Hytera HM785 High Power 50W DMR mobile radio UHF

The HM785 DMR mobile radio is the next generation of professional digital mobile radio providing greater flexibility and scalability. This mobile radio with DMR technology supports a single control head as standard with options for remote control head mounting and dual control head to suit different environments (such as vehicles, motorcycles and fixed control rooms) ensuring efficient communication. The new UI interface facilitates faster operations and the AI-based noise cancellation technology guarantees clearer voice even in the noisiest environments. It is also the first ever DMR radio that can support the IP Transit Solution feature. It comes with a rich digital mobile feature set including a broad range and ability to integrate into existing services, which provides greater efficiency.

MORE FLEXIBLE

Flexible control heads and accessories allow installation according to the users requirements. The connection cable of the remote control head can be either 3m, 10m or 40m as standard. A connection cable of up to 120m is also available (Customisation required).

CLEARER AUDIO

Adopts AI noise cancellation technology to filter out background noise (such as road noise), eliminate echoes, enhance speech and reduce howling when in close proximity to the transmitting radio. With this technology, the mobile radio provides crisper and clearer audio when transmitting and receiving voice calls.

MORE RELIABLE

Improved receiver sensitivity improves audio quality in weak signal areas to provide clearer audio
