- Use compressed air to remove dust and debris from between the switches.
- Wipe keycaps with a soft, damp cloth and mild soap solution if necessary. Ensure they are completely dry before reattaching.
- Do not use harsh chemicals or abrasive materials, as they may damage the keycaps or keyboard finish.
7.2 Switch Replacement
To replace switches:
- Use the provided keycap puller to remove the desired keycap.
- Use the provided switch puller to gently grip the switch and pull it straight up.
- Align the pins of the new 5-pin mechanical switch with the holes on the PCB.
- Press the new switch firmly into place until it clicks. Ensure it is seated correctly and not bent.
- Reattach the keycap.
8. Troubleshooting
- Keyboard not responding: Ensure the keyboard is charged, the correct connection mode (2.4G/USB/BT) is selected, and the OS switch (Mac/Win) is set correctly. For wireless modes, ensure the receiver is properly plugged in or Bluetooth is paired.
- Backlight not working/incorrect: Use FN key combinations (FN+INS, FN+DEL, FN+arrows) to adjust backlight effects, colors, brightness, and speed. Ensure the keyboard is not in a low-power state.
- Keys not registering: If specific keys are not working, try replacing the switch for that key, as the keyboard is hot-swappable. Ensure the switch is fully seated.
- Connectivity issues: For 2.4GHz, try plugging the receiver into a different USB port. For Bluetooth, try re-pairing the device. For wired, ensure the USB-C cable is securely connected and not damaged.
