Abstract

PURPOSE:To make the stop key needless, by releasing the scan or the seek mode when the corresponding scan key or seek key is depressed again in the course of scan or seek operations. CONSTITUTION:The scan key and the seek key of keyboard 10 are depressed to set the mode. When one key of channels of keyboard 10 is depressed, the scan or seek mode is stopped, and simultaneously, the frequency preset according to the depressed channel is read out from a memory to make to make it possible to receive the frequency. When the reset key is depressed, the scan or seek mode is stopped to set the reset mode. If FM and AM bands are switched, the scan or seek mode is stopped to perform band switching. When said keys are not operated at all, scan or seek operations continue.
