Der Original zustand des Geräts darf nicht verändert werden;für Reparaturen sind Original-Ersatzteile zu verwenden.ILe norme di sicurezza esigono che lapparecchio venga rimessonelle condizioni originali e che siano utilizzati i pezzi di ricambioidentici a quelli specificati.“After servicing and before returning set to customer perform aleakage current measurement test from all exposed metal parts toearth ground to assure no shock hazard exist. The leakage currentmust not exceed 0.5mA.“ESD & SAFETY INSTRUCTIONBDISASSEMBLY INSTRUCTIONS2-1Dismantling the Grill Base & Speaker Driver1. Place the Subwoofer Box as shown in the Picture 1and use a screw driver to force open the Grill Base.Caution: Take care the surface when take out theGrill Base of Subwoofer2.
