5. Troubleshooting
5.1. Connection Issues
- Keyboard not connecting (Wired/2.4G/Bluetooth): Ensure the keyboard is powered on and fully charged. For wired, check the Type-C cable connection. For 2.4G, ensure the receiver is securely plugged in and try a different USB port. For Bluetooth, ensure Bluetooth is enabled on your device and the keyboard is in pairing mode (FN+1/2/3). Try restarting both the keyboard and your device.
- Intermittent connection: Check for interference from other wireless devices. Ensure the keyboard is within range of the receiver/Bluetooth device.
5.2. Lighting Issues
