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 d´autres semi-conducteurs sontsensibles aux décharges statiques (ESD). Leur longévitepourrait être considérablement écourtée par le fait qu´aucuneprécaution nést prise à leur manipulation.Lors de réparations, s´assurer de bien être relié au mêmepotentiel que la masse de l´appareil et enfileer le braceletserti d´une résistance de sécurité.Veiller à ce que les composants ainsi que les outils que l´onutilise 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.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 symboliLe norme di sicurezza estigono che l´apparecchio vengarimesso nelle condizioni originali e che siano utilizzati ipezzi di ricambiago identici a quelli specificati.Componenty di sicurezza sono marcati conVeiligheidsbepalingen vereisen, dat het apparaat in zijnoorspronkeliijke toestand wordt teruggebracht en datonderdelen, identiek aan de gespecificeerde, worden toegepast.De Veiligheidsonderdelen zijn aangeduid met het symbools Varning !Osynlig laserstrålning när apparaten är öppnad ochspärren är urkopplad.

The dot-marked instructions are not necessary for the required operation.All instructions in this manual are based on control via the keys on the set. If there are corresponding keys available on the remote control they can be used as well. All redundant packing material has been omitted. Wehavedone our utmost to make the packaging easily separable into three mono materials: cardboard (box), polystrene foam (buffer) and polyethylene (bags, protective foam sheet). Your set consists of materials which can be recycled ifdisassembled by a specialized company. Please observe thelocal regulations regarding the disposal of packing materials, exhausted batteries and old equipment.
