Using this faucet is easy. Just wave your hand in front of the touch - free dual sensors, and the water will turn on. The battery pack with 4xAA alkaline batteries powers the faucet, and you can check the indicator lights on the spout to see the power status. When the low - battery light comes on, it's time to replace the batteries. Remember, this item is non - returnable. To maintain your faucet, clean it regularly with a soft cloth. Avoid using abrasive cleaners as they can damage the Brushed Bronze PVD finish. The PVD finish is very durable, but be gentle to keep it looking great. Also, make sure to follow all local plumbing codes when installing the faucet. It complies with ADA guidelines, so it's designed to be accessible for everyone.
