The Voice Activated Transmit (VOX) feature enables you to use your radio "hands free." When VOX is turned on, the radio will automatically begin transmitting when you speak, without pressing the push-to-talk button. VOX works well for any application.
On most VOX-capable radios there is a slight delay between when you start speaking and when the microphone turns on so the first part of the conversation may be clipped. Most radio users overcome this by repeating the first word.
