Using this Bradley touchless faucet is easy. Just wave your hand in front of the sensors, and the water will start flowing. The dual - sensor system ensures quick and reliable activation. For power, you can either use the standard 4xAA alkaline batteries that come with the faucet or connect it to an AC power source with the optional adapter. If you choose the AC option, the battery backup will keep it working in case of a power outage. When it comes to maintenance, keep an eye on the low - battery LED indicator. When it lights up, replace the batteries promptly. The PVD finish on the faucet is very durable, but it's still a good idea to clean it regularly with a soft, damp cloth to keep it looking its best. Avoid using abrasive cleaners as they can damage the finish. Also, make sure to follow all the ADA and safety guidelines during installation and use.
