TRANSMIT FUNCTIONS 9

Note:
◆ If the audio source with Data VOX disabled is selected if the
transceiver is left connecting to a PC, the transceiver may
occasionally be placed in transmit state by the signal from the
audio source.
◆ If you leave the transceiver connected to the audio source, you
must disable the audio source for Data VOX.
◆ If "DATA VOX" is assigned to a PF key, the audio source can be
changed with a press of the key. {page 16-6}
ADJUSTING THE VOX GAIN
VOX Gain for the VOX function (Voice) allows you to adjust
the VOX Gain following the volume of audio sourced from
the MIC connector and the ambient noise conditions.
Data VOX for the data allows you to adjust the VOX Gain
of the data sourced from the ANI terminal of the ACC 2
connector and from the (USB-A and USB-B) and
OPTICAL IN connectors on the rear panel.
■ VOX Function (Voice)
VOX will operate correctly if you adjust the VOX gain level
so that the audio from the MIC but not the ambient noise
level keys the transmitter.
1 Speak into a microphone and rotate the [VOX GAIN]
control to adjust the VOX gain.
You can adjust the VOX gain enabling the transceiver to
reliably transmit each time you speak into the microphone.
Rotate the VOX GAIN control clockwise to increase the
sensitivity level, allowing VOX to recognize even a soft-spoken
voice. The VOX function may occasionally be activated by
background noise.
Note:
◆ Pressing and holding [VOX/SEL] also opens the VOX screen. You
can adjust the VOX gain level of a signal input from the MIC jack in
the range of “0” to “255”.
◆ In this configuration, you can adjust the VOX level for the audio
sourced from the MIC jack. Even if the audio source is selected
for Data VOX in the Modulation Source screen, the parameter
configured for VOX Gain cannot be applied.
■ Data VOX
1 Press and hold [DATA/SEL] to open the VOX screen.
In the VOX screen, a line highlights the selected audio
source, and a row highlights the selected configuration item.
2 Press [ ] (F2) or [ ] (F3) to select the
row for the audio source.
You can select from “ACC 2”, “USB” and “Optical” row for the
audio line to be adjusted.
3 Press [ ] (F4) or [ ] (F5) to select the line
for “VOX GAIN”.
4 Press [-] (F6) or [+] (F7), or rotate the MULTI/CH
control to adjust the VOX level.
• Applying the audio signal from the modulation source
selected in step 2, you can select the VOX level to allow the
transceiver to transmit by receiving an audio signal.
• Available range is “0” to “20” (in steps of 1). The default is
“10”.
5 Press [ESC], or press and hold [VOX/SEL] to exit.
ADJUSTING THE VOX DELAY TIME
There may be times when the transceiver reverts to
the receive state during transmission of audio signal
and data with the VOX function or when the end of
your conversation or data is interrupted and cannot be
transmitted. To avoid such problems, reserve the delay
time so that the transceiver does not immediately revert to
the receive state.
