This is what our expert Chris Whitehead wrote to those that contacted him:

I would reccomend you wait until we issue this upgrade on our site as the
installation is slightly different to previous keyboards. Doing this
procedure wrong could stop the keyboard from working. Also we are currently
evaluating this version. It will be posted on the www.technicskn7000.com as
soon as we have done english instructions and have finished evaluating it.

Best Regards
Chris Whitehead"

The Jeapordy is that the keyboard could stop working.
