Hi, djiuser_ksyMBNOOn228. Thank you for reaching out. Please refer to the tutorial video above. Make sure that the new RC is updated as well before you pair it to the drone. You may update it using the DJI Fly or DJI Assistant 2 (Consumer Drones Series). You may download them from this link: (https://www.dji.com/downloads/products/mini-2). Hope this helps. Thank you for your support.
