Features of DH400 DMR Portable Radio


  • Classic Design

    Dual-color body, lightweight, high-quality. Off-belt clip, classic knob layout, easy to operate.


  • Ruggedized Design

    18-pin waterproof accessory interfaces ensure IP65 protection.


  • Digital and Analog Compatibility

    This DMR digital radio supports digital and analog modes and provides rich services such as short messages, roaming, stun/revive, and radio check to help users work more efficiently.


  • Loud and Clear Voice

    2W high-power speaker, combined with an optimized sound cavity and MIC noise-reduction algorithm, makes loud and clear sound with maximum efficiency, ensuring clear communication in noisy environments.


  • Long Working Time

    With a standard 2500mAh battery and digital power-saving technology, the radio lasts for 18 hours in the analog mode and 25 hours in the digital mode (5:5:90 traffic model) and fully meets the continuous working requirements of the front-line users. 


  • Longer Communication Distance

    Carefully optimized RF circuit offers high receiving sensitivity of 0.16uV. Combined with an integrally formed helical antenna, it achieves longer-distance communication.


  • Safe and Reliable

    Lone worker and SOS alarm make user operation safe; basic voice encryption protects users' call information.
