Abstract (en)

[origin: EP0590337A1] The invention relates to a method for operating a radio clock (FU) consisting of a crystal-controlled clock (QU) which is synchronized with a time-mark signal by means of a time-mark receiver (ZE) via a signal processor (SP). In a joint arrangement having a further device (G1), for example a computer or a television set, the reception of the time-mark signal is generally largely suppressed because of the interfering effects of the further device (G1). Consequently, in the case of the method according to the invention the synchronization of the quartz-controlled clock (QU) with the time-mark signal is performed exclusively when the further device (G1) does not generate an interference field. For this purpose, a detector (DS) is provided which detects the operating state of the further device and permits the quartz clock (QU) to be synchronized with the time-mark signal only if the further device (G1) generates no interference field or a reduced interference field. Also described is a radio clock which is suitable for operation using the method according to the invention. <IMAGE>
