- Instant push-to-talk individual and group calling with radio identification.
- Doubles the capacity of existing licensed radio channels.
- Provides efficient use of infrastructure equipment.
- Enables power efficiency for longer battery life.
- Superior audio performance with digital background noise suppression.

Feature Definitions
Definitions for various features and specifications.
| Feature | Definition |
|---|---|
| Frequency Bands | These are the frequencies within the radio spectrum supported by the radio and enables deploying the radios in areas with these frequencies available. |
| Channels Analog / Digital | The number of channels that can be utilized for simplex (one way at a time) radio calls. |
| Zones | A method of grouping and organizing channels for multiple users. |
| RF Output Power | The transmission power of the radio that enables the communications distance. The higher the power, the longer the distance and transmission through barriers. |
| DMR Digital Noise Suppression | The voice encoder (VODEC) digitally processes the audio and eliminates background noise. This is specified as part of the DMR standard, and Hytera provides additional digital enhancements to audio quality. |
| AI-Based Noise Suppression | Audio is processed using Artificial Intelligence to learn and extract human voice from background noise in real time. |
| Pre-Defined Text Messaging | The radio can receive and display pre-defined text messages from dispatching application or other radios. Provides a way to notify employees of common instructions without radio conversations. |
| Free Form Text Messaging | The radio has a full keypad that allows users to send free-form alpha numeric texts. |
| Programmable Buttons | Buttons on the top or side of the radio that can be customized for different functions such as emergency calls, and lone worker response. |
| GPS | Allows tracking of the radio location with Global Positioning System so dispatchers can see user locations to track vehicle assets, coordinate field operations, and improve worker safety. |
| Bluetooth | Bluetooth support allows wireless communication between the radio and external accessories such as earpieces, microphones, and push-to-talk buttons. |
| IP Rating | IP rating specifies how the radio resists water and dirt penetrating the housing of the radio. IP54, IP55, IP67, and IP68 provide incremental improvements with IP68 as the highest available protection. |
| MIL-STD 810 C/D/E/F/G | MIL-STD-810 is the performance and manufacturing guidelines set by the US Department of Defence for military and commercial equipment. The military standard specifies operational compliance for temperature, shock, vibration, and humidity. |
| Analog/Digital Scanning | The radio can scan other channels for calls based on user defined time periods. Can scan both analog and digital, or either analog or digital channels. |
| Voice Activated Microphone (VOX) | Voice Activated Microphone enables hands-free voice activation of the microphone. Can be supported on the radio only, or on the radio and push-to-talk microphone accessories. |
| Conventional Digital/Analog Repeaters | Can be used with conventional DMR Tier II repeaters that support both digital and analog operation. |
| Pseudo Trunk Operation | In DMR transmissions there are two slots per channel (two data paths 25/2.5Kh spacing). Pseudo trunking allows a radio to use a free slot for a call and increase channel capacity. |
| Extended Pseudo Trunk (XPT) | XPT is built from multiple Hytera DMR Tier II repeaters at a site connected to each other by a simple network switch, making the system more efficient to provide more channel capacity without an FCC management channel or additional radio infrastructure. Available for single and multi-site deployments. |
| IP-Transit | IP Transit is a feature that allows mobile radios in dispersed locations to be connected to exchange voices, data and control packets to each other over TCP/IP protocol, extending the communication network. |
| DMR Tier III Trunking | DMR Tier III support radio trunking that operates under individual licenses with a controller function that automatically manages and optimizes the radio communications channels. Tier III enables voice, text messaging, and packet data services in a variety of formats. |
| Radio Registration Service (RRS) | Allows a dispatching application to see when a radio is switched on or off. |
| Roaming | Allows mobile terminals to seamlessly and automatically move between sites in an IP connected repeater system. |
| Digital Encryption | Used to mitigate the threat of interception by providing the Confidentiality service. Provides several security services including: Confidentiality (the protection of message contents from disclosure), Authentication (the verification of the identity of message sender), and Ensure message Integrity (the message contents have not been modified). |
| Hardware Encryption | The radio will realize encryption via the radio hardware (SD card). |
| Analog Scrambler | The Analog Scrambler provides secure transmission and reception of analog radio transmissions. It transposes or inverts signals or otherwise encodes voice transmission to make the message unintelligible at a receiver not equipped with an appropriately set descrambling device. |
| Emergency Calling | Enables a single emergency call to be broadcast to all radios simultaneously. Send and receive. |
| Emergency Button | A button that alerts dispatch or triggers an emergency all call message to all radio users. Emergency buttons can be a programmable button configured as an emergency button, or a dedicated emergency button located on the top of the radio. |
| Priority Interrupt | Priority Interrupt allows a dispatcher or select radio users to interrupt existing radio calls with important emergency information. |
| Lone Worker | Lone Worker requires a user in a remote location to press a button when the radio provides an audio alert to notify dispatch that the worker is OK. |
| Remote Monitor | Allows dispatchers to remotely monitor radio communications of users in emergency situations. |
| Stun / Revive | Allows dispatch to stun (disable) a stolen or missing radio, and to revive (re-enable) the radio if located. This is used to maintain the privacy and security of communications on the radio network. |
| SIP Phone | The radio can communicate with phones via the Phone feature. |
| DTMF Dial | The DTMF (Dual-Tone Multi-Frequency) encoding technology uses two specific tones (high and low) to represent a number, so as to realize some features. After accessing the phone system, the radio can send or receive phone calls, which are based on the DTMF signaling. |
| OTAP (Over the Air Programing) | Radio can be automatically programmed over the air using the OTAP application for fast and efficient upgrades. |
