Hello everyone!!

I've just bought second hand a Satura e Ext, I think its the old model, white and clear brown/golden and I bought it in german language and can't change screen to english.

I tried reset of screen (lef, down and first button on the left) but it doesn't get me to the initial setup.

Is it possible to change it? maybe updating firmware? anyone could help me?

Thank you!

I don't know that model, some firmware downloads for different display models are available on https://www.kettlerworldtours.de/de/main/software/downloads.html, perhaps one of them works for your device.
