tively.

Default: 3.2/3.2/5.9/7.0/7.0/9.0/9.5/10.0 MHz for
wideband SW1 to SW8 respectively.
De-emphasis: 50 or 75 µs
Default: 75 µs
Channel space: 9 or 10 kHz
Default: 9 kHz
Tone/VOL mode: a-d
Default: d
Tuning preference: a-b
Default: a
Tuning preference: a-b
Default: a
Notes:
1. Tone/VOL mode has four modes:
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 & digital volume coexist, volume levels from 0 to 63, scale to 0 ~59
Mixed mode 2: bass/treble & digital volume coexist, volume levels from 0 to 63
2. The Tuning preference of FM mode and SW mode has two preferences:
preference1: When tuning to adjacent channels, the volume level decreases by 2 dB.
preference2: When tuning to adjacent channels, the volume level remains unchanged.
3. There is no tuning preference selection for AM mode.
