Zusammenfassung:PROBLEM TO BE SOLVED: To easily find an installation position suitable for a relay.SOLUTION: A slave unit 2 capable of wirelessly communicating directly or via a relay 3 with a master unit 1 which transmits a radio wave includes: a radio wave intensity acquisition part 241 for acquiring first radio wave intensity as the intensity of a radio wave received from a master unit 1 at a first position and second radio wave intensity as the intensity of a radio wave received from the relay 3 installed at a second position farther from the master unit 1 than the first position at the first position; an estimation part 243 for estimating a communication quality level in the case of wirelessly communicating via the relay 3 installed at the first position with the master unit 1 at the second position on the basis of the acquired first radio wave intensity and second radio wave intensity; and a display control part 244 for allowing a display part 22 to display information based on the estimated communication quality level.SELECTED DRAWING: Figure 3 【課題】中継機の適した設置位置を容易に見つけることができるようにする。【解決手段】電波を発信する親機1と直接又は中継機3を介して無線通信可能な子機2は、第1位置において親機1から受信した電波の強度である第1電波強度と、第1位置において、第1位置よりも親機1から遠い第2位置に設置した中継機3から受信した電波の強度である第2電波強度とを取得する電波強度取得部241と、取得した第1電波強度及び第2電波強度に基づいて、第2位置において、第1位置に設置した中継機3を介して親機1と無線通信を行う場合の通信品質レベルを推定する推定部243と、推定された通信品質レベルに基づく情報を表示部22に表示させる表示制御部244と、を備える。【選択図】図3
