Notes:
Tone/VOL mode has four selections:
Bass/treble mode: no digital volume control, fixed volume level at 59
Digital volume mode: no bass/treble effect, volume levels from 0 to 63
Mixed mode 1: bass/treble and digital volume coexist, volume levels from 0 to 63, scale to 0~59
Mixed mode 2: bass/treble and digital volume coexist, volume levels from 0 to 63
The Tuning preference of FM has two selections:
Preference1: When tuning to adjacent channels, the volume level decreases by 2 dB
Preference2: When tuning to adjacent channels, the volume level remains unchanged
The Tuning preference of SW has two selections:
Preference1: When tuning to adjacent channels, the volume level decreases by 2 dB
Preference2: When tuning to adjacent channels, the volume level remains unchanged
There is no tuning preference selection for AM mode.
