ABSTRACT:
When abbreviated numbers and telephone number are registered, these numbers are divided into several groups and group numbers are assigned to the groups, respectively. The group numbers are stored in a main memory area of a RAM. If a certain group number is input, a CPU displays all the abbreviated numbers corresponding to such a group number, but does not display the telephone numbers corresponding to the abbreviated numbers. When a call limitation is registered to a group number, a call with the abbreviated numbers to which such a group number is assigned is prohibited and these abbreviated numbers and telephone numbers corresponding to the abbreviated numbers are not displayed.
