PROBLEM TO BE SOLVED: To easily locate a position of a radio terminal attached to a management target regardless of a state of a battery of the radio terminal.SOLUTION: A radio terminal which can acquire position information, comprises: a generation unit which receives a radio wave emitted from an external device to generate electric power; a detection unit which detects the generated power being equal to or more than a threshold; a first acquisition unit which acquires a state of a built-in battery; and a control unit which, when the detection unit detects the generated power being equal to or more than the threshold, displays the state of the battery on a display unit by using the generated power. |
