6. Maintenance
- Cleaning: Use a soft, dry cloth to wipe the keyboard surface. For deeper cleaning, remove keycaps and use compressed air to clear dust and debris from between switches.
- Storage: Store the keyboard in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery: For wireless modes, ensure the keyboard is charged regularly via the Type-C port. Avoid fully depleting the battery for extended periods.
7. Troubleshooting
- Keyboard not responding: Ensure the keyboard is properly connected (wired) or paired (wireless). Check the mode switch (Type-C/2.4G/Bluetooth) is set correctly. For wireless, ensure the battery is charged.
- 2.4G Wireless connection issues: Ensure the 2.4G receiver is securely plugged into a USB port. Try a different USB port.
- Bluetooth pairing issues: Ensure Bluetooth is enabled on your device and the keyboard is in pairing mode. Remove previous pairings and try re-pairing.
- RGB lighting not working: Check the lighting control key combinations (FN+DEL, FN+PGUP, etc.). Ensure the keyboard is not in a low-power mode.
- Keys not registering: For hot-swappable switches, ensure switches are fully seated in the PCB. If a specific key is not working, try swapping the switch with a known working one to diagnose if the issue is with the switch or the PCB.
- Driver: If advanced customization or specific functions are not working, you may need to install the dedicated driver software. Contact customer service for driver download links.
