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
• Replace the battery or connect the mains adapter as
soon as blinks and Replace batteries is
scrolled.
Remove batteries if they are empty or if the unit will
not be used for a long time.
Batteries contain chemical substances, so they
should be disposed of properly.

In-car connections (supplied or optionally available)
Only use the AY 3545or AY 3548 car voltage converter (4.5 V DC, positive pole
to the centre pin) and the AY 3501 car cassette adapter. Any other product
may damage the set.
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.
4 Tu rn down the volume and connect the adapter cassette plug to LINE OUT/p
on the set.
5 Carefully insert the adapter cassette into the car radio’s cassette compartment.
6 Make sure the cord does not hinder your driving.
7 Start playback on the set and adjust the sound with the car radio controls.
• Always remove the voltage converter from the cigarette lighter socket
when
the set is not in use.
Note: If your car radio has a LINE IN socket, it is better to connect the set to this
jack
instead of using the cassette adapter. Connect LINE OUT /
p of
the
set with the LINE IN jack of your car radio with an appropriate cable.

SAFETY & WARNINGS
© 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.
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.

i AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono sensibili alle scariche
