Abstract

PURPOSE:To ensure a simple confirmation of several reception frequencies, by writing the signals to be displayed via a decoder into another memory when the reception frequency data is written into a memory. CONSTITUTION:When several reception frequency data are written into the memory 8, the several frequency dot display signals obtained by converting the preset reception frequency data by a decoder are written simultaneously into the memory 18. Then only the frequency dot display signals corresponding to the present reception frequency data are supplied to the dot display device 14 via the OR circuit 19 when the signal reading switch 20 is off. When the switch 20 is turned on, the plural preset reception frequency data are read out of the memory 18 and then displayed on the device 14 along with the present frequency data and via the OR circuit 19.
