ABSTRACT:
Incoming call tones and program numbers as numbers used to specify respective incoming call tones are stored in a memory of a cellular phone so as to be set in correspondence to each other. The program numbers are used to specify corresponding incoming call tone melodies, data of which is stored in the memory. A control circuit of the cellular phone, whenever an incoming call is received, increments a value of a counter indicating the corresponding program number by one, and uses an incoming call tone corresponding to the program number corresponding to the value of the counter.
