PURPOSE:To use efficiently a display section by using the display section for display of channel selecting position at the operation of channel selection in common use for display of a tuning voltage setting value at the operation of channel selection setting. CONSTITUTION:In designating, e.g., the channel 5 from a key switch input section 11 at the channel selection, the channel selecting position ''5'' is displayed on the display section 12, a tuning voltage setting data to select the channel 5 is read from a tuning data storage section 16, converted and outputted into a tuning control voltage by a D/A converting section 13. When a key input for tuning voltage change (e.g., tuning voltage increase key) is received from a key switch input section 11, a control section 18 changes the tuning voltage setting value data and outputs it from an output section 17. The control section 18 displays the change in the tuning voltage setting value data on the display section 12 in the length of band display. |
