* You can change the AM tuning interval between 9 kHz and 10kHz. After tuning in any AM station, turn off the receiver. Hold down the PRESET TUNING + button and press the 1/u (power) button. All preset stations will be erased when you change the interval. To reset the interval, repeat the procedure. (US model) General System
