Abstract: A mobile phone includes a condition storage unit storing therein a condition related to periodically-scheduled events that involve ringing of a device. In addition, the mobile phone includes a judging unit that judges whether an input operation input via an input unit of the device matches the condition stored in the condition storage unit. The mobile phone also includes a skip processing unit that, when the judging unit determines that the input operation matches the condition, inhibits the ringing scheduled at a nearest ringing time from being performed, calculates a ringing time that arrives following the nearest ringing time according to a periodical schedule, and configures a setting so as to enable the ringing scheduled at the calculated ringing time.
