Leica DFC Series Manual page 26

Each configuration is valid for any camera of the same
model. This means that you can create a configuration
with one Leica DFC280 and load it using another Leica
DFC280. However, you cannot load a configuration
created on a Leica DFC280 for use with a Leica
DFC300FX, for example.
