Select differential earpiece amplifier

3 Selects both amplifiers. Note that both amplifiers are connected in parallel and
therefore, get the same output power if
<ep>=3.
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. (Although given by default, this setting applies to the TC35i
module only, it cannot be used with the TC35i Terminal where the second audio interface is not connected.
Nevertheless, you can configure TC35i Terminal for operation with audio modes 2, 3 or 6 by setting
AT^SAIC=2,1,1 instead. See examples provided with AT^SNFS.)
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.
