This item has been stored in a closet for a long time. I'm not sure how to use it, and I haven't used it, so I'm putting it up for sale. The main unit, adapter, and other included items are still in their unopened bags. Therefore, I haven't checked if it works. If you'd like, I can open the bags and check the operation before you buy it. The instruction manual includes a warranty card from 2011, but the warranty period has expired. Please understand the above before purchasing.
