You can change the AM tuning interval to9 kHz. After tuning in
any AM tuning in any AM station, turn off the power of receiver
once. While holding down the TUNING + button, press the
POWER switch. When you change the interval, all the preset
stations will be eraséd. To reset the interval, repeat the same
procedure. (US, Canadian model)
