WARNING

All ICs and many other semi-conductors 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 wrist wrap with resistance. Keep components and tools also at this potential.

ATTENTION

Tous les IC et beaucoup d’autres semi-conducteurs sont sensibles aux décharges statiques (ESD). Leur longévité pourrait être considérablement écourtée par le fait qu’aucune précaution n’est prise à leur manipulation. Lors de réparations, s’assurer de bien être relié au même potentiel que la masse de l’appareil et enfiler 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.

ESD

WARNUNG

Alle ICs und viele andere Halbleiter sind empfindlich gegenüber elektrostatischen Entladungen (ESD). Unsorgfältige Behandlung im Reparaturfall kan die Lebensdauer drastisch reduzieren. Veranlassen Sie, dass Sie im Reparaturfall über ein Pulsarmband mit Widerstand verbunden sind mit dem gleichen Potential wie die Masse des Gerätes. Bauteile und Hilfsmittel auch auf dieses gleiche Potential halten.

WAARSCHUWING

Alle IC’s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen verminderen. 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.

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 riparazioni occorre quindi essere collegato allo stesso potenziale che quello della massa dell’apparecchio tramite un braccialetto a resistenza. Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale.

Safety regulations require that the set be restored to its original condition and that parts which are identical with those specified, be used.

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

Les normes de sécurité exigent que l’appareil soit remis à l’état d’origine et que soient utiliséés les piéces de rechange identiques à celles spécifiées.

Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten. Der Original zustand des Geräts darf nicht verändert werden; für Reparaturen sind Original-Ersatzteile zu verwenden.

“Pour votre sécurité, ces documents doivent être utilisés par des spécialistes agréés, seuls habilités à réparer votre appareil en panne”.

PREP ARATIONS AND CONTROLS

Preparations

Rear connections

The type plate is located at the rear of the

system.

Po w e r

Before connecting the AC power cord to the

wall outlet, ensure that all other connections

have been made .

WARNING!

–For optimal performance, use only the

original power cable .

–Never make or change any connections

with the power switched on.

Antennas Connection

Connect the supplied AM loop antenna and FM

antenna to the respective terminals. Adjust the

position of the antenna for optimal reception.

AM Antenna

Fix the claw

to the slot

● Position the antenna as far as possible from a TV,

VCR or other radiation source

Preparations

FM Antenna

● For better FM stereo reception, connect an

outdoor FM antenna to the FM ANTENNA

terminal.

Speakers Connection

Front Speakers

Connect the speaker wires to the SPEAKERS

terminals, right speaker to "R" and left speaker to

"L", coloured (marked) wire to "+" and black

(unmarked) wire to "-".

● Fully insert the stripped por tion of the speaker

wire into the terminal as shown.

Notes:

–For optimal sound performance, use the

supplied speakers.

–Do not connect more than one speaker to any

one pair of +/- speaker terminals.

–Do not connect speakers with impedance lower

than the speakers supplied. Please refer to the

SPECIFICATIONS section of this manual.

Inserting batteries into the

remote control

Insert two batteries type R03 or AAA (not

supplied) into the remote control with the

correct polarity as indicated by the "+" and

"-" symbols inside the battery compartment.

CAUTION!

– Remove batteries if they are exhausted

or will not be used for a long time.

–Do not use old and new or different

types of batteries in combination.

– Batteries contain chemical substances, so

they should be disposed off properly

Important notes for users in the

U.K.

Mains plug

This apparatus is fitted with an approved 13

Amp plug. To change a fuse in this type of plug

proceed as follows:

Remove fuse cover and fuse.

Fix new fuse which should be a BS1362 5 Amp,

A.S.T.A. or BSI approved type.

Refit the fuse cover.

If the fitted plug is not suitable for your socket

outlets, it should be cut off and an appropriate

plug fitted in its place.

If the mains plug contains a fuse, this should

have a value of 5 Amp. If a plug without a fuse

is used, the fuse at the distribution board

should not be greater than 5 Amp.

Note: These vered plug must be disposed of to

avoid a possible shock hazard should it be

inserted into a 13 Amp socket else where.

How to connect a plug

The wires in the mains lead are coloured with

the following code: blue = neutral (N),

brown = live (L).

¶ As these colours ma y not cor respond with the

colour mar kings identifying the terminals in

your plug, proceed as follows:

– Connect the blue wire to the terminal

marked N or coloured black.

– Connect the brown wire to the terminal

marked L or coloured red.

– Do not connect either wire to the earth

terminal in the plug, marked E (or e) or

coloured green (or green and yellow).

Before replacing the plug cover, make certain

that the cord grip is clamped over the sheath

of the lead - not simply over the two wires.
