Parameter Description

<outStep>(num)

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.
