INCREASED COVERAGE RANGE

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

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

EMERGENCY ALARMS

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

ANALOG & DIGITAL AUTO-DETECT

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

PRE-PROGRAMMED TEXT MESSAGING

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

ROAMING

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

DIGITAL ENCRYPTION

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

RADIO REGISTRATION SERVICE

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

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.

DMR TIER II

The MD622i can be deployed on DMR Tier II systems
