Enables two talk paths on one frequency at the same time, improving communication efficiency and frequency utilization. Supports smooth communication during peak service hours.

Clear & loud digital voice

Digital Speech Error Correction Processing (AMBE+2™) delivers voice with good clarity and performance. Provides clearer voice quality than analog radios in most environments.

Emergency Alarm

Emergency alarm with high priority, which can send alerts to team members and control center in critical situations.

Digital-Analog Compatibility, better usability

Compatible with existing conventional analog radios and systems, enabling a smooth transition from analog to digital and improving equipment utilization.

VOX feature, hands-free operation

VOX voice-activated function allows voice-triggered calling with audio accessories, suitable for users who cannot operate the PTT button.

TFT HD Color Display, user-friendly operation

TFT color screen with intuitive icons and humanized menu, making information reading and control convenient.

High-capacity Li-polymer Battery

Equipped with a 2000mAh Li-polymer battery, supporting up to approx. 21 hours of operation to meet daily work needs.

Military-grade reliability

IP67 rated and compliant with MIL-STD-810 C/D/E/F/G. Tested for drop, temperature, humidity, dust and vibration. Maintains stable performance in daily commercial use even after accidental drops or splashes.

Voice Encryption for communication security

Built-in basic voice encryption function to help protect communication privacy.

Extended auxiliary services for richer experience

Optimized hardware supports functions such as remote monitor, remote detection, call alert, remote kill, remote revive, etc., for more flexible applications.

Advantage: AI-based Voice Recognition Technology

Built-in 36mm speaker and optimized AI voice recognition technology deliver louder and clearer audio by reducing ambient noise, lowering distortion and suppressing whistling from nearby devices. Users can communicate clearly in noisy environments.

Extended Communication Coverage

DR-105A adopts a high-sensitivity receiver and high-efficiency monopole antenna to improve signal penetration, ensuring stable calls in weak-signal indoor environments and maintaining good RF performance under low battery conditions.

The monopole antenna features a thickened thread design for better bending resistance and longer service life, helping increase radiation efficiency and communication coverage.

Bluetooth 5.0

DR-105A supports Bluetooth 5.0 with fast connection, wide compatibility, broad coverage and stable, low-latency calling.

Application

With ergonomic design, AI voice recognition, clear digital audio, and optional auto roaming, GPS, Bluetooth and digital trunking, DR-105A provides reliable communication support for emergency response and management dispatching in industries including commerce, manufacturing, railway, airport, hotel, shopping mall, security, entertainment venue and construction site.
