I'm A Chicago Fireman who has had analog scanners for 50 years The Chicago Fire Dept switched to digital 2 years ago and with the price of the 996 dropping I bought one today I only want to program 4 freq and for the life of me can't figure out how to do that I read the uniden manual and the manuals buy others yet I'm still lost Can any one explain in simple terms how to do this. Our first scanner had a toggle switch that toggled between 2 crystals, north and south fire. My Father was a fireman and my Mother had the scanner on any time he was a work Denris
