Si4840/44-DEMO
Notes:
Tone/VOL mode has 4 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 mode has 4 selections:
?
?
?
?
Preference 1: When tuning to adjacent channels, allow stereo separation and stereo indicator is on, volume
level decreases by 2 dB.
Preference 2: When tuning to adjacent channels, allow stereo separation and stereo indicator is on, volume
level is unchanged.
Preference 3: When tuning to adjacent channels, disable stereo separation and stereo indicator is off, volume
level decreases by 2 dB.
Preference 4: When tuning to adjacent channels, disable stereo separation and stereo indicator is off, volume
level is unchanged.
The tuning preference of SW mode has 2 selections:
?
?
Preference 1: When tuning to adjacent channels, the volume level decreases by 2 dB.
Preference 2: When tuning to adjacent channels, the volume level remains unchanged.
There is no tuning preference selection for AM mode.
