I purchased this used about two years ago and primarily used it as a monitor controller. It has not been used outdoors. I am selling it because I purchased a new monitor controller. It is a used item with a general feeling of use. There are scratches on the side panels, so please refrain from purchasing if you are looking for a beautiful item. I checked the operation before listing, and there are no major problems. There is a possibility of some crackling that I haven't noticed, but it will be sold as is unless there is a malfunction such as the power not turning on. I do not have a D-sub cable, so D-sub connection has not been confirmed. The items for sale are the main unit, two booklets, an AC adapter, a 3P power cable (non-genuine), and the original box (with signs of use).
