7. Troubleshooting
| Problem | Possible Solution |
|---|---|
| Keyboard not responding (Wired) | Ensure the USB-C cable is securely connected to both the keyboard and the computer. Try a different USB port or cable. Check the keyboard's mode switch is set to 'Wired'. |
| 2.4G Wireless connection issues | Ensure the 2.4G receiver is plugged in and the keyboard's mode switch is set to '2.4G'. Re-pair by holding 'Fn' + 'R' for 3 seconds. Try a different USB port for the receiver. |
| Bluetooth connection issues | Ensure the keyboard's mode switch is set to 'Bluetooth'. Re-enter pairing mode ('Fn' + '1/2/3' for 3 seconds) and re-pair with your device. Ensure your device's Bluetooth is enabled. |
