Notes

• The

AT^SAIC

Write command is usable only in audio modes 2 - 6. If

AT^SNFS

=1, any attempt to use the

AT^SAIC

Write command returns "+CME ERROR: operation not allowed". This is because all default param-

eters in audio mode 1 are determined for type approval and are not adjustable.

• To allocate a specific audio mode to one of the audio interfaces, first select the audio mode with

AT^SNFS

and then choose the interface using

AT^SAIC

.

• The factory defaults of

AT^SAIC

vary with the selected audio mode.

If

AT^SNFS

=1 or 4 or 5, then

AT^SAIC

=2,1,1.

If

AT^SNFS

=2 or 3 or 6, then

AT^SAIC

=2,2,2.

AT^SNFD

can be used to reset the factory defaults.

• For use after restart of the ME, you are advised to store the settings of

AT^SAIC

and

AT^SNFS

to the audio

profile set with

AT^SNFW

. Otherwise, audio mode 1 (

AT^SNFS

=1) and audio interface 2 (

AT^SAIC

=2,1,1) will

be active each time the ME is powered up.
