Using your NOOSA LED oval frameless mirror is a breeze. For the push - button function, to turn on the light, just press the button. You can then select between cool/day or warm light to suit your needs. When you're done, hold the button until the light goes off. If you want to use the motion sensor, first press the button to turn on the light and pick your favorite light color. Leave the light on that color and step away from the mirror for 60 seconds. The light will turn off on its own, and the button will turn blue, meaning the motion sensor is now active. Wave your hand in front of the sensor to check if it's working. When you leave the area, the mirror will automatically turn off after 60 seconds. As for maintenance, keep the mirror clean with a soft, dry cloth. Avoid using abrasive cleaners that could scratch the surface. This will help keep your mirror looking great and working well for a long time.
