The PD785 and PD785G (variant with GPS) handheld radios are designed according to the DMR standard and are characterized by their ergonomic design, extensive digital functions and high quality. They make communication an exciting experience and allow you to quickly react to new situations.

Improved utilization of the frequency spectrum

Thanks to the TDMA process, the PD785/PD785G enables you to assign the available bandwidth with double number of channels. This has a clear mitigating effect on increasing spectrum scarcity. 

 

Ergonomic design

The handheld radios PD785 and PD785G (variant with GPS) by Hytera offer high ease of operation and reliability which is indispensable in critical situations. The worldwide patented industry and antenna design makes them convenient to use and provides remarkable GPS properties. 

 

Versatile services

In addition to conventional communication services, the PD785/PD785G offers extensive data services and functions, such as text messages, scanning, emergency calls, Man Down alarm (optional) and lone worker functions.

 

Reliability

The PD785?/?PD785G meets all the requirements of the open ETSI standard DMR as well as MIL810-C/D/E/F/G and degree of protection IP67. The device series thus offers excellent features even under harsh operating conditions.

 

Ease of use

Large pushbuttons ensure the handheld radio is easy and convenient to use. The large TFT color display enables good readability even when light conditions are poor. More than 20 programmable keys allow quick access to the various services and functions.

 

Powerful battery

Compared to the analog technology and the FDMA process, with TDMA the battery service life can be improved by approximately 40%.

 

Excellent voice quality

With the combined application of the narrow band codec and digital technologies for error correction, the PD785/PD785G ensures excellent voice quality even in loud environments and in peripheral areas of radio coverage.

 

Upgradeable software

Upgradeable software enables the possibility of new features. By altering the firmware-software, other digital and analog operating modes can be enabled, without the need for purchasing a new radio device.
