Freeplay Self Powered AM/FM Radio Solar Crank Clear See Through NEW Vintage RARE

Enjoy music on the go with this clear self-powered portable radio. Perfect for outdoor adventures. New with the tag!! I cranked the machine, cranks are moving all knobs move, turns off and on, no sounds are coming from machine? I’m not sure if I am not doing something correctly. Maybe I don’t have a signal, unsure.
