Using your new Bradley touchless sensor faucet is easy. Just wave your hand in front of the sensors, and the water will turn on automatically. For power, you can use the included 4xAA alkaline battery pack as the standard option, or you can connect it to an AC power source with a battery backup. When it comes to maintenance, keep an eye on the low - battery LED indicator on the spout. Replace the batteries as soon as you see the low - battery signal. The PVD finish on the faucet is very durable, but avoid using abrasive cleaners as they might damage the surface. To clean it, use a soft cloth and a mild soap. Make sure to comply with all local water regulations, and if you have any issues, refer to the product's certification information for guidance.
