26、Fans.CN Adjustments Digital Audio Broadcasting (DAB) The DAB module (type 2203) for the BeoCenter 2 Socket Unit will automatically adapt to the band and frequency table preprogrammed in the application software for the particular Socket Unit type number. If the band and frequency table setup from th

27、e factory do not correspond to the particular country where it is used, the PC-based ServiceTool program must be used. DAB aerial Select a channel transmitting a DAB mutiplex signal.
