Software updates
As part of the statutory warranty (2 years from the transfer of risk of the goods – under
German law), we will provide appropriate updates to correct defects. Generally,
updates are used for security-related aspects or to eliminate functional impairments
and do not include new functions of the software. Insofar as the provision of new
functions is necessary to remedy security aspects, this shall not in principle constitute a
claim to new functions as such.
After the legal warranty period has expired, we will of course endeavor to provide you
with appropriate further updates. However, there is no entitlement to this.

specialist retailer, your local distributor or our Customer Service.
