Using this faucet is easy. Just wave your hand near the sensors for touch-free activation. Make sure to keep the area around the sensors clean for smooth operation. When it comes to power, the included battery pack with 4xAA alkaline batteries is the standard source. You'll see indicator lights on the spout. If the low - battery light comes on, replace the batteries promptly. This faucet is made to last, but for maintenance, use a soft cloth to clean the polished chrome finish regularly. Avoid using abrasive cleaners as they may damage the surface. And remember, this item is non - returnable, so handle it with care.
