© 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.
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.
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.

Brief Operating Instruction
Preparations
FM Antenna
For better FM stereo reception, connect an
outdoor FM antenna to the FM ANTENNA
terminal.
C Speakers Connection
Front Speakers
Connect the speaker wires to the SPEAKERS
(FRONT) terminals, right speaker to "R" and left
speaker to "L", coloured (marked) wire to "+"
and black (unmarked) wire to "-".
1
2
Fully insert the stripped portion 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 an impedance
lower than the speakers supplied. Please refer to
the SPECIFICATIONS section of this manual.
Optional connections
The optional equipment and connecting cords
are not supplied. Refer to the operating
instructions of the connected equipment for
details.
Subwoofer Out connection
Connect the subwoofer to the SUBWOOFER
OUT terminal. The subwoofer reproduces just
the low bass sound effect (explosions or the
rumble of spaceships, for example).
Connecting other equipment to your
system
Connect the audio left and right OUT terminals
of a TV, VCR, Laser Disc player, DVD player or
CD Recorder to the AUX/CDR IN terminals.
Note:
– If you are connecting equipment with a
monaural output (a single audio out terminal),
connect it to the AUX/CDR IN left terminal.
Alternatively, you can use a “single to double” cinch
cable (still be monaural sound).
Digital Out connection
Connect this digital output when recording on
any audio equipment with digital input (CD
Recorder, Digital Audio Tape [DAT] deck, Digital
to Analogue Conver ter and Digital Signal
Processor, for example). Use a cinch cable to
connect the DIGITAL OUT terminal to the
digital input terminal of the equipment.
Inserting batteries into the
remote control
Insert two batteries (Type R06 or AA) into the
remote control with the correct polarity as
indicated by the + and - symbols inside the
battery compar tment.
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.
Preparations
Rear connections
The type plate is located at the rear of the
system.
For users in the U.K.: please follow the
instructions on page 2.
A Pow er
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 connections with
the power switched on.
To avoid overheating of the system, a safety
circuit has been built in. Therefore, your
system may switch to Standby mode
automatically under extreme conditions. If
this happens, let the system cool down
before reusing it.
B 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
Position the antenna as far as possible from a TV,
VCR or other radiation source.

SERVICE POSITIONS & REPAIR HINTS
1) During repair it is possible to disconnect the ECO6 Tuner board, ETF8 Tape Module and/or 3DTC Module completely unless the fault is suspected to be in that area. This will not affect the performance of the rest of the set.
2) Use Service position A for repairs on Combi or Mains Board.
3) Use Service position B for repairs on Tuner or 3DTC electronic.
4) Use Service position C for repairs on the ETF8 Tape module.
Note: The flex cables are very fragile, care should be
taken not to damage them during repair. After repair, be very sure that the flex cables are inserted properly into the flex sockets before encasing, otherwise faults may occur.
