HANDLING CHIP COMPONENTS

WARNING

ESD

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 Pulsarmband mit Widerstand mit dem Massepotential des
Gerätes verbunden sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem
Potential.

SAFETY

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.

ñ

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

Veiligheidsbepalingen vereisen, dat het apparaat in zijn

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.

About MP3
The music compression technology MP3 (MPEG Audio
Layer 3) reduces the digital data of an audio CD
significantly while maintaining CD-like sound quality.
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 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.

Helpful Hints:
– For details on using MP3 encoder and writing software, please refer to the operating instructions of
the software.
– Make sure that the file names of the MP3 files end
with .mp3.
– Total number of music files and albums: around 350
(with a typical file name length of 20 characters)
– 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.

7 ALBUM/PRESET
+,
MP3-CD only : – selects previous/ next albums.
Tuner : – selects previous/next preset station.
POWER SUPPLY
Whenever convenient, use the power supply to
conserve battery life. Make sure you remove the
power cord from the set and wall jack before inserting
batteries.

Remote control (See B)
• Insert 2 batteries, type AAA, R03 or UM4
(preferably alkaline).

Helpful Hints:
• Incorrect use of batteries can cause electrolyte
leakage and will corrode the compartment or cause
the batteries to burst.
• Do not mix battery types: e.g. alkaline with carbon
zinc. Only use batteries of the same type for the
set.
• When inserting new batteries, do not try to mix old
batteries with the new ones.
• Batteries contain chemical substances, so
they should be disposed of properly.
USING AC POWER

1. Check if the AC power supply, as shown on the
type plate located on the bottom of the set,
corresponds to your local power supply. If it does
not, consult your dealer or service center.
2. If your set is equipped with a voltage selector,
adjust the selector so that it matches with the
local power supply.
3. Connect the mains lead to the wall jack and the
set is now ready for use.
Helpful Hints:
– To disconnect the power supply, unplug the set
from the wall jack.
– Disconnect the power supply to protect your set
during heavy thunderstorms.
POWER-SAVING AUTOMATIC STANDBY
As a power-saving feature, the system automatically
switches to standby 15 minutes after MP3-CD/CD has
reached the end and no control is operated.

The type plate is located on the bottom of
the set.

BATTERIES
