Rob posted improved versions of some of the manuals at
[Link: hifi-remote.com]

He was working mainly with the 15-1994, so he seems to have done the best job with that manual.

Most of the commands are the same between the 15-1994 and most other models, so Rob's improved 15-1994 manual is better documentation for your 6011 than the official 6011 manual is. However, the 15-1994 douesn't have home theater, so you can't get details on the HT commands there.
