- Storage: Store the controller in a clean, dry environment away from direct sunlight and extreme temperatures.
9. Troubleshooting
If you encounter issues with your Haute42 S16-C controller, consider the following troubleshooting steps:
- Controller Not Recognized: Ensure the USB cable is securely connected to both the controller and the system. Try a different USB port or cable. Verify that the correct controller mode is selected for your system (if applicable).
