 CLASSIC\VERDI 3 POP\BLUR 4 REGGAE 5

In POP there are no MP3 files. POP is therefore skipped.

There may be an album 0 which will be played before all other albums. Album 0 contains all tracks which you did not put into an album.

How to make a CD-ROM with MP3

Record (“burn”) the music files from your hard disc on a CD-ROM with your computer´s CD burner.

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

When burning your MP3-CDs, use either ISO 9660 disc format or UDF. CD burning software like “DirectCD” or others support the UDF format.

GENERAL INFORMATION

Supported formats

This set supports:

–

Disc format: ISO 9660, Joliet, Multisession, UDF, Enhanced Music CD, Mixed Mode CD

–

Music file format: MP3

MP3 bit rate (data rate): 32–320 kbps and variable bit rate

–

Total number of music files and albums: around 350 (with a typical file name length of 20 characters)

Note: The number of music files that can be played depends on the length of the file names. With short file names more files will be supported.

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.

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.

SAFETY

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.

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.

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.

s Varning !

Osynlig laserstrålning när apparaten är öppnad och spärren är urkopplad. Betrakta ej strålen.

After servicing and before returning the set to customer perform a leakage current measurement test from all exposed metal parts to earth ground, to assure no shock hazard exists. The leakage current must not exceed 0.5mA.
