[Operation during voice communication]
Next, an operation when the mobile phone 10 is performing voice communication will be described.
When voice communication is being performed by the mobile phone 10, a screen indicating that voice communication is being performed is displayed on the display unit 111 as shown in FIG. Here, when an earthquake occurs and the central device 21 generates information indicating a message that notifies the occurrence of the earthquake and information indicating a message that calls attention to the disaster, the generated information is transmitted to the disaster prevention radio base station. The stations 22A to 22C are converted into disaster prevention radio signals and output.

  When the disaster prevention radio signal output from the disaster prevention radio base station 22A is received by the second communication unit 108 of the mobile phone 10 (step SA1), the second communication unit 108 displays information (earthquake information) represented by the received disaster prevention radio signal. A message notifying the occurrence and a message for calling attention to a disaster) are converted into digital data (step SA2) and output to the CPU 102 and the display driver unit 110.

  The control circuit 110A analyzes the input digital data, and generates display data for displaying information represented by the digital data, that is, a message for notifying the occurrence of an earthquake and a message for calling attention to a disaster ( Step SA3) Store in the memory 110D. When the storage of the display data is completed, the control circuit 110A controls the scanning line driving circuit 110B and the data line driving circuit 110C according to the display data (step SA4) and turns on the backlight (step SA5), and is stored in the memory 110D. The information represented by the display data is displayed on the display unit 111. As a result, as shown in FIG. 4, a message notifying the occurrence of an earthquake and a message for calling attention to a disaster are displayed on the display unit 111.

  When the user of the mobile phone 10 ends the voice call and looks at the display unit 111, the message shown in FIG. 4 is displayed on the display unit 111, so that the occurrence of the earthquake can be known. When the CPU 102 receives the digital data output from the second communication unit 108, the CPU 102 may control the first communication unit 107 to stop the voice communication.

[Operation when the power is turned off]
Next, the operation when the mobile phone 10 is turned off will be described. In addition, since the operation | movement until an emergency radio signal is output from each disaster prevention radio base station after an earthquake occurs is the same as the operation | movement mentioned above, The description is abbreviate | omitted.
