Product Information
  • Overview
  • More info
No matter for which application, the DMR mobile radios MD655 are compact and user-friendly and, as a result, your reliable companion for secure communication. Besides their outstanding voice quality and reliability, they excel through their simple operation via the handheld microphone.

Intuitive operation
The MD655 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 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 can be installed at any suitable location in the vehicle.  
Adaptable transmitting power 
Programming the MD655 allows adapting the transmitting power from 1 W up to 25 W. 
Analog and digital mobile radio (dual mode)
In the MD655, 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 allows assigning 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 can be expanded by significant functions. Accessories and applications developed by partners can be connected to this interface.
