General Information

The MR 11 radio family has been designed on a common technical basis. This means: largely the
same components, the same circuit technology, the same software and the same user interface.
The radios are designed both for private mobile radio and trunking systems.
The MR 11 is the mobile radio in this new radio family. There are two models: the C radios with an
integrated control unit for voice transmission and the R radios (without control unit) with connection
facility for external data equipment and control units for voice transmission.
