Further, the first display control unit 44 controls the first display unit 26 to turn on a predetermined second type of lighting when the radio wave intensity of the first signal is equal to or less than the first threshold value.
　第１表示部２６は、第１表示制御部４４の制御に応じて点灯をする。従って、第１表示部２６は、第１信号の電波強度が第１しきい値より大きい場合、第１の種類の点灯をし、第１信号の電波強度が第１しきい値以下である場合、第２の種類の点灯をする。これにより、第１表示部２６は、第１装置から第１しきい値より大きい電波強度の信号を受信ができることをユーザに提示することができる。 The first display unit 26 lights up according to the control of the first display control unit 44. Therefore, when the radio field intensity of the first signal is greater than the first threshold value, the first display unit 26 lights up the first type, and when the radio wave intensity of the first signal is equal to or less than the first threshold value. , Turns on the second type of lighting. As a result, the first display unit 26 can present to the user that a signal having a radio wave intensity higher than the first threshold value can be received from the first device.
　なお、第１表示制御部４４は、第１信号の電波強度が第２しきい値より小さい場合、第１表示部２６が予め定められた第３の種類の点灯をするように制御してもよい。この場合、第１表示部２６は、第１信号の電波強度が第２しきい値より小さい場合、第３の種類の点灯をする。なお、第２しきい値は、第１しきい値より小さい。これにより、第１表示部２６は、第１装置から十分な電波強度の信号を受信ができていないことをユーザに提示することができる。 Even if the first display control unit 44 controls the first display unit 26 to light a predetermined third type when the radio field intensity of the first signal is smaller than the second threshold value. good. In this case, the first display unit 26 lights a third type when the radio field intensity of the first signal is smaller than the second threshold value. The second threshold value is smaller than the first threshold value. As a result, the first display unit 26 can indicate to the user that the signal of sufficient radio wave strength has not been received from the first device.
　第２表示制御部４６は、第２検出部４０により検出された第２信号の電波強度に基づき、第２表示部２８の表示を制御する。第２表示制御部４６は、第２信号の電波強度が、予め定められた第１しきい値より大きい場合、第２表示部２８が第１の種類の点灯をするように制御する。また、第２表示制御部４６は、第２信号の電波強度が第１しきい値以下である場合、第２表示部２８が第２の種類の点灯をするように制御する。 The second display control unit 46 controls the display of the second display unit 28 based on the radio wave intensity of the second signal detected by the second detection unit 40. The second display control unit 46 controls the second display unit 28 to turn on the first type when the radio wave intensity of the second signal is greater than the predetermined first threshold value. Further, the second display control unit 46 controls the second display unit 28 to turn on the second type when the radio wave intensity of the second signal is equal to or less than the first threshold value.
　第２表示部２８は、第２表示制御部４６の制御に応じて点灯をする。従って、第２表示部２８は、第２信号の電波強度が第１しきい値より大きい場合、第１の種類の点灯をし、第２信号の電波強度が第１しきい値以下である場合、第２の種類の点灯をする。これにより、第２表示部２８は、第２装置から第１しきい値より大きい電波強度の信号を受信ができることをユーザに提示することができる。 The second display unit 28 lights up according to the control of the second display control unit 46. Therefore, when the radio field intensity of the second signal is greater than the first threshold value, the second display unit 28 lights up the first type, and when the radio wave intensity of the second signal is equal to or less than the first threshold value. , Turns on the second type of lighting. As a result, the second display unit 28 can present to the user that a signal having a radio wave intensity higher than the first threshold value can be received from the second device.
　なお、第２表示制御部４６は、第２信号の電波強度が第２しきい値より小さい場合、第２表示部２８が第３の種類の点灯をするように制御してもよい。この場合、第２表示部２８は、第２信号の電波強度が第２しきい値より小さい場合、第３の種類の点灯をする。なお、第２しきい値は、第１しきい値より小さい。これにより、第２表示部２８は、第２装置から十分な電波強度の信号を受信ができていないことをユーザに提示することができる。 Note that the second display control unit 46 may control the second display unit 28 to turn on the third type when the radio wave intensity of the second signal is smaller than the second threshold value. In this case, the second display unit 28 lights the third type when the radio field intensity of the second signal is smaller than the second threshold value. The second threshold value is smaller than the first threshold value.

The communication device 10 may be assigned to the second device. In this case, the user operates the target communication device 20 to start the measurement mode in the vicinity of the first candidate or the second candidate that is desired to be set as the first device. Thereby, the target communication device 20 can make the user recognize which of the first candidate and the second candidate determined in S11 and S12 is the first device.
　続いて、Ｓ１４において、ユーザは、対象通信装置２０を対象エリア内に仮配置する。 Subsequently, in S14, the user temporarily arranges the target communication device 20 in the target area.
　続いて、Ｓ１５において、ユーザは、第１表示部２６および第２表示部２８を確認する。Ｓ１５で第１表示部２６および第２表示部２８を確認した結果、第１装置および第２装置の一方または両方からの信号の電波強度が第１しきい値以下である場合、ユーザは、処理をＳ１４に戻す。そして、Ｓ１４において、ユーザは、対象通信装置２０を異なる位置に仮配置し、再度処理を繰り返す。 Subsequently, in S15, the user confirms the first display unit 26 and the second display unit 28.
