MD782 | MD782G

Easy to use digital mobile radio with ergonomic design.

The MD782 and MD782G DMR mobile radios offer versatile digital functions that allow you to exchange information in all types of situations. With their ergonomic design, easy-to-operate user interface and remarkable quality, they are the ideal solution for your communication requirements; regardless of whether you are aiming to optimize the efficiency of your company or be able to respond to emergency situations at all times.

Description

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

Dual mode
The MD782/MD782G features an analog as well as a digital mode and is compatible with the currently used analog systems, thereby simplifying your transition into the digital age.

Improved use of the radio spectrum
Thanks to the TDMA process, the MD785/MD785G enables you to assign the available bandwidth with double channel capacity. This has a clear mitigating effect on increasing spectrum scarcity.

Digital encryption
Encryption using encryption algorithm ARC4 (40 bit) in accordance with DMRA or optional algorithms AES128 and AES256 (128 and 256 bit) ensures secure communication.

Reliability and quality
The MD782/MD782G complies with the standards MIL-STD-810 C/D/E/F/G and meets the IP54 degree of protection. A high degree of reliability is assured even in harsh environments.

Versatile functionality
Besides the traditional communication functions, the MD782/MD782G features numerous digital and optional functions, including text messages, GPS location determination and a lone worker function.

Expansion interface
Thanks to the expansion interface, the range of functions offered by the MD782/MD782G can be expanded to include key functions. Accessories and applications developed by partners can be connected to this interface.

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 facilitate efficient and productive communication.

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