Store permanently: The new parameters are stored in the unit internal memory. They
will be used immediately and for all the next starts.
Save temporarily: The new parameters are used immediately but are not saved in the
unit internal memory. Next starts will use the old parameters.
Discard changes: The new parameters are discarded. There are no effects.
Do not switch off the Base Unit power supply during parameter
storing. The whole unit configuration might be corrupted and a new
configuration download might be necessary.

parameter set.
Changing the active parameter set is possible only with the protection in the set
