Sorry but no there is no reset button on any of those radioshack models try going back to the original spot that you had it connected to and see if it works if not then there are 2 thing it could be 1 the power supply went bad second is that when you unpluged it (guessing that you didn't turn off the scanner) that when you unpluged it you sent a surge through the pc board and poped a diode you can send it out to be checked and or repaired by radio shack at any of there locations can handle your needs
