The instruction manuals are available in PDF format. A mouse click on the language of the manual shows the corresponding manual in the PDF reader of the browser. Alternatively, you may download the PDF by right-clicking on the file name and then “Save target as…” and save it locally on your computer.

To open the locally stored PDF, you need a PDF reader, e.g. the free Adobe Acrobat Reader, which you can download here. In addition to this reader, there are a large number of PDF readers available free of charge, which can easily be found via an internet search.
