グ回路。 In an auto-tuning circuit that automatically selects a reception radio wave by moving the tuning frequency by operating a tuning key, there is a means for measuring the continuous operation time of the tuning key, and a key operation time measured by this means in advance. An auto-tuning circuit comprising means for outputting a tuning start signal when a set time has elapsed, and a tuning control circuit for starting a tuning operation based on the signal output from the means.
