Notes:
• This command is provided for compatibility with former products and is a subset of AT^SNFI. The parameter
<inCalibrate> of AT^SNFI is identical with <atten> of AT^SNFA.
• To make the changes persistent use AT^SNFW.
• This command is not PIN protected.
• This command is supported in airplane mode.
16.10 AT^SNFD Set Audio Parameters to Manufacturer
Default Values
Description: 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>
Syntax: Test Command: AT^SNFD=?
Response: OK
Exec Command: AT^SNFD
Response: OK
ERROR
+CME ERROR: <err>
Notes:
• 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.
• This command is not PIN protected.
• This command is supported in airplane mode.
