Parameter Description

[1] Audio mode 1: Standard mode optimized for the reference handset, that can

be connected to the analog interface 1 (see your "Hardware Interface Descrip-

tion" for information on this handset.) To adjust the volume use the knob of th e

reference handset. In audio mode 4, this handset can be used with user

defined parameters.

Note: The default parameters are determined for type approval and are not

adjustable with AT commands.

AT^SNFD restores <audMode> 1.

2 Audio mode 2: Customer specific mode for a basic handsfree device (Siemens

Car Kit Portable).

Analog interface 2 is assumed as default.

3 Audio mode 3: Customer specific mode for a mono-headset.

Analog interface 2 is assumed as default.

4 Audio mode 4: Customer specific mode for a user handset.

Analog interface 1 is assumed as default.

5 Audio mode 5: Customer specific mode.

Analog interface 1 is assumed as default.

6 Audio mode 6: Customer specific mode.

Analog interface 2 is assumed as default.

Notes

• The write command can be used during a voice call to switch back and forth between different modes. This

allows the user, for example, to switch handsfree operation on and off.

• Users should be aware that <outStep> is a global setting. This means, when another au dio mode is selected

during a call, the value of <outStep> does not change. This is also true for mute operation which can be set

with AT^SNFM or AT+CMUT: If the microphone is muted and the user selects another audio mode durin g the

call, then the microphone remains muted until explicitly changed . Exception: In audio mode 1 <outStep>=4

is fix.
