It adopts DMR system with AI noise reduction, equipped with 512 channels and 16 zones, plus ARC4, AES128 & AES256 encryption for secure communication. Built with IP67 waterproof and dustproof rugged housing, it stably works at temperatures ranging from -30℃ to 60℃. It also retains classic practical designs including dual PTT buttons, VOX hands-free operation and long battery life. Additionally, the RB48D supports CPS software for preset message storage to recall it instantly on site. Ideal for high-rise construction sites and on-site team work, this digital walkie talkie delivers clear, anti-interference and reliable all-day onsite communication.

High Power

Boasting powerful 5W output, RB48D delivers strong signals and extensive coverage, keeping you seamlessly connected across sprawling large construction sites.

AI Noise Reduction

A professionally optimized noise reduction system effectively filters out various background noises such as machinery noise, impact sounds, and crowd chatter, while accurately extracting human voice. Even in loud and demanding environments, it helps deliver clearer audio and a more reliable communication experience.

Stable Digital Voice Quality

Compared with analog radios, DSP digital processing provides noise reduction, error correction, and clearer voice quality, ensuring more stable communication performance in complex environments.

Dual Mode Communication

The RB48D enables quick switching between DMR Digital and Analog working modes to meet diverse communication demands across various work sites without format limitations. DMR digital technology provides clearer voice quality, while analog mode maintains compatibility with existing radio systems.

IP67 Protection

IP67-rated waterproof and dustproof design provides protection against water immersion up to 1m for 30 minutes and dust particles, ensuring dependable operation in challenging industrial environments.

Rugged Material Design

PC and TPE housing combines strength, durability, and impact resistance, helping the radio withstand daily drops, bumps, and demanding job site conditions for reliable long-term use.

Wide Temperature Range

As Retevis's first industrial-grade digital two way radio, RB48D is designed for reliable performance in extreme conditions. It supports stable operation across a wide temperature range of -30℃ to 60℃, making it fully suitable for a variety of industrial work environments.

Long Battery Life

Powered by a 2000mAh large-capacity battery, it offers over 30 hours of standby time and at least 14 hours of continuous use, sustaining all-day uninterrupted communication on job sites.

Dual Slot Communication

With 16 zones, 512 channels, and storage for up to 128 contacts, the RB48D provides flexible communication management for large teams and multiple work groups, making it easier to organize and coordinate complex operations.

One-Touch Calling

Multiple calling modes including single call, group call, and all call enable fast communication with specific users, selected team members, or the entire team.

Advanced Communication Protection

ARC4, AES128, and AES256 encryption options provide multiple security levels for communication protection, helping safeguard important workplace communication and ensuring reliable data transmission for professional applications. For Motorola devices that adopt the same encryption mode, the RB48D can interoperate with them normally.

Charging Protection

The RB48D is compatible with both 5V/1A and 5V/2A charging specifications. Its built-in charging protection system with low voltage, overcurrent, overvoltage, and temperature protection helps prevent charging risks and ensures safe, reliable power management during daily operation.

Man Down Alert

Tailored for high-risk work scenarios, RB48D features a man-down alert system. It detects abnormal tilting via angle sensing and automatically triggers alarms to promptly alert teammates when workers fall down. It also supports multiple customizable alert methods such as private alert and voice alerts, providing enhanced safety protection during operations.

Easy Operation

Equipped with VOX hands-free voice activation and dual PTT buttons. You can talk without pressing keys, and trigger transmission conveniently from multiple angles amid busy onsite work.

Reliable Communication, Built for Demanding Worksites

As an industrial-grade DMR radio, RB48D combines digital clarity, rugged protection, wide channel capacity, long endurance and other practical features to deliver stable and secure communication for industrial operations, construction teams, and challenging work environments.
