5. Maintenance

5.1 Cleaning the Keyboard

To ensure longevity and optimal performance, regular cleaning is recommended:

• Disconnect the keyboard from your device before cleaning.
• Use a can of compressed air to remove dust and debris from between the keycaps.
• For keycap cleaning, gently remove them using the keycap puller. Wash keycaps with mild soap and water, rinse thoroughly, and ensure they are completely dry before reattaching.
• Wipe the keyboard surface with a soft, slightly damp, lint-free cloth. Avoid excessive moisture.

5.2 Keycap and Switch Replacement

As detailed in Section 4.3, the hot-swappable design allows for easy replacement of keycaps and switches. This can be done to customize the keyboard's appearance or to replace worn-out components.

6. Troubleshooting

If you encounter issues with your Surmen GT61 keyboard, refer to the following common solutions:

• Keyboard Not Responding (Wired): Ensure the USB-C cable is securely connected to both the keyboard and the computer. Try a different USB port or cable.
• Keyboard Not Connecting (Bluetooth):
  • Ensure the keyboard's power switch is ON.
  • Make sure the keyboard is in pairing mode (FN + E/R/T, corresponding key flashing).
  • Check your device's Bluetooth settings and ensure Bluetooth is enabled.
  • Forget the device on your computer/phone and try pairing again.
  • Ensure the keyboard battery is charged.
• Incorrect Key Output / Key Mapping Issues: Some users have reported issues with Alt and Windows keys being swapped. This may be a firmware issue or a specific key combination for switching layouts. Consult the manufacturer's support for firmware updates or specific key combinations to resolve this.
• RGB Backlighting Not Working: Ensure the keyboard is powered on. Try cycling through lighting modes using FN key combinations. Check if brightness is set to maximum.
• Keys Not Registering: If a specific key is not working, it might be a faulty switch. Since the keyboard is hot-swappable, try replacing the switch in question with a known working one or one of the extra switches provided. Ensure the switch is fully seated.
• Short Battery Life: Reduce RGB brightness or turn off lighting when not needed. Ensure the keyboard is fully charged before use.
