Test command

AT^SNFD=?

Response

Execute command

AT^SNFD

TA resets the parameters currently selected in audio modes 2 – 6 to their

factory values.

The restored values are: <inBbcGain>, <inCalibrate>, <outBbcGain>,

<outCalibrate[0 to 4]>, <sideTone>.

<outStep> is not be reset to its default. Instead, the current value will be

retained when the ME is powered down with AT^SMSO or restarted with

AT+CFUN=1,1.

Note

6.21 AT^SNFI Set microphone path parameters

Test command

AT^SNFI=?

Response

^SNFI: (list of supported <inBbcGain>s), (list of supported

<inCalibrate>s) OK

Parameters

See write command

Read command

AT^SNFI?

Response

^SNFI: < inBbcGain >, <inCalibrate> OK

Parameters

See write command

Write command

AT^SNFI=<inBbcGain>,

Response

TA sets microphone path amplifying.

Parameters

<inBbcGain> Setting for ADC gain Amplifier 0 - 7 (0=0dB, 7=42dB,

8 steps of 6 dB)

<inCalibrate> Multiplication factor 0 – 32767 for input samples

attenuation=20*log (inCalibrate/32767)

Reference

Note

· The read and write commands refer to the active audio mode.

· The write command works only in audio modes 2 to 6.

· The range of <inCalibrate> is up to 65535 but will be suppressed to

32767. Values above <inCalibrate> = 65535 will cause a failure.

· Changed values need to be stored with AT^SNFW for use after

restart.

· Attention! When you adjust the audio parameters avoid exceeding the

maximum allowed level. Bear in mind that exposure to excessive

levels of noise can cause physical damage to users!
