(it's kind of piggy, so give it five minutes to load or save it to your desktop)
Or you can lay down $5 for a hard-copy. It might improve your re-sale value to have one on hand:

-or-
You could contact Kenwood on their site and obtain a login and get all the Kenwood manuals you could ever ask for:
http://www.kenwoodusa.com/support/simple.aspx?men=2&M2=38&M3=81
ftp://upload.kenwoodusa.com/pub/manuals/
That should do it and then some!
