7. Select whether you want to deactivate the know-how protection "Temporarily" or
"Permanently" by clicking the corresponding checkbox.
– "Temporarily" deactivating: Know-how protection is active again after switching off and
switching on.
– "Permanently" deactivating: Know-how protection remains deactivated even after
switching off and switching on again.
If you select "Permanently", you can also carry out a data backup on the Control Unit with
"Copy RAM to ROM". The checkbox with the same name is active in this case and is
automatically activated. If you deactivate this checkbox, then you must backup the data
manually later with "Copy RAM to ROM" if know-how protection should remain
deactivated after switching off and switching on again.

Know-how protection is now deactivated. The values of all parameters are displayed
again in the expert list.
