radio on 6000 radio/cd player?

Hello all I hope you may be able to help me as I have just fitted the above and everything is connected and antenna (aerial) is fitted and working fine. The cd works great,BUT when I try and put the radio on I cannot get any radio station's to works as at times I heard noise but no radio station found. I have done scans for all stations on all wave bands and news, but comes up with non found. Plus do you know how to set to the clock etc please cheers from David.
