Using this faucet is easy. Just wave your hand near the sensors, and the water will turn on automatically. The battery pack with 4xAA alkaline batteries is the standard power source, but you can also use the optional AC plug-in adapter. If you choose the battery option, keep an eye on the low battery LED indicator in the sensor package and replace the batteries when needed. When it comes to maintenance, wipe the faucet regularly with a soft cloth to keep the Polished Chrome finish looking great. Avoid using abrasive cleaners as they may damage the finish. Since it's a vandal-resistant design, it's built to last, but still handle it with care. Make sure the water supply is properly connected using the tempered line adapter. If you have any issues, check the indicator lights on the spout to troubleshoot power, activation, or low battery problems.
