Functions

Created with Sketch. High Quality Audio

Audio equalizer adjusts low, mid, and high frequency gain. Provides the best audio performance in noisy or quiet environments

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)

Enables real-time location tracking for dispatch applications (requires external GPS module and GPS antenna)

Created with Sketch. Bluetooth Audio (Optional)

Wireless connectivity to audio devices to improve user experience.

Created with Sketch. Reliable and Durable

The MD622i is compliant with MIL-STD-810 G for impact strength and durability, and IP54 water and dust ingress

MD625 1

Created with Sketch. Increased Coverage Range

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

Created with Sketch. Analog & Digital Auto-Detect

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

Icon 24px Created with Sketch. Analog Signaling

Supports HDC1200 signaling for Caller ID and Emergency Calls in analog mode, and is compatible with MDC1200 signaling used by other analog radios. The MD622i can decode DTMF tones while in analog mode for Caller ID signaling

Created with Sketch. Pre-Programmed Text Messaging

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

Created with Sketch. Emergency Alarms

Emergency Alarms can be sent to other radios via the one touch emergency button. mproves worker safety and emergency

Systems and Network

Created with Sketch. Roaming

This feature enables 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. Digital Encryption

Ensure your radio transmissions are secure with end-to-end encryption

Created with Sketch. DMR Iter II

The MD622i can be deployed on DMR Tier II systems

Created with Sketch. Radio Registration Service

RRS allows the MD622i to communicate with dispatch and unified communications applications
