Abstract (en)
[origin: EP0909996A2] The solar-powered radio clock (11) has a power store (210 for operating inter alia an electromechanical transducer (15) for the time display (12). A step monitor (25) triggers an at least partial restart of the radio clock in the event of a shortened or interrupted drive pulse caused by an inadequate state of charge of the power store.
