Key features and benefits:

Self-defined Voice Annunciation

The user can directly download voice annunciation of different languages and also zone alert tone to the radio through the PC software based on the actual needs. After powering on, the voice annunciation will automatically switch to the local language.

Compact Size with Clear and Loud Voice

The application of 1W high-power loudspeaker and the technology of advanced digital voice encoding as well as forward error correction make it possible for the user to hear clear and loud voice even in the noisy environment.

Improved Call Capacity with DMO 2-slot.

The feature of DMO 2-slot realizes two group calls on the same frequency at the same time in Direct Mode. The call capacity can be increased without having to apply for additional frequency, thus greatly helping the user to save the cost.

Smooth Transition and Compatibility with Both Analog and Digital Mode

It supports both digital and analog mode, so the user can go on using the existing analog radio to talk to SR-D1U.

Longer Operation Duration

TDMA technology and power-saving feature enable the battery to work longer.

SR-D1U with standard 2000mAH battery can perform for 16 hours to meet the user’s demands on longer operation.

ARC 40-bit Encryption Guarantees Safe Communication

It supports ARC 40-bit encryption, which guarantees communication safety and prevent from being eavesdropped.

Various Digital Signaling

It supports features such as Radio Check, Call Alert, Stun/Revive, Radio Kill, and Remote Monitor, which make radio management easy.

Emergency call, Lone Worker and Man Down (optional).

It supports features including Emergency Call, Lone Worker and Man Down to guarantee user’s safety at all times.

RFID (optional)

Optional RFID does not require manual input/search, greatly improving convenient rental management by easy scanning.

Repeater Description:

As a DMR repeater product with ergonomic design, totally digital functionality, the DR600 helps to improve management efficiency and a faster response in emergency situations.


Professional 1U Design

Professional 1U design saves installation space.

Outstanding Heat Dissipation
The unique cooling design combines a built-in heat pipe and four fans design ensuring  very efficient heat dissipation, preventing the repeater from over-heating in high output power mode.

Smart Digital-Analog auto detection  
DR600 can be configured to analog, digital or mixed mode. When configured to mixed mode, the repeater can dynamically switch between analog and digital depending on the type of call it receives.

Accessory Expansion

DR600 supports third party development via a rear port of the repeater. This is achieved via the pin control through the repeater ports. Sip and AIS protocol supported for easy expansion.

IP Connecting
IP connection is a function which enables repeaters in different areas to switch data, voice and packets over a TCP/IP based network.

LED Indicator
9 LED indicators on the front of panel enables you to identify the repeater status clearly. 

Software Upgradable to DMR Tier2 or Tier3

The advanced features can be upgraded to your existing DR600 repeaters by software without purchasing a new one. By software upgrade, the repeater can be used as a DMR Tier2 repeater or DMR Tier3 transceiver.
