PURPOSE:To preset voice information data and store and display data in the order of frequency, by inputting a call sign with a voice. CONSTITUTION:When voice information data terminates, a data end pulse is outputted by an information existence detecting circuit. When receiving this data end pulse, a computer part 12 reads data of the highest frequency out of stored data and compares this data with frequency data, which is stored newly; and if the frequency of latter is lower, the former is transferred temporarily to a buffer area in the RAM 16, and memory area for the former and the latter are exchanged. This operation is continued until already stored frequency data to be compared is equal to or smaller than frequency data to be stored newly. Thus, data in the RAM 16 are rearranged in the order of frequency, and indicators 6a-6f of a memory indicator 6 correspond frequencies in order from the left to the right. |
