Abstract
A large number of name and telephone number numerical data can be stored in a RAM, and a reservation flag which represents whether a call is made or not can be set for each telephone number numerical data. A time mode for displaying time, a search mode for sequentially displaying all telephone number data stored in the RAM, or a reservation mode for displaying only the telephone number data having a reservation flag can be selectively set upon operations of switches SW1 and SW3. A dialing tones generator and a speaker are arranged to convert the displayed telephone number data into dialing tones and output the converted dialing tones.
