For servicing CDR8xx the set has to be divided into two parts:1. Except for the CD-R/W module all workshops can repair the set on component level.The Switched Mode Power Supply unit will be exchanged completely in case of a failure.2.The CD-R/W module can only be repaired on component level with the help of ComPair.With this tool diagnosing of the set can be done in an interactive way. In this tool also the adjustment procedure hasbeen implemented. The adjustment is absolutely necessary in case the CDR-Main Board and/or CD drive (CDR Loader)is disconnected from the matched production combination.Only designated workshops can perform these repairs!Please send the complete set to the designated workshop.Available circuit descriptions: The Basics of Compact Disc Recordable/Rewritable 4822 725 252423rd generation Compact Disc Recording 3104 125 40100(with reference to description of the Basic Engine)2nd line Service Manual CDR Mozart Module 3122 785 60030 chapterTechnical Specification and Measurement setup.1-1, 1-2Location of printed circuit boards.1-3Warnings 20 26 52PAUSE20 26 48SHUFFLE 20 26 28REPEAT 20 26 29CD1 20 20 55CD2 20 20 56CD3 20 20 57CDR 26 26 63RC5 code RC283505, 130300Remote Control: RC5 commands RC283505TECHNICAL SPECIFICATIONLRLEVEL METERe g.

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.
