<p>When the folding case of a mobile terminal is folded, a time counting is started. Upon a receipt, it is determined whether the time counting is in progress. If so, the counted time is acquired and it is determined whether the acquired counted time is shorter than a predetermined time. Otherwise, the operational statuses of a display part (4) and a backlight (5) are acquired and it is determined whether they are coincident with operational statuses registered in advance. When the acquired counted time is shorter than the predetermined time or when the operational statuses of the display part (4) and backlight (5) are coincident with the registered operational statuses, a first sound level is used to output a receipt tone. When the acquired counted time is equal to or longer than the predetermined time or when the operational statuses of the display part (4) and backlight (5) are not coincident with the registered operational statuses, a second sound level is used to output the receipt tone.</p> |
