Product description

Excellent voice transmission
Thanks to the simultaneous application of narrow band codecs and digital error correction, the MD785/MD785G offers you an outstanding audio quality in loud environments and in boundary regions of the radio coverage.

Dual mode
The MD785/MD785G features an analogue as well as a digital mode and is compatible with the currently used analogue systems, thereby simplifying your transition into the digital age.

Improved use of the radio spectrum
Thanks to the TDMA process the MD785/MD785G allows an assignment of the available bandwidth with double channel capacity. This results in a clear relief of the increasing spectrum scarcity.

Secure communications
Besides the built-in encryption based on digital technology, the MD785/MD785G features advanced encryption options, e.g. 256-bit encryption and a scrambler function (optional).

Reliability and quality
The MD785/MD785G complies with the standards MIL-STD-810 C/D/E/F/G and the degree of protection IP54 and offers a high degree of reliability even in rough environments.

Versatile functionality
Besides the classic communication functions, the MD785/MD785G features numerous additional digital and optional functions, including text messages, GPS location determination* and a lone worker function.

Expansion port
Thanks to the built-in expansion port, the MD785/MD785G can be expanded by additional functions.

Intuitive interface and key guidance
The high-resolution LCD screen offers a clear display, even under difficult light conditions. The large keyboard and ergonomic programmable keys allow an efficient and productive communication.
