In a mobile terminal having an automatic startup mode of a television signal receiving function using a timer, startup is properly controlled in consideration of remaining battery capacity to thereby prevent an occurrence of unexpected lack of battery capacity. In a state where an alarm mode using a television broadcast or an FM broadcast has been set, a control unit makes low voltage determination of a battery at a time point when a time has been up. When an output voltage value of the battery is lower than a threshold, the control unit outputs an alarm sound from a speaker instead of starting up a TV receiver and causes a display to display a low voltage message.
