Abstract
PURPOSE: To enable the preset again even with the relation between the memory content and the reception frequency of tuner not matched, by providing the selection means which can be changed for the write-in enable non-volatile memory and the memory content at the electronic tuner channel selection unit.
CONSTITUTION: The channel number of the fine tuning data are preset to an arbitrary part of the non-volatile memory 9 with the preset selection button 2 of the channel selection preset panel 1. When the digital value stored in the memory 9 and the reception frequency are not matched, the selector switches 6 and 7 are selected with the selection button 2 and the digital voltage corresponding to the specified channel is controlled with the microcomputer 3 by operating the up-down button for preset of panel 1, and the matched value is stored to the memory 9. Thus, even if the digital code stored in the memory 9 is changed over the drawing in range of the automatic frequency control circuit due to some causes, the preset of digital value in agreement with the channel selection frequency to the memory 9 is made possible again.
