This is a listing for the main unit, adapter, protective panel, and dedicated case. There is no manual, so I performed a basic operational check using headphones. I confirmed sequence playback, sound changes via knobs, and button operation. There are many scratches on the back of the main unit. Since I cannot confirm all functions, this is being sold as-is. To prevent product substitution, cancellations or returns are not accepted after purchase. Thank you for your understanding.
