6.22 AT^SNFO Set audio output (= loudspeaker path) parameter
Test command
AT^SNFO=?

e>
Set TA´s loudspeaker path parameters.
Response
<outBbcGain> <outCalibrate[0]>...<outCalibrate[4]> <(outStep)> <sideTone> OK
Parameters
<outBbcGain> Setting for DAC gain Amplifier attenuation 0 – 3 (0=0 dB, 3=-18
dB, 4 steps of 6 dB)
<outCalibrate[0]> ... <outCalibrate[4]>
Multiplication factor 0 – 32767 for output samples
Attenuation = 20 * log (outCalibrate[n]/32767)
<outStep> Setting of actual volume; 0 – 4
<sideTone> Multiplication factor 0 – 32767 determining how much of the
original microphone signal is added to the earpiece signal.
Side Tone Gain/dB = 20 * log (sideTone/32767)
Reference
Siemens
Note
1. Write command works only in audio modes 2 to 6!
2. Read and write options of this command refer to the active audio mode.
3. The values <outStep> can be changed also by ^SNFV .
4. The range of <outCalibrate> is up to 65535 but will be suppresed to 32767.
A value above <outCalibrate> = 65535 will cause a error
5. Changed values will not be stored automatically, but via the at command
AT^SNFW except <outStep>. The parameter <outStep> will be saved after
AT^SMSO only.
6. The volume level as well as mute affects all audio modes.
7. In case of audio mode 1 the parameter <outStep> has no effect.
8. Attention! In case of changing audio Parameters it is possible that the
maximum allowed volume will be exceeded and users could get damage
to their hearing!
