  For example, if you use a wireless earphone microphone at a coffee shop and leave it as it is, if you store the location information and time at the time of alarm warning due to deterioration of communication quality, you will not notice the alarm by alarm Even if it is lost, the location information and time information stored when the loss is noticed is displayed, so that you can see that the wireless earphone microphone was misplaced in the coffee shop. Search can be performed.

  The alarm means includes display, warning sound, storage, notification to other devices (e-mail, etc.) and the like. The condition to reach the alarm is when the communication quality is deteriorated or disconnected, but when the mobile external device 2 has a voltage drop alarm function, the communication is performed when the voltage is not lowered and the power is not turned off. You may limit only when quality deteriorates rapidly and it becomes communication disconnection. Thereby, even when the power of the mobile external device 2 is turned off or the battery is exhausted, it is possible to prevent a malfunction that causes an alarm. Even in the event that it is lost, since the rough location information and time can be known from the stored information, the lost mobile external device 2 can be easily searched.

Furthermore, in the present invention, when the communication with the mobile external device 2 is disconnected and the no-operation state has passed for a certain time or more, it is regarded as a lost state, an alarm warning is issued, and the mobile external device 2 cannot be operated. Settings can also be made.
