Tune

Press and hold the right end of the TUNE button to manually tune to the next higher frequency. Press and hold the left end of the TUNE button to manually tune to the next lower frequency. If you hold down the TUNE button in either direction for more than one second, the function goes to fast tune. On the AM band, the frequency advances in increments of 10 kHz in either direction. On the FM band, the frequency advances in increments of 0.2 MHz in either direction. In either case, when tune reaches the end of the band, the tune function will continue in the same direction at the opposite end of the band. Release the button when you reach the desired frequency. This dual function button is also used to set the clock.
