Claims

[Claims for Utility Model Registration] (1) A receiving circuit that can change the receiving frequency, a memory that stores signals representing a plurality of receiving frequencies, and a receiving electric field strength of the signal received by the receiving circuit. level discrimination means for level discriminating at a predetermined discrimination level; output means for converting the signal from the receiving circuit into sound or displaying an image; and based on the signal stored in the memory, the receiving circuit at the receiving frequency is operated to receive, the output means outputs, and while the output means is at rest, the signals stored in the memory are sequentially read out, and the received electric field strength is set to the discrimination level of the level discrimination means. or more, the contents of the memory are left as they are, and when the received electric field strength is less than the discrimination level, the reception frequency is changed to a reception frequency other than the reception frequency represented by the signal stored in the memory, and 1. A preset receiver comprising control means for transmitting and re-storing a signal representing a reception frequency whose reception electric field strength is equal to or higher than the discrimination level. (2) The control means determines whether, during the operation of sequentially changing the reception frequency, a reception frequency having a reception field strength equal to or higher than the discrimination level exists at a reception frequency other than the reception frequency represented by the signal predetermined and stored in the memory. 2. A preset receiver according to claim 1, wherein the preset receiver retains the contents of said memory when not being used.
