Based on DMR standards, the new generation of digital radio BP660 brings innovations and enhancements in appearance, structure, and performance. It integrates intelligent noise reduction, optimal reception, flexible dispatch, and simple operation, delivering clear audio, wider coverage, fast respond, precise positioning, and enhanced protection, bringing exceptional communication experience.

AI Noise Reduction
BP660 comes with an in-built high-power speaker and AI noise reduction technology, enabling 360°sound pickup, effectively filtering background noise, and delivering clear audio anytime, anywhere. Incorporates automatic acoustic feedback suppression to suppress short-distance howling, monitor and block feedback loop in real-time, and provide seamless voice experience in crowded areas, significantly enhancing voice communication.

Enhanced Anti-Interference
BP660 employs a customized shielding case on its main board that isolates interference signals while preventing internal signals from radiating outward and enhancing signal stability. In scenarios such as signal edge areas, wide-range, and long-distance communication, the BP660 optimizes RF performance by reducing front-end link loss and enhancing back-end demodulation capability, improving reception sensitivity, and expanding communication coverage.

Multiple Alarms
BP660 supports multiple alarm modes including one-key alarm, lone worker, and man down to inform dispatch console immediately in emergencies and provide reliable security assurance.

Voice Encryption
BP660 incorporates dynamic, static, AES256, and ARC4 encryption to secure communications and effectively avoid information leakage lead by eavesdropping or interference.

Precise Positioning
BP660 allows location and distance display when both parties enabled satellite positioning, providing accurate orientation and distance information. It incorporates optional satellite positioning for real-time tracking and managing static and moving status, effectively coordinating and managing operational personnel, and improving command and dispatching efficiency.

DMR Narrowband Communication
The BP660 DMR radio delivers excellent communication performance, providing better voice and audio quality in a wider signal range. It enhances system application management for digital communications, allows it to access BelFone SDC and SVT system and carry out command and dispatch, intelligent management, and dynamic channel allocation.

Rich Applications
BP660 supports an optional Bluetooth 5.0 modular that allows to access wireless audio device, wireless PTT device, offering extensible interface options. Besides that, it also allows an optional 250 hours recording to sustain long time communication.

Excellent Design
The 1.77-inch screen comes with the user-friendly interface, brings more intuitive information display and provides convenience for simple operation. Rated IP68 protection, this radio is rugged and durable with great impact resistant and enhanced anti-oxidation capacity to endure various harsh environments.
