PROFESSIONAL DIGITAL TWO-WAY RADIO
SMS
GPS(Optional)
Voice Encryption
Digital / Analogue mode switchable
Features: On a permiteed frequency, DMR radio can obtain double calling capacities by means of TDMA technology. Supporting both analogue and digital working modes, and realizing a stable switch between both modes. Prolonging battery life. Compared with analogue radio, the battery life between two charging cycles for TDMA digital radio is much better, max up to 40%. Integrated voice and data, not only improve the work efficiency, but also support multiple applications. Able to define side keys to facilitate users to do some common functions. Providing TFT color display and visual icons, and user-friendly menu operation. To use digital vocoder AMBE+2™ to ensure excellent audio quality. Whatever in kinds of environment, it could provide clearer sound quality than analogue radio. To use TFT high definition display makes operation easier and agiler.
