VOX Operation
If you want to have both hands free, use the (user-sup-
plied) Headset and activate the VOX (voice-actuated trans-
mit/receive switching) system.
Note
: The VOX system does not function when using just
the internal microphone; an external headset must be used.
To activate the VOX system using the Menu System:

] key, then press the
VOLUME
knob to
activate the Menu (“SET”) mode.
Rotate the
DIAL

Press the
VOLUME

Menu item.
Rotate the
DIAL
selector knob to select “

” (to en-
able the VOX system).
When you have made your selection, press the
VOL-
UME
knob to save the new setting, and then press the
PTT
switch to exit to normal operation.
Without pressing the
PTT
switch, speak into the mi-
crophone in a normal voice level. When you start
speaking, the transmitter should be activated automati-
cally. When you finish speaking, the transceiver should
return to the receive mode (after a short delay).
To cancel VOX and return to
PTT
operation, just repeat
the above procedures, selecting “
oFF

When the VOX system is activated,
the “

display.
