Thank you for viewing. I have only confirmed that it powers on, and no other operations have been checked (sold as is). Since the operation has not been confirmed, this is being sold as junk. Power adapter included. I am an amateur and do not have expert knowledge. Please understand that I cannot answer specialized questions. The main unit has some dirt. Please check the condition of the product in the photos. For those who can repair it or use it for parts. Please understand that this has been stored at home for a long time. Please refrain from purchasing if you are nervous about the condition. Returns and refunds are not accepted for junk items. Will be shipped via Mercari delivery. Immediate purchase without comment is OK. Thank you very much (^_^)
