3. Maintenance

3.1 Cleaning the Keyboard

• Disconnect the keyboard from your computer before cleaning.
• Use a soft, lint-free cloth lightly dampened with water or a mild cleaning solution to wipe down the keycaps and frame.
• For dust and debris between keys, use compressed air.
• To clean under the keycaps, use the provided keycap puller to carefully remove keycaps. Clean the exposed switches and plate, then reattach keycaps, ensuring they are pressed down firmly.

3.2 Replacing Switches

If a switch becomes faulty or you wish to change switch types:

1. Use the keycap puller to gently remove the keycap from the desired switch.
2. Use a switch puller (not included, but often bundled with custom switches) to carefully grip the top and bottom clips of the switch and pull it straight up from the PCB.
3. Align the pins of the new 3-pin switch with the holes on the PCB.
4. Gently press the new switch into place until it clicks securely. Ensure the pins are not bent.
5. Reattach the keycap.

4. Troubleshooting

4.1 Keyboard Not Responding

• Check Cable Connection: Ensure the USB Type-C cable is securely connected to both the keyboard and the computer. Try a different USB port on your computer.
• Restart Computer: A simple system restart can often resolve connectivity issues.
• Test on Another Device: Connect the keyboard to another computer or compatible device to determine if the issue is with the keyboard or the original computer.

4.2 Backlighting Not Working or Incorrect

• Check Brightness Settings: Ensure the backlight brightness is not set to the lowest level or turned off via keyboard shortcuts (e.g., Fn + arrow keys or other designated keys).
• Cycle Effects: Try cycling through different RGB effects to see if the backlighting responds.

4.3 Specific Keys Not Registering

• Clean Key/Switch: Remove the keycap and inspect the switch for any debris. Use compressed air to clean around the switch.
• Replace Switch: If cleaning does not resolve the issue, the switch itself may be faulty. Replace it with one of the spare switches provided or a new compatible 3-pin switch.
