Radio controlled timepiece |
摘要 |
A radio controlled timepiece includes: a radio wave receiving section which outputs a time code signal; an indicator display section which performs a display regarding a reception condition; a level change detecting section which detects a change of a signal level of the time code signal in a predetermined detection interval in a period of 1 second; an indicator control section which controls a content of the display based on a number of times that the change of the detected signal level appears; and an interval setting section which specifies the detection interval as a whole interval of the period of 1 second during a detecting process of a synchronization point in the time code signal every 1 second, and narrows the detection interval to be a certain interval within the period of 1 second after a detection of the synchronization point every 1 second.
