Notes

• The AT^SAIC Write command is usable only in audio modes 2 - 6. If AT^SNFS=1, any attempt to u se 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.
