HANDLING CHIP COMPONENTS

1 - 1

© 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.

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.

©

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

f

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.

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.

d

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

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.

Veiligheidsbepalingen vereisen, dat het apparaat in zijn
oorspronkeliijke toestand wordt teruggebracht en dat
onderdelen, identiek aan de gespecificeerde, worden toegepast.

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.

POWER SUPPLY

Whenever convenient, use the AC power supply to

conserve battery life. Make sure you remove the

power plug from the set and wall outlet before

inserting batteries.

Batteries (not included)

• Insert 6 batteries, type R-14, UM-2 or C-cells,
(preferably alkaline) with the correct polarity. (See 6)

• Remote control (AZ1305 model only)
Insert 2 batteries, type AAA, R03 or UM4
(preferably alkaline). (See 8)

IMPORTANT!

• 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 centre.

2.

Connect the mains lead to the wall socket.

3.

To disconnect the mains supply, unplug the set

from the wall socket.

This set complies with the radio interference
requirements of the European Community.

For users in the U.K., please follow the boxed
instructions ‘Important notes...’ on this sheet.

SAFETY & MAINTENANCE INFORMATION
(See 7)

• Don't expose the set, batteries, CDs to humidity,

rain, sand or excessive heat.

• Clean the set with a dry cloth. Don't use any

cleaning agents containing alcohol, ammonia,

benzene or abrasives as these may harm the set.

•Place the set on a hard and flat surface so that the

system does not tilt. Make sure there is good

ventilation to prevent the set overheating.

•The mechanical parts of the set contain

self-lubricating bearings and must not be oiled or

lubricated.

CD player and CD handling

• If the CD player cannot read CDs correctly, use a

cleaning CD to clean the lens before taking the set

to repair.

•The lens of the CD player should never be touched!

• Sudden changes in the surrounding temperature

can cause condensation on the lens of your CD

player. Playing a CD is then not possible. Do not

attempt to clean the lens but leave the set in a

warm environment until the moisture evaporates.

• Always close the CD door to avoid dust on the lens.

•To clean the CD, wipe in a straight line from the

centre towards the edge using a soft, lint-free

cloth. Do not use cleaning agents as they may

damage the disc.

•

Never

write on a CD or attach any stickers to it.

DIGITAL TUNER
Tuning to radio stations

1.

Adjust the POWER slider to MW or FM.

™ The radio. station frequency, waveband are

shown (See 3)

2.

Press and hold SEARCH

or §

until the

frequency in the display starts running.

™ The radio automatically tunes to a station of

sufficient reception. Display shows Srch

during automatic tuning.

Environmental information

We have done our best to reduce the packaging and make it easy to separate into 3 materials:
cardboard, expandable polystyrene, polyethylene.

Your set consists of materials which can be recycled if disassembled by a
specialized company. Please observe the local regulations regarding the
disposal of packaging, exhausted batteries and old equipment.

If a fault occurs, first check the points listed below before taking the set for repair.
If you are unable to remedy a problem by following these hints, consult your dealer or service centre.

WARNING:

Do not open the set as there is a risk of electric shock! Under no
circumstances should you try to repair the set yourself, as this will
invalidate the guarantee.
