User guide


Q. What to do if one of my screens is blurred?

There is sharpness button in the menu just for that.

Q. I see wrong charaters in some files. What to do?

Make sure your ebooks are UTF-8 encoded. You can do so by opening them in windows notepad and saving them as files with UTF-8 encoding.
For fb2 books you also should correct declaration. ebubs are by default in UTF-8, but epub format is not properly supported.
