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.

•A

void dropping the set as this may cause damage.

•C

lean 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 from the centre towards the edge using a soft, lint-free cloth. Cleaning agents may damage the disc.

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 Various with album number 0. Various is the ﬁrst album that will be played.

How to make a CD-ROM with MP3

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.

GENERAL INFORMATION

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 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. To achieve a good sound quality, a bit rate of 128 kbps or higher is recommended for MP3 music ﬁles.

This set complies with the radio interference requirements of the

European Community.

POWER SUPPLY / BASIC FUNCTIONS

Mains adapter (supplied or optionally available)

Only use the AY 3170 mains adapter (4.5 V/300 mA direct current, positive pole to the center pin). Any other product may damage the set.

1 Make sure the local voltage corresponds to the

adapter´s voltage. If your mains adapter is equipped with a voltage selector, set this selector to the local mains voltage if necessary.

2 Connect the mains adapter to 4.5V DC on the set and to the wall outlet.

Note: Always disconnect the adapter if you are not using it.

Headphones (SBC HE205 or HL351)

• Connect the supplied headphones to LINE OUT/ p.

Note: LINE OUT/p can also be used for connecting this set to your HiFi system. Adjust the volume and sound on both the CD player and your HiFi system.

IMPORTANT!

• Hearing safety :

Do not play your headphones at a high volume. Hearing experts advise that continuous use at high volume can permanently damage your hearing.

• Trafﬁc safety :

Do not use headphones while driving a vehicle. It may create a hazard and it is illegal in many countries. Even if your headphones are an open-air type designed to let you hear outside sounds, do not turn up the volume so high that you cannot hear what is going on around you.

Batteries (supplied or optionally available)

Inserting batteries

•Open the battery compartment and insert either

2normal or alkaline batteries type AA (LR6, UM3).

Old and new or different types of batteries should not be combined.

Indication of empty batteries

1 Put the set on a horizontal, vibration-free and

stable surface. Make sure it is in a safe place, where the set is neither a danger nor an obstacle to the driver and the passengers.

2 Plug the voltage converter into the

cigarette lighter socket (only for 12 V car battery, negative grounding), then connect the wired end with 4.5V DC input socket on the set.

3 If necessary, clean the cigarette lighter socket to obtain a good electrical

contact.

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 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

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. Les composants de sécurité sont marqués

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

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

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.
