  The 1.75-inch LCD screen and half-keyboard bring users a richer operating experience.

• 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 digital mobile 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 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 bring user operation safe; basic voice encryption protects users’ call information.

• Real-time Clock

  Built-in clock module, the time will not reset during battery replacement.
