9. Troubleshooting
- Keyboard not pairing / Blue LED flashing: Follow the manual pairing steps in Section 4.2. Ensure the USB receiver is securely plugged into your device.
- Cannot change keyboard language (e.g., stuck on English): For Android TV boxes (like mibox4s), you may need to install a specific keyboard layout application or adjust language settings within your device's operating system. Some users report success with Shift + Alt after installing an app.
- Keyboard not working with iPhone/Smartphone: This keyboard is generally not compatible with iPhones or standard smartphones. It is designed for devices with a USB port for the 2.4GHz receiver.

- Lost or broken USB receiver: If your USB receiver is lost or broken, please contact Rii customer support for assistance with obtaining a replacement.
10. User Tips
- Battery Life: To extend battery life, especially during long usage sessions, consider turning off the LED backlight when not needed.
- Gaming Compatibility: While suitable for many applications, some devices (e.g., miboxS) may not recognize the keyboard as a gamepad, which could affect compatibility with certain games. Verify device-specific gaming support if this is a primary use case.
11. Maintenance
- Cleaning: Use a soft, dry cloth to clean the keyboard surface. For stubborn dirt, a slightly damp cloth can be used, ensuring no moisture enters the device.
- Storage: Store the keyboard in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: Avoid fully discharging the battery frequently. Charge the keyboard regularly to maintain battery health.
