5. Maintenance
5.1 Cleaning the Keyboard
The keyboard features an IP6X dustproof mainboard, making it resistant to dust and spills. However, the interface is not waterproof.
- General Cleaning: Use a soft, dry cloth to wipe down the keycaps and frame.
- Deep Cleaning: For stubborn dirt or spills, you can carefully remove the keycaps using the provided keycap puller. Clean the keycaps with a mild soap solution and allow them to dry completely before reattaching. Use compressed air to clear debris from under the keycaps.
- Water Exposure: While the mainboard is waterproof, avoid submerging the keyboard or exposing the USB-C port to liquids. If liquid spills occur, disconnect the keyboard immediately and allow it to dry thoroughly before reconnecting.


6. Troubleshooting
- Keyboard Not Responding:
- Ensure the USB-C cable is securely connected to both the keyboard and your computer.
- Try connecting the keyboard to a different USB port on your computer.
- Test the keyboard on another computer if possible to rule out a computer-specific issue.
- Keys Not Registering / Double Typing:
- This could indicate a faulty switch. Since the switches are hot-swappable, try replacing the problematic switch with a new one.
- Ensure the switch is properly seated in the PCB.
- RGB Lighting Not Working / Incorrect Colors:
- Check the keyboard's software for lighting settings and ensure they are configured correctly.
- Try resetting the keyboard's lighting profiles through the software.
- Ensure the keyboard's firmware is up to date.
- Programmable Functions Not Working:
- Ensure the driver software is installed and running.
- Verify that you are in the correct programmable layer (Fn+W, Fn+E, or Fn+R).
- Check macro definitions and key assignments within the software.
- Keyboard Detected as 'GK' vs 'SK':
- GK (Mechanical Switch): PCB uses physical trigger. Power saving, but slower trigger.
- SK (Optical Switch): PCB uses optical principle for triggering. Faster trigger, but consumes more power.
- Ensure you have the correct model (GK or SK) and corresponding software/drivers if applicable.
