Preventing data reconstruction from the memory card
As soon as know-how protection has been activated, the converter only backs up encrypted data
to the memory card.
In order to guarantee know-how protection, after activating know-how protection, we
recommend that you insert a new, empty memory card. For memory cards that have already
been written to, previously backed up data that was not encrypted can be reconstructed.
