17.17 AT^SNFV Set Loudspeaker Volume
Description: AT^SNFV can be used to set the volume of the loudspeaker to the value <outCalibrate>
addressed by <out-Step>. The read and write commands refer to the active audio mode.
The write command works only in audio modes 2 to 6.
Test Command Syntax: AT^SNFV=?
Response: ^SNFV: (list of supported <outStep>s)
OK
Read Command Syntax: AT^SNFV?
Response: ^SNFV: <outStep>
OK
Write Command Syntax: AT^SNFV=<outStep>
Response: OK
ERROR
+CME ERROR
Parameter Description:
<outStep>
The actual volume of each step is defined by the parameter <outCalibrate>, which can be set with AT^SNFO.
0...4 Default = 4.
Notes:
• Any change to <outStep> takes effect in audio modes 2 to 6. That is, when you change <outStep> and then
select another mode with AT^SNFS, the same step will be applied. Nevertheless, the actual volume can be
quite different, depending on the values of <outCalibrate> set in each mode. The only exception is audio mode
1 which is fixed to <outStep>=4.
• <outStep> is stored non-volatile when the ME is powered down with AT^SMSO or reset with AT+CFUN=1,1.
<outStep> is not stored by AT^SNFW.
• <outStep> can also be changed by AT^SNFO (Section 17.13) and AT+CLVL (Section 17.4).
17.18 AT^SNFW Write Audio Setting in Non-
Volatile Store
Description: AT^SNFW causes the TA to write the currently selected audio parameters to non-volatile
store. The saved audio profile includes the following parameters:
AT^SNFA: <atten>
AT^SNFI: <inBbcGain>, <inCalibrate>
AT^SNFO: <outBbcGain>, <outCalibrate>[0 to 4], <sideTone>
AT^SNFS: <audMode>
AT^SAIC: <io>, <mic>, <ep>.
