PURPOSE: To easily and accurately adjust a receiving channel by storing a tuning voltage difference corresponding to the dispersion of a tuner in a data memory and correcting the tuning voltage impressed in accordance with the depression of a channel UP/DOWN key by the tuning voltage difference.

CONSTITUTION: When a channel setting switch 2 is set up to channel '4', a correction part 10c reads out the tuning voltage difference from the data memory 8. The channel UP/DOWN key 4 is depressed so as to receive the channel '4', and when the image of the channel '4' is received, the tuning voltage based upon the depression of the key 4 is corrected by the read tuning voltage difference and channel display data corresponding to the correction are outputted to an on-screen display 6.
