■2.0-inch HD Color Display

The 2.0-inch LCD ensures enhanced accuracy and comfort for the user.

Multiple Operation Modes

DMR Tier III Trunking Mode (TM)

Supports PDT/DMR/NXDN digital protocols, offering capabilities for voice single calls, group calls, broadcast calls,

and a wide range of advanced communication functions. 

Conventional Mode & Repeater Mode (DM/RM)

Digital and analog services on Conventional Mode (DM)/ Repeater Mode (RM)

Advanced Data Encryption

Utilizes the AES256 encryption to ensure the utmost security of communications and enhance information safety.

SFR (Single Frequency Repeater) - for DMR Model Only

Single Frequency Repeater (SFR) technology leverages TDMA (Time Division Multiple Access) to simultaneously rebroadcast

two-way radio transmissions on the same frequency. It achieves this by concurrently utilizing the two time slots of   DMR. Specifically, SFR receives on one time slot while transmitting on the other, enabling efficient and simultaneous communication on a single frequency.

Outstanding Reliability and Durability

Built to the military standards and conforms to the IP68 industrial protection rating. The wear-resistance of it enables it

to perform excellently in a wide range of harsh working environments.

Man Down Switch

The Man-Down tilt switch, housed within the radio, automatically triggers an alarm signal when the radio remains tilted for a set duration. It typically emits warning beeps to alert the user before activating the alarm. This feature is designed to safeguard solitary workers by instantly signaling for assistance in the event of an incapacitating fall, alerting both other users and the control center to initiate help.

Bluetooth Voice/Data Service (Optional)

Equipped with Bluetooth 4.2 standard compatibility, this device supports both Bluetooth-enabled frequency programming and

calling. These features significantly enhance the product's versatility and user convenience.

GPS/Beidou/GLONASS Positioning (Optional)

Features GPS/Beidou/GLONASS positioning, allowing for the transmission of accurate location information. When integrated

with the command and dispatch software, it allows for intuitive mapping of personnel locations and supports voice communication with them.
