17.4 AT+CLVL Loudspeaker volume level
Syntax
Parameter Description
Loudspeaker Volume Level
0...4
(D)
Notes
• 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],...<outCali-
brate>[4] of the AT^SNFO command.
• As an alternative to AT+CLVL, you can use AT^SNFO and AT^SNFV. 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 accordingly <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.
