PROBLEM TO BE SOLVED: To effectively release a mode for preventing the incoming call sound from being produced even when the mode for preventing the incoming call sound from being produced is set in a terminal such as a portable telephone. SOLUTION: An incoming call sound output in an incoming call sound output means 23 is limited in the case of an incoming call by the setting of a prescribed mode. When a previously registered special incoming call condition is detected in a state where the prescribed mode is set, the output limit of the incoming call sound is released.
