hi orangesporanges and thanks for answering, i downloaded BT Plugin roundup, however, i have no idea what it is? sorry to be so dense.

Just from hovering over it it seems to be a PDF file which is essentially a test/image document like the Sonar manual.
 
You will not be able to open it unless you have a PDF viewer such as Adobe Acrobat installed on your computer (I recommend Adobe Acrobat personally which is free for the base version and will work but there are of course others).
 
Browsers such as Firefox can also display PDF documents if you have the right browser plugins (I think Acrobat installs itself as a PDF reader in Firefox and other browsers as well).
 
Pretty much all the manuals I encounter online are in (or available in) PDF format so it's worth figuring that out.

Yeah, it's just a pdf of all of the blue tubes plugs. I think it was assembled awhile back by one of the users who was having trouble finding good documentation for the line. I just clicked on my post and it opened right up. I'm using Google chrome and a free .pdf reader. Good info in there. May be worth getting a reader to open it. Bunch of free ones.
