new user sds 100 scanner

Feb 18, 2010
I'm totally new to the scanner world. I just got the sds 100 and am trying to learn little by little. I ran the sentinel software as the video showed a few times. Now my scanner is scrambled. My EMS is in Fire and Air is in Law etc. How do I redo the placement correctly. Also when I added some channels they are listed on the scanner but no transmissions come out.
