What should I do if the RK100 is causing interference with my radio or TV reception?

You can try to resolve the interference by reorienting or relocating the receiving antenna, increasing the separation between the keyboard and the receiver, or connecting the equipment to an outlet on a different circuit. If the issue persists, you are encouraged to consult the dealer or an experienced radio/TV technician for help. (Page 2)
