I'm not really familiar with that model, but what happens when you hit "scan"?
If it is all dashes or something like that (something other than what it looks like under normal, conventional scanning), you are probably trunking, and there is no traffic to follow. If not, maybe you have to hit "trunk" button to turn on trunking. If it's scanning in conventional, you will probably hear the data channel (another thing to check, even if you have "trunking" turned on - make sure you're withing range).
Let us know what the display says once you get it all programmed, and hit scan (trying to follow the system).
If you still can't get it all figured out, next time you're around the Metro (OKC), shoot me a PM - maybe I can meet up with you and help you out.
