摘要

A mobile device (1) is provided with: a communication part (11) for communicating through wireless communication; a display part (12); and a display controller (131) for control in order to display, on the display part (12), a settings input screen for inputting settings for a household electrical device (3). Prior to display of the settings input screen by the display controller (131), the communication part (11) transmits a request signal to check whether anyone is present in the surrounding area of the household electrical device (3), and in the event that no one is present in the surrounding area of the household electrical device (3), the display controller (131) displays on the display part (12) a settings input disabled screen indicating that household electrical device (3) settings will not be accepted, without displaying the settings input screen on the display part (12).
