TR850Professional 3U Design

Professional 3U design leaves enough space for an added duplexer and is suitable for both desk-top, cabinet and rack installation.

TR850Outstanding Heat Dissipation

The unique cooling design combines a built-in heat pipe and an intelligent control fan, ensuring  very efficient heat dissipation, preventing the repeater from over-heating in high output power mode.

TR850Smart Digital-Analog auto detection

TR850 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.

TR850Accessory Expansion

TR850 supports third party development via a rear port of the repeater. This is achieved via the signal streaming and pin control through the repeater ports.

TR850IP Connecting

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

TR850LED Indicator

There are 9 LED indicators on the front of panel to enable you to identify the repeater status clearly.

TR850Software Upgradable to DMR Tier2 or Tier3

The advanced features can be upgraded to your existing TR850 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.
