Zusammenfassung:	Operation of a plurality of electronic devices is synchronized. The plurality of devices include a master unit and a plurality of other units, and the master unit transmits a synchronizing signal to at least one of the other units at predetermined intervals. Each of at least two of the other units detects whether a synchronizing signal is received at the respective unit within a predetermined period of time. If not, the respective unit changes from a slave mode of operation to a master mode of operation. Contention between the two or more potential back-up master units is resolved based on priority in a daisy-chain arrangement or by providing different time-out watch-dog periods for the potential back-up devices.
