I have what is most likely a very basic question about programming this scanner. Using ARC996 I can program the frequencies/system I want. The problem is that after going through the system, the unit proceeds to start scanning through what seem to be pre-programmed banks starting with Public Safety, Ham, etc. I've tried just about every thing I can think of to turn these off. I'm using the quick keys. I know I'm missing something that's got to be very basic. I apologize if this has been covered before. I tried to search this site for info but I didn't find any, mostly because I really don't know how to phrase it.
