First, you have to check the versions of the software and hardware devices and By-me control unit installed. The control unit will have to undergo a major software upgrade (carried out by your local Technical Assistance Centre) that will enable Sound system configuration, but may at the same time cause incompatibilities with older products. Upgrading these incompatible devices are at the expense of the customer. You should contact the Vimar number 0424 488500 to individually address your specific situation.
