1.10 Voice operated transmit (VOX)

In VOX mode the transceiver will react to your voice and transmit
automatically without you having to press the PTT button.
There is always a slight delay for the electronic switching, therefore starting
a transmission with an exaggerated length, throwaway, first word is
recommended e.g. "H-e-l-l-o Charlie One do you receive, over".
To enable the VOX feature press the "FCN" button three times.
VOX will flash on the LCD display. As default it is switched off.
To switch this feature on press either the UP or down button to scroll
through the levels. When the desired level is selected press the ENTER button
to confirm. Level 9 is the most sensitive setting and should be
used in low ambient noise environments. Level 1 is least sensitive
and should be used in a high ambient noise environment.
Once this feature is enabled in the menu you can turn it on and off by
pressing the VOX button located on the front panel. If you press and
hold this button you can change the levels.
Note : to get optimum performance from the VOX feature you should use a noise
cancelling headset or earpiece microphone (see accessory options marked VOX)
