DENON DN-S700 Operation not confirmed. Power on only confirmed. When a CD is inserted, an error disc is displayed. Also, there is a problem with the ejection system (opening and closing). I have no knowledge of this product, so I cannot judge the condition. This is an unwanted item and has not been maintained, so it is considered junk. How about it for someone who can do maintenance? As it is a used item, there are stains and scratches. Please note that we cannot completely clean it.
