Highlights

diagram indicating highlights of HM785

Function Button

Patented button structure design provides greater feedback to the operator with 6 programmable keys for customised operation for quick access to features used on regular basis.

Faster Cooling

Improved case design improves heat dissipation to improve cooling when using higher transmit power levels.

Screen

2.4-inch colour screen with simple UI interaction to improve operation.

High Reliability

Textured features make it easier to distinguish each functional area. The frame has a greater wear resistance and enhanced screen design provides greater reliability.

Scalable ports

Accessory Port and Ethernet Port provide connectivity to external accessories and other devices

IP Transit Solution

First ever Hytera DMR radio that can support the IP Transit Solution feature

Functions

Created with Sketch. 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).

Created with Sketch. 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.

Created with Sketch. More Reliable

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

Created with Sketch. Rich Scalable Application

Supports multiple connections through BT, and the accessory and network (Ethernet) ports. It also supports Clarity Transmission and back to back connections which will greatly facilitate your solutions.
