Bringing you a whole new set of digital features, such as two timeslots, versatile calls, remote kill\/revive, and a clear digital audio, this is a cost-effective radio solution for shop fronts, small warehouses, schools, hospitality, pubs and clubs, restaurants and bars, car park attendants and much more.<\/h4>\n
\n

Highlights<\/h4>\n
\n
    \n
  • \n

    Small Size and Lightweight<\/h4>\n<\/li>\n<\/ul>\n

    Small enough to be held comfortably in your hand and light enough not to be a burden.<\/p>\n

      \n
    • \n

      IP54 Dust & Water Protection<\/h4>\n<\/li>\n<\/ul>\n

      With lP54 protection, this smart and compact radio is built to last and to challenge all kinds of tough communication environments.<\/p>\n

        \n
      • \n

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

        This function enables a radio with higher level to interrupt communications between radios with lower levels, giving higher priority to radios with higher levels. This means better dispatching efficiency.<\/p>\n

          \n
        • \n

          A Long Battery<\/h4>\n<\/li>\n<\/ul>\n

          BF-TD446 can function for longer than any conventional analog radios. Battery life is one less thing to worry about!<\/p>\n

            \n
          • \n

            Scan Monitor (programmable)<\/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 conversations on different channels.<\/p>\n

              \n
            • \n

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

              Excellent digital audio quality comes from the AMBE+2TM\u00a0<\/sup>vocoder and FEC technology<\/p>\n

                \n
              • \n

                Private Call, Group Call and All Call<\/h4>\n<\/li>\n<\/ul>\n

                The versatile calling functions bring more efficiency to your teamwork.<\/p>\n

                  \n
                • \n

                  Transmit interrupt<\/h4>\n<\/li>\n<\/ul>\n

                  This function enables a supervisor to interrupt a radio conversation in order to clear a channel for more important communications.<\/p>\n

                    \n
                  • \n

                    DMO Pseudo Trunk<\/h4>\n<\/li>\n<\/ul>\n

                    The user can choose slot 1 or slot 2 for communications. When one slot is occupied, the radio will automatically switch into the free slot. Frequency efficiency is greatly increased.<\/p>\n

                      \n
                    • \n

                      DMO True 2-Slot<\/h4>\n<\/li>\n<\/ul>\n

                      In direct mode, this radio supports two voice calls simultaneously due to DMR two timeslots, which means two communication paths at 1 frequency with no extra costs or frequency license.<\/p>\n

                        \n
                      • \n

                        Digital\/Analog Dual Modes<\/h4>\n<\/li>\n<\/ul>\n

                        Receive both analog and digital signals on a single channel and can automatically switch into the needed mode for efficient communications.<\/p><\/div>\n<\/div>\n
