Key Features

Slim and Efficient Design

The PR900 features a compact 1U, 19-inch rack-mount design, perfect for space-constrained environments like control rooms or mobile setups. Its integrated power supply with battery backup ensures uninterrupted operation, even during power outages. The 2.0-inch HD color LCD display simplifies configuration and real-time monitoring.

Advanced DMR Performance

Utilizing DMR Tier II two-slot TDMA technology, the PR900 supports two simultaneous voice or data calls within a 12.5 kHz bandwidth, with each slot using 6.25 kHz. This reduces transmission time by 50% and extends radio battery life by up to 40%, doubling channel capacity without additional equipment. Its 5–50W adjustable power output and high receiver sensitivity ensure expansive coverage and clear communication in challenging environments.

Analog and Digital Compatibility

The PR900’s smart digital-analog auto-detection seamlessly integrates legacy analog radios, protecting existing investments while enabling a smooth transition to digital. Features like pre-emphasis and de-emphasis in analog mode enhance audio clarity, making it ideal for mixed-system environments.

Flexible Networking Capabilities

The PR900 supports multiple networking options, including IP Site Connect for up to 64 sites, Enhanced Conventional System (ECS) for dynamic channel allocation, and simulcast for large-scale coverage using a single frequency pair. Active Link provides wireless connectivity in areas without IP infrastructure, ideal for remote locations like mountains or forests.

Superior Audio and Security

Digital voice processing minimizes environmental noise, delivering crystal-clear audio in noisy settings. The PR900 supports 256-bit AES encryption, authentication, and remote stun features, ensuring secure and reliable data transmission for critical operations.

Rich Functionality

Beyond PTT services, the PR900 supports text messaging, status updates, map-based location services, and call recording. Its AIS protocol enables integration with third-party dispatch software, enhancing operational efficiency for applications like fleet management or emergency response.
