We have turned it on,then we need to improve the sensitivity of sound control. The sensitivity of VOX needs to be set according to the external environment. If you are in a noisy environment, such as a restaurant or  construction site.  You can improve the sensitivity to 6~10 .But when you are in a silent environment ,just set it to 1~5.

After that ,When we talk again, we don’t have to press the PPT button. Just speak louder then the voice has been transmitted. I changed the sensitivity to 6,so  my voice has to be a little bit louder to signal.If you change it to 10, just a tiny voice can be sent.but it might make noise.

And if you don’t need this function.Just setting in the software and  find the menu items ,Cancel the tick.


This feature benefits many working people with both hands.I think it is useful .If you still don’t know how to use RT3  VOX function, please contact us by email, vip@retevis.com, please feel free to leave message here!
