Using this faucet is easy. Just wave your hand in front of the sensors for touch-free activation. The indicator lights on the spout will show you the power status and when the battery is low. When the battery is low, replace the 4xAA alkaline batteries. Keep the faucet clean by wiping it with a soft cloth regularly. Avoid using abrasive cleaners as they may damage the polished chrome finish. This faucet is ADA - compliant, so use it with confidence. Also, since it's non - returnable, make sure it meets your needs before installation.
