With the look and feel of a simple PTT « Push To Talk » box, the Dual Push-to-Talk allows you to go beyond the radio limits of the APPI-Com :
By plugging in your audio device on one side, your APPI-Com and your Walkie-Talkie on the other, you will then hear both networks combined simultaneously!

Push To Talk will then allow you to choose which network you wish to speak in. A real gain in time, efficiency and security!
