Abstract:
1. A radio controlled timepiece comprising: a radio wave receiving section which receives a standard radio wave to output a time code signal; an indicator display section which performs a display regarding a reception condition of the standard radio wave; a level change detecting section which detects a change of a signal level of the time code signal outputted from the radio wave receiving section in a predetermined detection interval in a period of 1 second; an indicator control section which controls a content of the display by the indicator display section based on a number of times that the change of the predetermined signal level detected by the level change detecting section appears; and an interval setting section which specifies the detection interval for the level change detecting section 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 for the level detecting section to be a certain interval within the period of 1 second after a detection of the synchronization point every 1 second.
