The new generation of DH4 series digital radios, packing versatile features into compact bodies, helps business users to improve work efficiency at a lower cost.
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.
