WARNING
GB
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.
F
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
D
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
NL
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.
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 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.
GB
Safety regulations require that the set be restored to its original condition and that parts which are identical with those specified, be used.
NL
Veiligheidsbepalingen vereisen, dat het apparaat bij reparatie in zijn oorspronkelijke toestand wordt teruggebracht en dat onderdelen, identiek aan de gespecificeerde, worden toegepast.
F
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.
D
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.

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 mays witch to Standby mode
automatically under extreme conditions. If
this happens, let the system cool down
before reusing it (not available for all versions).

PREP ARATIONS AND CONTROLS
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:
1
Remove fuse cover and fuse.
2
Fix new fuse which should be a BS1362 5 Amp,
A.S.T.A. or BSI approved type.
3
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 elsewhere.
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.

3) During repair it is possible to disconnect the Tuner board and CDC Module completely unless the fault is sus­pected to be in that area. This will not affect the performance of the rest of the set.
4) Due to the short flex cable wires in the ETF Module, the pc board should be disconnected and reconnected on the reverse side of the tape mechanism to keep it electrically connected during repair. See picture 3.
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 occurs.

Error Description Focus Error
Triggered when the focus could not be found within a certain time when starting up the CD or when the focus is lost for a certain time during play.
Radial Error Triggered when the radial servo is off-track for a certain time during play.
Sledge In Error The sledge did not reach its inner position (inner-switch is still close) before approximately 6 Sec. have passed by. Inner-switch or sledge motor problem.
Sledge Out Error The sledge did not come out of its inner position (inner-switch is still open) before approximately 250 mSec. have passed by. Inner-switch or sledge motor problem.
Jump-offtrack error Triggered in normal play when the jump destination could not be found within a certain time. When this error occurred, software will try to recover by initiating the jump command again. If it is recoverable, the disc will continue to play.
Subcode Error Triggered when a new subcode was missing for a certain time during play.
PLL Error The Phase Lock Loop could not lock within a certain time.
Turntable Motor Error Generated when the CD could not reached 75% of speed during startup within a certain time. Discmotor problem.
Focus Search Error The focus point has not been found within a certain time.
The carousel switch is not open within certain time. This can happen when either the switch is defective and closed all the time, or when the carousel is blocked when located exactly at a disc position.
The carousel position switch did not close within a certain time. This can happen when the switch is defective and never closes electrically, or when the carousel is blocked in between two disc positions. The time-out is approximately 5 Sec.
The drawer could not enter the inside position is opening again. This can be caused because the drawer is blocked by something and cannot go fully inside, or the drawer switch is defective and does not close.
