Using your Bambury King Single Standard Electric Blanket is easy. Just plug in the detachable controller, and use the raised dot indicators to select one of the three heat settings even in the dark. To keep your blanket in good shape, make sure to detach the controller before washing. The blanket has an overheating safeguard system, but it's still a good idea to avoid folding it tightly while it's in use. When storing, keep it in a dry place. This blanket comes with a 2 - year warranty, so if you have any issues, reach out to the customer service. Enjoy the warm and cozy nights with your family!
