Overview

Push-to-talk allows you to call the tracking device and talk to the driver directly. No specific installation is needed – plug the 3.5 mm connector into the audio jack and you are good to go. Communication is half duplex (one way). When the button is released, the driver can hear the caller, when the button is pressed, the driver can talk.
