4. Maintenance

4.1 Battery Care

  • The Rii i4 uses a rechargeable 700mAh Lithium-ion battery.
  • To prolong battery life, avoid fully discharging the battery frequently.

  • The battery is replaceable (BL-5C type).

4.2 Cleaning and Storage

  • Use a soft, dry cloth to clean the keyboard and touchpad.
  • Avoid using harsh chemicals or abrasive materials.
  • Keep the device away from liquids and extreme temperatures.
  • When not in use, store the USB receiver in its dedicated compartment on the back of the keyboard to prevent loss.

5. Troubleshooting

  • Keyboard not responding: Ensure the keyboard is charged and powered on. Check the connection mode (2.4G or Bluetooth) matches your device. For 2.4G, ensure the USB receiver is properly inserted. For Bluetooth, ensure it's paired correctly.
  • Touchpad not working: There might be a shortcut key to enable/disable the touchpad. If accidentally deactivated, try pressing various FN key combinations or refer to the full user manual for specific touchpad toggle keys.
  • Backlight not working: Ensure the keyboard is powered on. Press FN + the backlight button (usually a light bulb icon) to activate or adjust brightness.
