Parameter Description:
Loudspeaker Volume Level
0...4 Default = 4
Notes:
• The write command can only be used in audio mode 2 - 6.
• The values of the volume steps are specified with the parameters [0],...[4] of the
AT^SNFO command.
• As an alternative to AT+CLVL, you can use AT^SNFO and AT^SNFV. The parameter is identical with
used by both commands.
• Any change to (or ) takes effect in audio modes 2 to 6. That is, when you change (or
) 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 =4 (or accordingly =4).
• (or ) is stored non-volatile when the ME is powered down with AT^SMSO or reset with
AT+CFUN=1,1.
17.5 AT+CMUT Mute Control
Description:
The AT+CMUT command mutes the microphone input. The command can be used in all
audio modes (1 to 6) and during a voice call only. See AT^SNFS for more details on the
various audio modes. As alternative, you can use the AT^SNFM command.
During an active call, users should be aware that when they switch back and forth
between different audio modes (for example handsfree on/off) the value of does
not change; i.e., the microphone mode is retained until explicitly changed.
