Module exchange is possible On-site, at the dealer or in the service workshop whatever is most convenient in each case. For On-site service a Back-up suitcase must be used. Module exchange This way of servicing is recommended, due to the fact that most of the modules are multilayer based, and most of the circuits are on a single main PCB. For On-site service it is possible to order a Back-up suitcase. Microcomputer If the main PCB is replaced, the entire identity of the set is maintained (security code included). If the main PCB is suffering from an intermittent fault, the display can read out error codes in test mode. CD mechanism exchange The CD-PRO II mechanism can be changed on-site or in service centres. Both the CD-mechanism and the servo/decoder PCB are one single unit for easy replacement and future update. There is easy access for cleaning the lens, and by means of test modes most fault symptoms are identifi ed. Turntable gearbox The gearbox which loads the CD is a block module and must be changed as a complete part. FM antenna The antenna module can be replaced on-site. Speakers All speakers can be replaced (placed behind the removable front cover). There is simple sound level adjustment via the display. Amplifi er Part of the main PCB. The only adjustment necessary after module exchange is the speaker sound level. Read out the values for adjustment (in test mode) before replacing the module - if possible.

Exchange of PCB1 and PCB3 Radio/CD/LF/P module The exchange module PCB1 (Radio/CD/LF/P) contains a special and individual “digital exchange-code” due to theft protection. Therefore if it is not possible to use a PCB1 from an other BeoSound1 during service. It is possible to try out the new module for 12 hours ON-time or until the PIN code is used. After 12 hours the Radio/CD/LF/P module is named to the product and cannot be used in an other product, because the “digital exchange-code” has been transferred to the P the module and must go back to Bang SHIFT in der “Liste” suchen und dann folgende Sequenz eingeben: 9 0 2 5 8 Anschlieend befi ndet sich das Gert im Testmodus und fragt mit zwei Displaystellen nach der TM-Nr.
