18.17 AT^SNFV Set loudspeaker volume
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.
Syntax
Parameter Description
The actual volume of each step is defined by the parameter <outCalibrate>, which can be set with AT^SNFO.
0...4(P)
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 18.13) and AT+CLVL (Section 18.4).
• Users should be aware that when using this AT command quickly after "^SYSSTART" a "+CME ERROR:
operation temporary not allowed" is received. The audio data may not yet be accessible, resulting in a short
delay (less than 400ms) before the requested AT command response is returned.
