Maintenance
Cleaning Your Keyboard
To ensure longevity and optimal performance, regular cleaning is recommended:
- Disconnect the keyboard from your computer before cleaning.
- Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe down the keycaps and frame.
- For deeper cleaning, you can remove keycaps using the provided keycap puller and use compressed air to clear debris from underneath.
- Avoid using harsh chemicals or abrasive materials that could damage the keyboard's finish or keycap legends.
Troubleshooting
1. Keyboard Not Responding
- Ensure the keyboard is charged.
- For wired connection, try a different USB port or cable.
- For Bluetooth, ensure the keyboard is in pairing mode or connected to the correct device slot (FN+E/R/T). Try re-pairing the device.
- Check if the power switch on the back of the keyboard is in the 'ON' position.
2. RGB Lights Not Working or Incorrectly Displaying
- Ensure the keyboard is powered on.
- Cycle through lighting modes using FN + \|.
- Adjust brightness using FN + [ { and FN + ] }.

3. Keys Not Registering or Double-Typing
- Remove the keycap and switch for the affected key. Re-insert the switch firmly to ensure proper contact.
- Test with a different switch if available, as the switch itself might be faulty.
- Ensure the keyboard firmware is up to date (check surmen's official website for updates).
4. Incorrect Key Mapping (e.g., Alt and Windows keys swapped)
- Refer to the keyboard's software (if available) for remapping options.
