– "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, you must perform a manual RAM
to ROM data backup later if the know-how protection remains deactivated after switching
off and on.
6. Enter your password, and click "OK".
Know-how protection is now deactivated. If larger data volumes are being decrypted, a
progress display informs that the decryption or the deactivation of the know-how protection
is still running. The values of all parameters are displayed again in the expert list.
However, after switching off and switching on the power supply, the password remains
deleted.
