HANDLING CHIP COMPONENTS
© WARNING
All Cs 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 C 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 Cs 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 Puls-
armband mit Widerstand mit dem Massepotential des
Gerätes verbunden sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem
Potential.
ñ WAARSCHUWING
Alle C´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 C 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.
©
Safety regulations require that the set be restored to its
original condition and that parts which are identical with
those specified be used.

Mains Supply Whenever convenient,use the mains supply if you want to conserve battery life. Make sure you remove the plug from the set and wall outlet before inserting batteries. Batteries (not included)
1Open the battery compartment and insert
six batteries, type R-14,UM-2 or C-cells, (preferably alkaline) with the correct polarity as indicated by the "+" and "–" symbols inside the compartment.
2Close the compartment door,and make
sure the batteries are firmly and correctly in place.The set is now ready to operate. ➜If BATT LOW lights up,battery power
is running low.The BATT LOW indicator eventually goes out if the batteries are too weak.
Batteries contain chemical substances, so they should be disposed of properly. Incorrect use of batteries can cause electrolyte leakage and will corrode the compartment or cause the batteries to burst.Therefore:
• 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.
• Remove the batteries if the set is not to be
used for a long time.
UsingAC Mains
1 Check if the mains voltage, as shown on
the type plate located on the bottom of the set,corresponds to your local mains supply. If it does not,consult your dealer or service centre.
2 Connect the mains cord to the AC MAINS
inlet and the wall outlet.The mains supply is now connected and ready for use.
3 To switch off completely,unplug the mains
cord from the wall outlet.
• Unplug the mains cord from the wall outlet
to protect your set during heavy thunderstorms. The type plate is located on the bottom of the set.
Switching power on/off: Save energy Whether you are using mains or battery supply, to avoid unnecessary energy consumption always adjust the POWER slider to TAPE/OFF and check if the
cassette keys are released.

•Cleaning of the heads can also be done by
playing a cleaning cassette through once. CD player and disc handling
•The lens of the CD player should never be
touched!
•Sudden changes in the surrounding
temperature can cause condensation to form and the lens of your CD player to cloud over.Playing a disc 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 keep the CD
compartment dust-free.To clean,dust the compartment with a soft dry cloth.
•To take a disc out of its box,press the
centre spindle while lifting the disc.Always pick up the disc by the edge and replace the disc back in its box after use to avoid scratching and dust.
•To clean the disc,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 disc or attach any stickers
to it.

In sets with 30kHz grid on FM band it may occur that the
tuned frequency is indicated wrong on the display because
of tolerances of the discriminator filter.
For that reason the testsoftware is prepared for an
automatic IF-offset correction.
Note:
To execute the automatic IF-offset correction proceed as follows:
* feed a strong 87.5MHz signal to the antenna
* press the PLAY button
The µP starts now several times the search mode.
If the transmitter was found at 87.5MHz the stop-frequency sent by the
radio IC is compared with the nominal frequency else the display shows "00E".
 When the same difference is found twice the value will be stored as offset.
The actual used offset is shown on the display ( -3, - , -1, 0, 1, , 3 ).
