HANDLING CHIP COMPONENTS 1-1
PCS 104 439
© 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 d écharges statiques (ESD). Leur long évite
pourrait être consid érablement écourt ée par le fait qu ´aucune
précaution n ést prise à leur manipulation.
Lors de r éparations, s ´assurer de bien être reli é au m ême
potentiel que la masse de l ´appareil et enfileer le bracelet
serti d ´une r ésistance de s écurit é.
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
gegen über elektrostatischen Entladungen (ESD).
Unsorgf ältige Behandlung im Reparaturfall kann die
Lebensdauer drastisch reduzieren.
Sorgen Sie daf ür, da ß Sie im Reparaturfall über ein Puls-
armband 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 reparat ie
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 scar iche
statiche (ESD).
La loro longevit à potrebbe essere fortemente ridatta in caso di
non osservazione della pi ù 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.
©
Safety regulations require that the set be restored to its
original condition and that parts which are identical with
those specified be used.

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.
AVOID DIRECT EXPOSURE TO BEAM.

CONNECTIONS AND CONTROLS
For the set (optional) Open the battery compartment of the set and insert 6 batteries, type R20, UM-1 or D-cells (preferably alkaline). For the remote control (optional) Open the battery compartment of the remote control and insert 2 batteries, type R03, UM-4 or AAA-cells (preferably alkaline). Remove batteries if they are flat or if the set is not going to be used for a long time. Batteries contain chemical substances, so they should be disposed of properly. 1Check whether the mains voltage as shown on the type plate
corresponds to your local mains voltage. If it does not, consult your dealer or service organisation. The type plate is located on the bottom of the set.
2If the set is equipped with a VOLTAGE selector A, set this
selector to the local mains voltage.
3Connect the mains cable to the AC MAINS socket and the wall
socket. This switches on the mains supply. The mains cable is inside the battery compartment.
The battery supply will be switched off when the set is connected to the mains. To change over to battery supply, pull out the plug from the unit’s AC MAINS socket. To disconnect the set from the mains completely, remove the mains plug from the wall socket.

Set the POWER slider to the desired sound source: CD, TAPE, or BAND (for radio). The set is switched off when the POWER slider is set to OFF/TAPE and the keys of the tape deck are released. Note: If you use batteries, switch the set off after use. This will
avoid unnecessary power consumption.
Adjust the volume using the VOLUME control. Increase and decrease the bass level by pressing DBB. The bass level can also be emphasised if you place the set against wall or shelf. Do not cover any vents; leave sufficient room around the unit for ventilation. 1Set the POWER slider to FM or MW to select the desired
wave band.
2Tune to the desired radio station by using the TUNING wheel. Improving RADIO reception For FM stations, pull out the telescopic antenna. To improve the signal, incline and turn the antenna. Reduce its length if the signal is too strong (very close to a transmitter). For MW stations, direct the built-in antenna by turning the whole set. The telescopic antenna is not needed.

This deck is not suitable for recording on cassettes of the type CHROME (IEC type II) or METAL (IEC type IV). The recording level is set automatically. The controls VOLUME and DBB do not affect the recording. At the very beginning and end of the tape, no recording will take place in the 7 seconds during which the leader tape passes the recorder heads. Protecting tapes from accidental erasure Keep the cassette side to be protected in front of you and snap off the left tab. Now, recording on this side is no longer possible. To record again on this side of the cassette, cover the opening with a piece of adhesive tape.

Door switch is ignored Æ CD door can be opened.
Slide servo, Radial servo, Focus servo, Disc motor

Mute is switched on via decoder IC.
Purpose of RADIAL test:
To check if the Audio signal is reproduced.
Subcode info is ignored during this test Æ
If the CD player functions well in this testmode,
but not in the normal Play mode check quality
of the eye-pattern signal.

Error number Error type
Error type:
Error description
E0 Focus Error
Triggered when the focus is lost for more than 250ms during playing the CD.
E6 Subcode Error
No valid subcode for 300ms during PLAY.
E3 Slide-out error
Generated when the inner-switch did not open within approx. 250ms when the pick up is
moved from the inner position outside. Inner-switch or slide motor problems.
E2 Slide-in error
Generated when the inner-switch did not close within approx. 4s when the pick up is
moved inside. Inner-switch or slide motor problems.
W
F0 Focus Search Error
Triggered when the focus could not be found within 3s when starting up the CD. F
W

F2 Fatal Subcode Error
No valid subcode for more than 4s during PLAY.F

W = Warning Æ
F = Fatal Error Æset stops operation, message remains on the display.
CD ERROR codes
table 1
(The set can only be operated again via a reset)
E5 Jump error.
Triggered when the servo processor counts too less tracks in a defined time during JUMPS.
This can be caused by a disturbed HF-signal (the tracks cannot be recognized exactly),
slide motor problems, track servo problems or scratched discs.
E7 PLL lock error
When the PLL did not lock after 10 retries then this warning message is generated and
the servo is stopped and restarted (as if the user would have pressed STOP and then
PLAY immediately) to recover.
