Abstract

PURPOSE: To enable the channel selection with the designation of channel number only, by providing the key data area, channel number and the channel selection voltage corresponding to it with the non-volatile memory.

At channel selection, when the channel selection button 9 of the key board switch 8 is depressed, the address Aa of the area 3, for example, is addressed. The data Ab is read out and the address of the designated channel is displayed 13. Further, the address Ba of the area 4 corresponding to the address Aa is addressed and the data Bb is read out and converted 6 into analog value and fed to the electronic tuner 7, to receive the designated channel.
