To all the noobs...don't
ever feel like you are asking a dumb question. Granted, if you are asking a tech support question with absolutely no information accept for "Help!"...that is a different story.

Sonobouy called it right. When you first get the trace 50hz tonal, assign it for
initial information. Granted, since the DEMON information won't be taken from NB stuff, you won't have the correct speed. But, utilize course changes of your own and you can get a better estimate on range. Once you can get the BB trace, drop the NB tracker and assign one to your BB display.
Lastly, go to subguru's site for TimmyGoo's manual or quite a few others!
