Next push one of the pushbuttons all the way in as far as it will go and hold it there. Now tune in the station you want with the tuning knob Tune back and forth until the station is clear and distinct, then release the button. Continue setting each push button in the same way. Now rotate the tuning knob to the right (clockwise) as far as it will turn.
