ON / OFF of the time adjustment function for the external device is set (S1002). If it is set to ON, it is in a standby state until a predetermined time (for example, 4 minutes) before the time set in step S1001 (S1003). The time setting signal is detected from the digital broadcast radio wave received by the tuner unit 11 and extracted as time setting data, and is set as the current time in the time management unit of the setting-side electronic device 10 (S1004). After that, a standby state is set until the reserved time for time adjustment set in step S1001 is reached (S1005). When the reserved time is reached, the current time set in step S1004 is converted into a tone sound as time adjustment data, and the sound output unit Output is performed (S1006).
