Troubleshooting

• Keyboard not responding: Ensure the USB Type-C cable is securely connected to both the keyboard and the computer. Try a different USB port or cable.
• Keys not registering: Check if the keycap is properly seated. If it's a hot-swappable switch, ensure the switch is fully inserted into the PCB. If the issue persists, try replacing the switch with one of the extra switches provided.
• RGB lighting not working or incorrect: Ensure the keyboard is properly connected. Use the Fn key combinations (Fn + Esc to reset, Fn + \| for effects, Fn + Enter for colors) to adjust or reset the lighting. If using customization software, ensure it's correctly configured.
• Incorrect layout (Windows/Mac): Use Fn + A for Windows layout or Fn + S for Mac layout to switch between modes.
