History of the Software Versions and Hardware Changes

The software of the medinCNO

consists of various software packets: Part of them determines the operating

properties of the medinCNO

, the alarms and the functional range. The display macro version establishes the

possible display languages. In doing so, each SW version is dependent on a particular version of the display

macro.
