My pro 404 seems to not recieve any rADIOfrequencies. When i firs bought the device several months and programed the frequencie of the local police station, the scanner recieved the frequencie loud and clear from 6 and half miles away.   i programmed many frequencies of multiple agencvyies. Aaand wont recieve any rADIO transactions after scanning throgh the channels. I am looking for some advice or a pdff ccopy of the manual to download the file. Thnk you reply to me at zdonaldson@live.com
