Using this faucet is easy. Just wave your hand near the sensor for touch - free activation. Make sure to keep the area around the sensor clean so it can work properly. When it comes to the batteries, replace the 4xAA alkaline batteries when the low - battery indicator light comes on. For maintenance, wipe the faucet regularly with a soft, damp cloth to keep the polished chrome finish looking shiny. Avoid using abrasive cleaners as they can scratch the surface. Also, since it complies with ADA guidelines, it's designed to be user - friendly for everyone. And because it's lead - free, you can have peace of mind about the water quality.
