Parameter Description:
<audMode>
1 Audio mode 1: Standard mode optimized for the reference handset that can be connected to the
analog interface 1. To adjust the volume use the knob of the reference handset. In audio mode 4,
this handset can be used with user defined parameters.
This is the default if no value is entered.
Note:
commands.
AT^SNFD restores <audMode> 1.
2 Audio mode 2: Customer specific mode for a basic handsfree (speakerphone) device.
3 Audio mode 3: Customer specific mode for a mono-headset.
4 Audio mode 4: Customer specific mode for a user handset.
5 Audio mode 5: Customer specific mode.
6 Audio mode 6: Customer specific mode.
Notes:
• The write command can be used during a voice call to switch back and forth between different modes. This
allows the user, for example, to switch handsfree operation (speakerphone) on and off.
•
<outStep> is a global setting. This means that when another audio mode is selected during a call, the value of
<outStep> does not change. This is also true for mute operation, which can be set with AT^SNFM or
AT+CMUT: If the microphone is muted and the user selects another audio mode during the call, then the
microphone remains muted until explicitly changed. Exception: In audio mode 1 <outStep>=4 is fix.
• For use after restart of the module, you are advised to store the selected mode to the audio profile saved with
AT^SNFW. Otherwise, audio mode 1 will be active each time the module is powered up.

The write command serves to set the audio mode required for the connected equipment.
AT^SNFS is used with AT^SAIC. Each audio mode needs to be assigned to interface 1
via the AT^SAIC command. To do so, first select the audio mode with AT^SNFS, and then
activate the audio interface with AT^SAIC and, finally, enter AT^SNFW to store the
settings to your audio profile. To switch back and forth it is sufficient to use AT^SNFS.
Any changes made with this command will also require you to send the
