HANDLING CHIP COMPONENTS

1-1

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, 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.

d

Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten. Der Originalzustand des Ger ätes darf nicht ver ändert werden. F ür Reparaturen sind Originalersatzteile zu verwenden. Sicherheitsbauteile sind durch das Symbol markiert.

SAFETY

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.

Selected frequency grid is stored in the EEPROM.

2)

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:

This test functions only with the East European tuner version used in /14/34 set versions. The test was executed on every set in the production line. In case the discriminator filter or the EEPROM has to be exchanged the automatic IF-offset correction should also be executed after repair.

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 d isplay shows "00E".  When the same difference is found twice the value will be s tored as offset. The actual used offset is shown on the display ( -3, -2, -1, 0, 1, 2, 3 ).
