IKEA Raffinerad Oven Settings

Hello everyone,
our new IKEA Raffinerad oven has been in operation for 2 days now. How can I change the language from English to German?
Unfortunately, I did not find this in the settings on the Raffinerad. Because I have no knowledge of Russian.

Regards

According to the English manual, this should be possible under "Settings," where you also set the time.
Best regards,
IKEA-Freund

Thank you for the response. I have now also found the settings for the sound, the lighting, etc. But I cannot change the language.
