> 18.10 | AT^SNFD Set audio parameters to manufacturer default values

> AT^SNFD sets the active audio parameters to manufacturer defined default values. These default values can be changed and stored by the user and also by download with a new set of parameters.
> The restored values are:
> AT^SNFA: <atten>
> AT^SNFI: <inBbcGain>, <inCalibrate>
> AT^SNFO: <outBbcGain>, <outCalibrate>[0 to 4], <sideTone>
> AT^SAIC: <io>, <mic>, <ep>
> AT^SNFS: <audMode>

> Note

> • | Remember that the factory set audio mode 1 is fixed to <outStep>=4. Consequently, AT^SNFD restores <audMode> together with <outStep>=4, but does not affect the values of <outStep> currently selected in audio modes 2 - 6. This means, if <audMode>=1, the read commands AT^SNFO, AT^SNFV and AT+CLVL will always deliver <outStep>=4. In all other modes the <outStep> value is retained until explicitly changed.
