MD655 Mobile Radio
Intuitive operation
The MD655/MD655G is operated completely via the handheld microphone, which contains all necessary buttons and also an LCD display. On top of that, two buttons can be freely programmed to assign important functions to them.
Compact design
The MD655/MD655G excels through its stylish and particularly compact design. With its dimensions (165 × 46 × 140 mm) and a weight of only 1050 g, the mobile radio can be used in a multitude of ways.
Various installation options
With its operation via handheld microphone, the MD655/MD655G can be installed at any suitable location in the vehicle.
Adaptable transmitting power
Programming the MD655/MD655G allows adapting the transmitting power from 1 W up to 25 W.
Analog and digital mobile radio (dual mode)
In the MD655/MD655G, it is possible to configure analog as well as digital channels. With the channel selection, this enables easily switching between analog and digital.
Improved utilization of the frequency spectrum
Thanks to Pseudo Trunking and the TDMA procedure, the MD655/MD655G allowsassigning the available bandwidth with twice the number of channels. This has a clear mitigating effect on increasing spectrum scarcity.
Expansion interface
Thanks to the expansion interface, the range of functions offered by the MD655/MD655G can be expanded by significant functions. Accessories and applications developed by partners can be connected to this interface.
