The MIN is used to identify an medium (s. Tab. 3.1). But many types of media have different types of numbers. Even the same media type can have different numbers in different regions, also some media have more than one type of numbers.
If you change the MIN of a medium, the system tries to detect the type of the number and set it accordingly. But it can be, that the type you want to use, is not supported by default. So you can add a new type and you must than manualy select this type. If the system knows, which type you entered, it also tries to validate your entered number.
