MULTI-SYSTEM FLEXIBILITY

The HM782 can be deployed in Analog and Digital Conventional, MPT and XPT Trunking, DMR Tier II and Tier III Trunking, IP Multi-Site Connect, and DMR Simulcast Systems.

CLEAR AND BRIGHT DISPLAY

The HM782 features a 2.4-inch, 240×300 HD TFTLCD display with an intuitive six-grid navigation interface with large type and icons. The display supports 262,000 colors, and is clearly visible in bright sunlight.

LOUDER AND CLEARER AUDIO

Hytera provides industry-leading audio quality through an optimized forward-facing loudspeaker and AI-based voice enhancement with deep learning ability that can accurately extract voice from noise in real time and decreases unwanted background noises as loud as 30db.

HIGHER SECURITY

The HM782 supports Digital End-to-End and Overthe- Air Encryption for voice and data. Hardware encryption is implemented through a built-in encryption card. Advanced software encryption uses the ARC4 and AES encryption algorithms.

SINGLE FREQUENCY REPEATER

SFR mode on the HM782 enables repeater operation on a radio channel that transmits on one slot and receives on another slot using the same frequency. SFR mode extends coverage in field operations with long distances and variable terrain.

WIRELESS LINK

In situations where a wired IP network is unavailable between two repeaters, two HM782 radios using different frequencies can provide a wireless link between the repeaters.

GREATER CALLING FLEXIBILITY

The HM782 supports Individual Calls (radio to radio, radio to dispatcher), Group Calls (one radio to many, dispatcher to many), All Call (broadcast call to all radios, transmit only), and Telephone Calls (with connectivity to PSTN, PABX or SIP networks).

ENHANCED WORKER SAFETY

The HM782 radios are designed for worker safety with an easy access emergency button, emergency calling, and priority interrupt. Lone Worker prompts the user to press a key at preset intervals to indicate they are safe. Large tactile knobs and piano-style buttons provide easy access that keep eyes on the road.

ENHANCED GPS LOCATION TRACKING

The HM782 reports current location information to other radios, the dispatcher, or a third-party applications in real time, enhancing the efficiency of visualized dispatch applications. GPS data is transmitted during voice calls for immediate location targeting, and GPS data can be compressed to increase channel capacity and reduce hardware cost.

DURABLE AND RUGGED

IP54 compliant for water and dust ingress, and MIL-STD- 810 G for shock and humidity.

BACK-TO-BACK

The HM782 can be deployed Back-to-Back to enable communication between analog and digital radios, or radios with different frequencies. Two HM782 radios can be deployed Back-to-Back, or one radio and a repeater can be used.
