Using this hand dryer is a breeze. Just place your hands under the dryer, and the infrared sensor will detect them and start the drying process automatically. You can adjust the air speed and temperature settings to your liking. If you don't need the heat, simply turn off the heating option. When you're done, remove your hands from the sensor area, and the dryer will stop. For maintenance, keep the dryer clean by wiping it with a soft, dry cloth regularly. Avoid using abrasive cleaners as they might damage the satin stainless steel finish. Also, make sure the power supply matches the specified voltage (115 - 120V or 277V) to prevent any electrical issues.
