After the operator enters the nickname of the partner station in the name column and touches the “Add” button B3, the partner station data including the call sign is additionally registered in the list.

  When the operator wants to communicate with the personal station displayed in FIG. 6B, the dialog box D3 in FIG. 6C is opened and the “[TO] Personal station setting” frame is touched with a finger. The data of the partner station including the call sign is transmitted to the control unit 13 of the wireless device 1 by the unit 71 and stored in the storage unit 17 as destination data.

  Although not displayed in the map of FIG. 6, when there is a repeater icon R near the personal station icon Y set as the transmission destination, this repeater is performed by the same procedure as described with reference to FIG. Can be set as a destination repeater, and data necessary for communication can be transmitted to the wireless device 1 and stored in the storage unit 17.

  When the user communicates with the partner station set on the information terminal 7 using the repeater set on the information terminal 7, the data already stored in the storage unit 17 of the wireless device 1 when the communication is set That is, the call signs of the destination repeater, the source repeater, the transmission destination, and the transmission source are stored. Further, the storage unit 17 stores a table T in which repeater information shown in FIG. 3 is described. Accordingly, the communication can be started simply by the user operating the operation unit 15 and reading these data from the storage unit 17.

  In addition, in FIG. 6, the case where the personal station near the radio device 1 is set as the communication partner station has been described. On the other hand, if you select a partner station for communication from the registered partner station list, acquire map information based on the location information of that partner station, and select a destination repeater from the repeaters displayed on the map, Settings for communication can be performed in the same procedure as described above. However, in this case, it is assumed that the other station is not moving as in the case where a wireless device is installed at home.

  As described above, in the conventional wireless device 1, data such as a call sign of a transmission source necessary for communication is input by characters and numerical values in the operation unit 15, and setting operation at the time of communication is performed. It was complicated. On the other hand, when the information terminal 7 is used as an input interface as in the present invention, the data required for communication can be transferred to the wireless device 1 simply by repeating a simple operation of touching an icon or a character displayed on the screen. Therefore, the setting operation can be greatly simplified.

  In the present embodiment, the repeater table T shown in FIG. 3 and the above-described partner station list are also stored in the storage unit 17 of the wireless device 1. The station data is transmitted to the wireless device 1. The data transmitted to the wireless device 1 is added to the counterpart station list stored in the storage unit 17 under the control of the control unit 13.

  As described above, the table T and the partner station list having the same contents are stored in the storage unit 17 of the wireless device 1 and the storage unit 75 of the information terminal 7 without using the information terminal 7 as an input interface of the wireless device 1. This is to prevent any trouble in communication when using the radio alone.

  In this embodiment, from the viewpoint of operability and portability, the wireless communication modules 14 and 76 are used to realize mutual communication between the wireless device 1 and the information terminal 7. However, the wireless device 1 and the information terminal 7 are used. Needless to say, they may be connected to each other by a wired connection.
