        \nautomatically roam among all sites and stay connected, delivering more flexibility and efficiency.<\/p>\n

          \n
        • \n

          Excellent Audio Quality<\/h4>\n<\/li>\n<\/ul>\n

          Excellent digital audio quality comes from the AMBE + 2 vocoder and FEC technology<\/p>\n

            \n
          • \n

            Scan\/ Monitor<\/h4>\n<\/li>\n<\/ul>\n

            At a convenient push of a button, you can monitor all the conversations on your channel, or you can scan\u00a0conversations on different channels.<\/p>\n

              \n
            • \n

              Radio Priority-Based Interruption<\/h4>\n<\/li>\n<\/ul>\n

              A radio with higher priority can interrupt communications between radios with lower priorities, either to transmit or to clear a channel for more important communications. This brings better dispatching efficiency to the team.<\/p><\/div>\n<\/div>\n
