Write command
AT^SNFS=
<audMode>
The write command serves to set the audio mode required for the connected
equipment. For use after restart of TC35i, you are advised to store the selected
mode to the audio profile set with AT^SNFW. Otherwise, audio mode 1 will be ac-
tive each time TC35i is powered up.
AT^SNFS can also be used in conjunction with AT^SAIC. This is useful, for exam-
ple, if both interfaces are operated alternatively to benefit from different devices.
Each audio mode can be assigned a specific interface. To do so, first select the
audio mode with AT^SNFS, then activate the audio interface with AT^SAIC and fi-
nally enter AT^SNFW to store the settings to your audio profile. To switch back
and forth it is sufficient to use AT^SNFS. See Chapters 7.5 for AT^SAIC and 7.33
for AT^SNFW.

OK
