  Then, when the control unit 202 receives the transmission output restriction signal by human body communication from the strap 100 (S101, Yes), the control unit 202 proceeds to step S103. When the control part 202 has not received the transmission output restriction signal by human body communication (S101, No), it shifts to Step S101.

  When the control unit 202 receives the transmission output restriction signal by human body communication, the control unit 202 notifies the communication device 104 of the restriction of transmission output via the wireless unit 214 (step S103), and proceeds to step S105. .

  The control unit 202 determines whether an error notification has been received from the communication device 104 via the wireless unit 214. If an error notification has been received (step S105, Yes), the process proceeds to step S107, and if an error notification has not been received (step S105, No), the process proceeds to step S109.

  When the control unit 202 receives an error notification from the communication device 104, the control unit 202 causes the LEDs provided in the notification unit 210 to emit light at predetermined time intervals. Accordingly, the control unit 202 notifies the user that an error notification has been received from the communication device 104 (step S107), and the process proceeds to step S109.

  Then, when the transmission output restriction signal is received (step S201, Yes), the control unit 302 proceeds to step S203. If the control unit 202 has not received the transmission output restriction signal (S201, No), the control unit 202 proceeds to step S201.

  If the control unit 302 receives the transmission output restriction signal, the control unit 302 restricts the transmission output of the wireless unit 314 (step S203), and the process proceeds to step S205. Note that the limitation of the wireless transmission output by the control unit 302 is the OFF of the wireless output. However, in the present embodiment, the transmission output may be reduced (for example, 50% off) as a limitation on the wireless transmission output by the control unit 302.

  The control unit 302 determines whether a transmission error to the base station 106 has occurred. The determination as to whether or not this transmission error has occurred may be the same as the determination as to the handover processing. For example, the control unit 302 monitors transmission errors based on the retransmission request from the base station 106, and performs handover with five transmission failures for control messages and 12 transmission failures for data. Therefore, when the handover condition is satisfied, the control unit 302 determines that a transmission error requiring notification has occurred to the user (Yes in step S205), and the process proceeds to step S207. If a transmission error has not occurred (No at Step S205), the control unit 302 proceeds to Step S209.

  When a transmission error occurs, the control unit 302 transmits an error notification to the clock 102 via the communication unit 308 (step S207), and proceeds to step S209.

  The control unit 302 detects whether a transmission output restriction signal is received from the clock 102 via the communication unit 208 (step S209).

  Then, when the transmission output restriction signal is received (step S209, Yes), the control unit 202 proceeds to step S205. If the control unit 202 has not received the transmission output restriction signal (No at step S209), the control unit 202 proceeds to step S211.

  If the control unit 302 does not receive the transmission output restriction signal (No at step S209), the control unit 302 instructs the wireless unit 314 to release the restriction on transmission output (step S211), and ends the process.
