I have the same problem. I downloaded the Plantronics Hub software, but when I set it to German, it first displayed a successful message, but it is still set to English US. I have now contacted support.

Hi Johni
Download the PC software HUB (https://www.plantronics.com/ch...) and then the native settings on the Legend, where you can set the language. Otherwise, if you have any questions, call 0800 932 340 ;-)

Try the following steps: http://www.ligo.co.uk/blog...

PS: Make sure you start the software as administrator (right click on icon).

PPS: Otherwise, contact the manufacturer directly for further product support.
