35X# Path
Change the audio path to A, where A =:
0 = Hands free (selects input signal AUDIO IN @ J3-pin 8
and outputs audio signal AUDIO OUT/ON-OFF @ J3-
pin 7; internal speaker and microphone are muted.)
1 = Speaker (normal audio path; selects internal mic and
outputs audio @ AUDIO OUT/ON-OFF @ J3-pin 7;
internal speaker is muted.)
2 = Alert (activates the alert transducer for as long as the
# key is pressed. To prevent overstressing the alert
transducer., DO NOT hold the # key down for
extended periods.)
3 = Handset (selects the internal mic and speaker.)
4 = Mute (all audio paths and supplies are off, DSP put to
sleep.) This command must be followed by a different
AUDIO-PATH command (not MUTE) in order to guar-antee
proper DSP functionality. Failure to do so may
result in a radio failure.
5 = Internal MIC Test (routes the internal mic audio
directly to AUDIO OUT/ON-OFF @ J3-pin 7, and
routes audio input at AUDIO IN @ J3-pin 8 directly to
the earpiece speaker.)
6 = External Handset (selects input audio at AUDIO IN @
J3-pin 8, and outputs audio at AUDIO OUT/ON-OFF
@ J3-pin 7; internal speaker and mic are muted, and
sidetone is turned on.)
7 = Reserved (not supported)
8 = Reserved (not supported)
9 = Boom MIC (selects input audio at AUDIO IN and
outputs audio at AUDIO OUT/ON-OFF to headset
connector; internal speaker and mic are muted, and
sidetone is turned on.)
This command enables all internal and external hardware
controls necessary to route audio to/from the correct
outputs/inputs.
