This is the power cord for connecting to an outlet that came with the Panasonic TV doorphone indoor unit VL-SWE710KF. Since it was not used during the TV doorphone installation, it is being sold as an unused item. Although it is an accessory for the doorphone, it can also be used for other electrical appliances. I cannot answer questions regarding usage or installation methods, but you can find details by searching online. Please purchase only if you understand the product. Color: White Thank you for viewing.
