Using your Bambury's Standard Electric Blanket is easy. First, spread the blanket evenly on your king - sized bed. Plug in the controllers and choose your desired heat setting using the raised dot indicators. You can use the dual controllers to set different temperatures for each side of the bed. When it's time to clean the blanket, simply detach the controllers and wash the blanket as per the care instructions. Remember to always use the blanket on a flat and dry surface. Don't fold or bunch the blanket while it's in use to avoid overheating. Keep the blanket away from sharp objects that could damage it. If you notice any issues, contact our customer service within the 2 - year warranty period.
