Using this faucet is easy. Just wave your hand near the touch - free dual sensors, and the water will turn on. Make sure to install the 4xAA alkaline batteries in the battery pack, which is the standard power source. The indicator lights on the spout will let you know if the faucet has power, is activated, or if the batteries are running low. When it comes to maintenance, since the PVD finish is very durable, you can simply wipe the faucet with a soft cloth regularly to keep it clean. Avoid using abrasive cleaners as they may damage the finish. As it's a non - returnable item, make sure to check it thoroughly upon delivery. Also, note that it complies with ADA guidelines and is lead - free, so it's safe and accessible for all users.
