If you are experiencing performance issues with your AM/FM radio, there are several options available to try and solve the issues. The specific methods for solving the problems depend on what type of problem you encounter and the model of radio with which you are working. Some methods, on the other hand, are pretty much the same no matter the model.
Check the power cord to see whether the radio is plugged in to an electrical socket. If the cord is unplugged or loose in the socket, securely plug in the radio. Check the battery compartment on the back of the radio to ensure that the batteries are in when the radio is unplugged. If the radio does not turn on even with batteries in, remove the current batteries and put in fresh batteries.
