You need to check the manual of the file, because I've searched everywhere and there is no information related to language change support. The only files that I found are datasheets, some sort of presentation PDFs with details about the product, but nothing is shown exactly regarding the built-in menu.
You can also do it the hard way and blindly check the menus until all the languages are displayed. I've done this with a few of my devices and it worked at some point.
