PURPOSE:To facilitate an operation, and to prevent an erroneous operation by constituting a device so that objected sound frequency and stereo mode can be set automatically when a satellite number and a channel number are selected. CONSTITUTION:When a stereo switching button 53 to a switch mode is selected, a mode switching circuit 33 is switched through a microcomputer 38, and objected sound signals are outputted to output terminals 34 and 35. At such a time, when a write button 54 on a keyboard 57 is depressed, the frequencies of display devices 55 and 56 perform flashing for a regulated time, and data, such as the satellite number, the channel number, the frequencies of channels A and B, the stereo mode, etc., are stored at a RAM50. After storing the data, that is, the completion of a preset, and when a control signal from an antenna positioner 7 is inputted to the microcomputer 38 through an input terminal 60, a preset objected frequency is displayed on the display devices 55 and 56, thereby representing that the data are stored without fail.
