Using this hand dryer is a breeze. Just place your hands under the dual air outlets, and the automatic sensor will detect them and start the drying process. It'll quickly dry your hands for you. When it comes to safety, always make sure to use it within the specified power range (208 - 240 AC). Don't try to modify the dryer on your own as it may void the warranty and pose a safety risk. For maintenance, wipe the stainless - steel cover regularly with a soft, damp cloth to keep it looking clean and new. If there are any stubborn stains, use a mild detergent. And remember to check the power cord periodically for any signs of damage.
