Features of DH410 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
It 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 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 a 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.
