6) You can change the AM tuning scale to 9 kHz or 10 kHz.

After tuning in any AM station, turn off the receiver. While
holding down PRESET TUNING + or TUNING +, press
?/1. All preset stations will be erased when you change
the tuning scale. To reset the scale to 10 kHz (or 9 kHz),
repeat the procedure.
