6. Maintenance

• Cleaning: Use a soft, dry cloth to wipe the keyboard surface. For deeper cleaning, you can use a keycap puller to remove keycaps and clean dust or debris with compressed air.
• Battery Care: To prolong battery life, avoid fully discharging the keyboard frequently. Charge it when the battery is low. If storing for a long period, charge it to about 50% and store in a cool, dry place.
• Switch Replacement: When replacing switches, use a switch puller and ensure the new switch is aligned correctly before pressing it into the hot-swap socket to avoid bending pins.

7. Troubleshooting

• Keyboard not responding:
  • Ensure the keyboard is charged.
  • Check the connection mode switch (2.4G, BT, Wired) is set correctly.
  • For 2.4G, ensure the receiver is properly plugged in and try re-pairing (FN+4).
  • For Bluetooth, ensure it's paired correctly and try re-pairing (long press FN+1/2/3).
  • For wired, ensure the USB-C cable is securely connected to both the keyboard and the computer.
  • Try connecting to a different USB port or device.
• RGB lighting not working or stuck:
  • Ensure the keyboard is powered on.
  • Try adjusting brightness (FN+HOME/END) or changing light modes (FN+INS).
  • Perform a factory reset (FN+ESC).
• Keys not registering or double-typing:
  • This might indicate a faulty switch. Since the keyboard is hot-swappable, you can try replacing the problematic switch.
  • Ensure the switch is fully seated in its socket.

8. User Tips

• Lighting Adjustment: While the multimedia knob can adjust lighting effects, some users find the FN key combinations (FN+INS, FN+DEL, FN+HOME/END, FN+PRTSC/SCRLK) more precise for controlling RGB brightness, color, and speed.
• Cable Management: Note that the USB-C port is located on the left side of the keyboard. Plan your cable routing accordingly, especially if you prefer a center-aligned cable.
• Print Screen Key: The compact layout does not include a dedicated Print Screen key. You may be able to remap this function to another less-used key using third-party software if needed.
• Stability: If the keyboard feels light and slides on your desk, consider using a desk mat to provide better grip and stability.
• Software: The keyboard may have companion software for advanced customization. This software is typically in English.
