This is a used item that I purchased new a long time ago. I have confirmed that it works with the AC adapter and dry cell batteries. The nickel-metal hydride battery NH-14WM (gum battery) is missing, and its operation has not been confirmed. Included items: AC power adapter Headphones with remote control Dry cell battery case Instruction manual Three used MINI discs (two of which have been recorded over) - service The main unit is in quite good condition, but please be aware that it is a used item.
