If you happen to have one of these units and it all of a sudden fails to work properly here is a possible fix... If by chance anyone has one of this radios in 2019 that all it does is have a high pitch squeal with no weather station reception ...pull batteries out then unplug and hold vol up and weather / snooze button at same time and plug back in, all 3 warning lights will light and you will see the unit display reset then release buttons and your WR -100 will work normally again but you will need to re-enter the SAME code for your areas.
