Here's a link that directly downloads a Cybook Odyssey User's Manual in PDF format:
http://www.mff.cuni.cz/fakulta/lib/pdf/Cybook_navod.pdf
Save it after it downloads. It's 40 pages, approximately 5.8 MB.
Don't know if it will help ... I know ZERO about the Cybook Odyssey. The name sounds like it should be the title of a SF movie.
