© WARNINGAll ICs and many other semiconductors are susceptible toelectrostatic discharges (ESD). Careless handling duringrepair can reduce life drastically.When repairing, make sure that you are connected with thesame potential as the mass of the set via a wristband withresistance. Keep components and tools at this potential.

f ATTENTIONTous les IC et beaucoup dáutres semi-conducteurs sontsensibles aux décharges statiques (ESD). Leur longévitepourrait être considérablement écourtée par le fait quáucuneprécaution nést prise à leur manipulation.Lors de réparations, sássurer de bien être relié au mêmepotentiel que la masse de láppareil et enfileer le braceletserti dúne résistance de sécurité.Veiller à ce que les composants ainsi que les outils que lónutilise soient également à ce potentiel.

d WARNUNGAlle ICs und viele andere Halbleiter sind empfindlichgegenüber elektrostatischen Entladungen (ESD).Unsorgfältige Behandlung im Reparaturfall kann dieLebensdauer drastisch reduzieren.Sorgen Sie dafür, daß Sie im Reparaturfall über ein Puls-armband mit Widerstand mit dem Massepotential desGerätes verbunden sind.Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesemPotential.

ñ WAARSCHUWINGAlle IC´s en vele andere halfgeleiders zijn gevoelig voorelectrostatische ontladingen (ESD).Onzorgvuldig behandelen tijdens reparatie kan de levensduurdrastisch doen vermindern. Zorg ervoor dat u tijdens reparatievia een polsband met weerstand verbonden bent met hetzelfdepotentiaal als de massa van het apparaat.Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.

i AVVERTIMENTOTutti IC e parecchi semi-conduttori sono sensibili alle scarichestatiche (ESD).La loro longevità potrebbe essere fortemente ridatta in caso dinon osservazione della più grande cauzione alla loromanipolazione. Durante le riparationi occorre quindi esserecollegato allo stesso potenziale che quello della massadelápparecchio tramite un braccialetto a resistenza.Assicurarsi che i componenti e anche gli utensili con quali silavora siano anche a questo potenziale.

©Safety regulations require that the set be restored to itsoriginal condition and that parts which are identical withthose specified be used.Safety components are marked by the symbol

SERVICE POSITIONS & REPAIR HINTS

1) During repair it is possible to disconnect the ECO6Tuner board, ETF8 Tape Module and/or 3DTC Modulecompletely unless the fault is suspected to be in thatarea.This will not affect the performance of the rest of the set.

2) Use Service position A for repairs on Combi or MainsBoard.

3) Use Service position B for repairs on Tuner or 3DTCelectronic.

4) Use Service position C for repairs on the ETF8 Tapemodule.Note: The flex cables are very fragile, care should be

taken not to damage them during repair. Afterrepair, be very sure that the flex cables areinserted properly into the flex sockets beforeencasing, otherwise faults may occur.

1) If sensitivity of frequency counter is too low adjust to max. channel separation (input signal: stereo left 90% + 9%, adjust output on right channel to minimum)2) RC network serves for damping the IF-filter while adjusting the other one.3) For AM RF adjustments the original frame antenna has to be used!
