The PDF Manual can be found at

but be warned if you want to print it, it is over 500 pgs long!
Download the file appropriate for your OS, then run the file. After the file runs (which will take about 2 seconds), look for the folder called "pml_-win-mx920-1_2-en" (in whatever directory the download is in). The manual is in there.
