Using your new Bradley touchless sensor faucet is easy. Just wave your hand in front of the sensors, and the water will start flowing. It's powered by 4xAA alkaline batteries that come included. Keep an eye on the indicator lights on the spout. A green light means it's powered on, and when it's time to change the batteries, a red light will show. When it comes to maintenance, avoid using abrasive cleaners on the Brushed Nickel finish as it could damage the surface. Just use a mild soap and water to clean it regularly. Also, since it's a non - returnable item, make sure to double - check your purchase before finalizing. And remember, this faucet is designed to meet ADA guidelines, so it's accessible for everyone.
