Functions

Created with Sketch. Bluetooth Audio (Optional)

Wireless connectivity to audio devices to improve user experience.

Created with Sketch. Dual Mode

Operating in Analogue and Digital mode to aid your migration from Analogue to Digital two-way radio technology.

Created with Sketch. GPS (Optional Accessory)

Global Positioning System, enabling location based services to improve safety and control.

Created with Sketch. RELIABLE AND DURABLE

The MD612i is compliant with MIL-STD-810 G for impact strength and durability, and IP54 for water and dust ingress

Created with Sketch. INCREASED COVERAGE RANGE

With a high RF power output up to 50W, the MD612i dramatically extends communication range

Created with Sketch. Roaming

This feature allows the radio to switch between sites, ensuring seamless communication.

Created with Sketch. Pseudo Trunking

Using pseudo-trunking, a Hytera patented technology, communication slots can be shared to improve capacity usage with transmissions either direct to devices or to repeater.

Created with Sketch. Emergency Mode

Raise an alarm with top priority to a base station or to other radios with the pre-programmed emergency mode, identifying the ID of the person issuing the alarm.

Created with Sketch. Digital Encryption

Ensuring your radio transmissions are secure with end-to-end encryption.

Icon 24px Created with Sketch. ANALOG AND DIGITAL AUTO-DETECT

Simultaneously monitors analog and digital modes and automatically responds in each mode

Created with Sketch. PRE-PROGRAMMED TEXT MESSAGING

One-touch sending of up to ten pre-programmed text messages

Created with Sketch. RADIO REGISTRATION SERVICE

RRS allows the MD612i to communicate with dispatch and unified communications applications

Created with Sketch. DMR TIER II

The MD612i can be deployed on DMR Tier II systems

Created with Sketch. ROAMING

Allows radios to seamlessly move between connected repeaters with uninterrupted voice transmission
