This is a junk item! As shown in the second photo, the back panel is detached. Operation has not been confirmed. I received this from my father during my student days, but I wasn't interested in it and left it unused at my parents' house. It was found in the storage room during a decluttering of my parents' house. Use it for parts! As stated at the beginning, this is a junk item, so please purchase only if you understand this! Also, returns are not accepted. No claims, no returns, please!
