Operation confirmed. It plays, but there is sound coming from the unit while playing. There is noise when listening through headphones. I can't confirm with speakers, so I don't know if there will be noise from the speakers as well. The jog dial is sticky, and the inner sponge has deteriorated, but the body seems to be clean. Due to the above condition, this is for those who understand it as a junk item.
