This CD radio player can be used for language learning and in case of disasters. It runs on an adapter or six size-D batteries. (Batteries not included) We have confirmed that the power and radio function of the main unit work when using the adapter. There are some minor scratches that are not very noticeable, so please consider purchasing if you don't mind. Since it will be handed over without the box, the price is set lower than the market price. #radio #CD #player #CDR-550SC #language #disaster #Bearmax
