Maintenance
Proper maintenance ensures the longevity and optimal performance of your keyboard:
- Cleaning: Use a soft, dry cloth to wipe down the keycaps and keyboard surface regularly. For deeper cleaning, you may use a can of compressed air to remove dust and debris from between the keys. Avoid using harsh chemicals or abrasive materials.
- Keycap Removal: The keycaps can be removed for cleaning or replacement. Use a keycap puller (not included) to gently pull keycaps straight up. Be careful not to damage the switches.
- Cable Care: Handle the coiled Type-C cable with care. Avoid sharp bends or excessive pulling, especially at the connectors, to prevent damage.
- Storage: When not in use, store the keyboard in a clean, dry environment away from extreme temperatures and direct sunlight.

Troubleshooting
If you encounter issues with your ZIYOU LANG K3 keyboard, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Keyboard not responding | Loose cable connection, incorrect USB port, driver issue. | Ensure the Type-C and USB-A ends of the cable are securely connected. Try a different USB port on your computer. Restart your computer. |
| Backlight not working or stuck | Backlight turned off, specific mode selected. | Press Fn + INS repeatedly to cycle through backlight modes and ensure it's not off. |
| Keys not registering or double-typing | Dust/debris under keycap, faulty switch. | Remove the keycap and use compressed air to clean the switch area. If the issue persists, the switch may need replacement (requires technical expertise). |
