How to use ALCI plugs correctly: For safety reasons, our hair dryer is equipped with a leakage protection plug. The plug has two buttons, the yellow one is the test button. When there is a danger, you need to press the test button, now the LED light will light up once, which means the hair dryer has been powered off. That means the hair dryer is not working now. The red one is the reset button. You need to press the reset button to restart the hair dryer.
