5. Troubleshooting
If you encounter any issues with your Casio CTK-2400, please refer to the following common solutions:

- No Sound: Check the MAIN VOLUME slider. Ensure headphones are not plugged in if you intend to use the speakers. Verify that a tone is selected.
- Sampling Issues: Ensure you are speaking clearly and close enough to the built-in microphone during recording. Check the sampling volume settings.
- MIDI Connectivity: Ensure the USB cable is properly connected to both the keyboard and your computer. You may need to install appropriate drivers or configure your music software to recognize the keyboard as a MIDI device.
