Marin County Georgia?
I'm sure you mean the BCD396T - anyway, it's really not the software that makes DMA easy to understand; you need to sit down and understand how it works first, in my not so humble opinion...let's address that in a minute (all links are in blue, here and in the wiki)
Anyway, go get a copy of
FreeScan We host the user manual in our wiki
here (it's freeware). You can always go to ProScan or ARC396 later and not have lost anything...
Now for DMA Concepts - go to the blue toolbar under the Scanner Master ad and float your mouse over
wiki. Click on
Wiki home. About 2/3 way down on the right, in the Popular Topics section is a link to the
Uniden DMA FAQ, which will get you started in understanding terms and concepts. At the bottom of the article are the links to the Easier to Read online manuals. Download the one for the 396.
There's a couple of additional recommendations. Up in the Links for Newcomers area, read the Connecting scanners via USB article; this one discusses getting a USB cable and installing drivers. You will need this to make the connection between the PC and scanner. If you are not familiar with trunking, I would read the Trunking Basics article.
Take the time to examine our database and wiki - in the wiki home page, on the left in the Gateways area, click on Collaboration. Follow that to your state (and most state pages have a link for associated counties - I don't know if we have something for your county, but it's worth learning how to navigate). The database can be accessed by clicking on the blue toolbar under the site title on 'database'.
That ought to keep you busy for a spell. 73 Mike
