PURPOSE: To obtain a time resetting circuit for a timer provided in an electronic product which receives a broadcasted signal directly. CONSTITUTION: A receiving means for receiving a broadcasted signal containing a specific frequency, a specific frequency detecting means for detecting the specific frequency from the receiving means, and a counting means for counting the number of pulses detected by the specific frequency detecting means are provided, and every time of a timer provided in an electronic product is reset accurately. Consequently, it becomes possible to reset every time of the timer accurately. |
