Using this faucet is easy. Just wave your hand near the sensors for touch - free activation. The indicator lights on the spout will show if it's powered, activated, or if the battery is low. When it comes to the battery, use the included pack of 4xAA alkaline batteries. Replace them when the low - battery indicator lights up. Keep the faucet clean by wiping it regularly with a soft cloth. Avoid using abrasive cleaners as they can damage the Brushed Stainless PVD finish. This faucet is designed to meet ADA guidelines and is lead - free, so you can use it with confidence in your kitchen or bathroom.
