PROBLEM TO BE SOLVED: To provide a mobile phone wherein a function set in mistake can easily be restored to an original setting. SOLUTION: A control section 30 discriminates whether or not a frequency of use of a prescribed function exceeds a prescribed frequency of use on the basis of a setting revision request received by an input section 1. When the frequency of use of the prescribed function does not exceed the prescribed frequency of use, a recording section 2 records before-revision setting information. COPYRIGHT: (C)2007,JPO&INPIT
