VOX is the function to transmit audio just by speaking into a microphone without pressing the PTT
switch.
This function can be used when a user cannot press the PTT switch, for instance, when a user is using both hands for other
tasks.
VOX is the function that can be used only when a user wears the headset and when the transceiver is operated in a
Conventional system (Analog, NXDN, P25).
To use VOX, a headset needs to be connected to the transceiver.
Portable:
For Portable, KHS-14, KHS-15 (Headset), or a headset which supports Bluetooth (Headset Profile) needs to be connected
to the transceiver. The following are the behaviors of each device by the connection status.
