Using your NOOSA 52 DC ceiling fan is a breeze. First, make sure it's properly installed on your ceiling. Then, use the included remote control to turn it on and select from 6 different speeds. You can also adjust the direction of the fan, use the dimmable feature, and set the timer or night mode according to your needs. When it comes to battery replacement, the fan uses 2 AAA alkaline batteries. As for maintenance, keep the fan clean by dusting the blades and enclosure regularly. Avoid using abrasive cleaners that might damage the ABS and UV - resistant materials. If you encounter any problems, refer to the downloadable instruction manual or contact our customer service. Enjoy the cool air from your NOOSA ceiling fan!
