VOX Operation
The VOX system provides automatic transmit/receive
switching based on voice input to the microphone when
using the after- market Headset. With the VOX system
enabled, you do not need to press the
PTT
switch in or-
der to transmit.
Note
: The VOX system does not function when using just
the internal microphone; an external headset must be used.
Press and hold
the
[
6
(
DW
)] key for
3
seconds
to activate
the VOX system. The
“
” icon will ap-
pear on the display.
Without pressing the
PTT
switch, speak into
the microphone on the
Headset in a normal voice
level. When you start
speaking, the transmitter should be activated auto-
matically. When you finish speaking, the transceiver
should return to the receive mode (after a short delay).
To cancel VOX and return to
PTT
operation, press
and hold the [
6
(
DW
)] key for 3 seconds; the “
”
icon will disappear from the display.
The
FTA-230
provides for adjustment of the VOX Gain
via the Menu, to prevent accidental transmitter activa-
tion in a noisy environment. To set the VOX Gain:
Press the [
F
] key mo-
mentarily, then press
the [
(
SET
)] key
to activate the Menu
(“SET”) mode.
Rotate the
DIAL
selec-
tor knob to select Menu
Item “
VSNS
.”
Press the [
ENT
(
)] key
to enable adjustment of
this Menu item.
While speaking into the microphone on the Headset,
rotate the
DIAL
selector knob to the point where
the transmitter is quickly activated by your voice,
without causing background noise to activate the
transmitter.
When you have selected the optimum setting, press
the [
ENT
(
)] key to save the new setting, and
then press the
PTT
switch to exit to normal opera-
tion.
