A broadcast receiver with an electronic tuning circuit (7), a detector circuit (4, 5) for detecting a particular signal from the received signals and with an indicating circuit (10, 11, 12, 13) for indicating the presence or lack of the particular signal via an output signal of the detector circuit (4, 5). An automatic scanning control circuit (8, 9, 18) is constructed in such a manner that the electronic tuning circuit (7) can carry out a scan when the particular signal is not detected, by the output signal of the detector circuit (4, 5) being applied to a scanning control connection (17) of the electronic tuning circuit (7). <IMAGE> |
