Parameter
<level> Loudspeaker Volume Level (0-4)
Reference
GSM 07.07
Note
· The write command can only be used in audio mode 2 – 6.
· The values of the volume steps are specified with the parameters
<outCalibrate[0]>,...<outCalibrate[4]> of the AT^SNFO command (see
Chapter 8.24).
· As an alternative to AT+CLVL, you can use AT^SNFO and AT^SNFV
(Chapter 8.27). The parameter <level> is identical with <outStep>
used by both commands.
· Any change to <level> (or <outStep>) takes effect in audio modes 2 to
6. That is, when you change <level> (or <outStep>) and then select
another mode with AT^SNFS, the same step will be applied.
The only exception is audio mode 1 which is fixed to <level>=4 (or ac-
cordingly <outStep>=4).
· <level> (or <outStep> is stored non-volatile when the ME is powered
down with AT^SMSO or reset with AT+CFUN=1,1.
