Thanks for your message. But just so you know, I support US products and customers. And from what I can tell, this model is for India. (Correct me if I'm wrong.) So if you want the most accurate information, here's the Samsung India portal for support on that product: http://www.samsung.com/in/support/model/UA40EH5330RLXL
Hope this helps you!
