Chapter 16 – Audio Commands

Multi-Tech Systems, Inc. AT Commands for EDGE (E1) Modems (S000474A) 265

at^snfi=5,45

at^snfa?

^SNFA: 45

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.
