My Pro-106 has been working beautifully. I turned it on yesterday and it would not function properly. The LCD display shows one frequency, it "beeps" continually, and I cannot get it to scan normally. I have tried the various remedies using the power-on configuration key sequences. I have been unable to get it to scan, program, or anything else. The LCD display does not change except when I am in the process of doing one of the power-on key sequences when a new mwssage will appear briefly, then go back to the one display that it is stuck on. I have changed locations by several miles to no avail. I have used different power supplies without effect. Can anyone tell me if there is a remedy short of taking it back to RS for repairs? Thank you for any suggestions. Paul
