5. Troubleshooting
Common Issues and Solutions
- Keyboard not connecting: Ensure the mode switch (Wired/BT/2.4G) is set correctly. For Bluetooth, ensure the keyboard is in pairing mode and visible to your device. For 2.4G, ensure the receiver is properly inserted. Try restarting your computer or the keyboard.
- Keys unresponsive or 'sticky': This could be due to debris under the keycap or a faulty switch. Try cleaning the area or replacing the switch using the hot-swappable feature.
- RGB lighting not working: Check the brightness settings using FN + Arrow Up. Ensure the keyboard is not in a low-power mode. If using software, verify settings there.
- Battery not charging: Ensure the USB Type-C cable is securely connected to both the keyboard and the power source. Try a different cable or USB port.
