5. Maintenance

Proper maintenance ensures the longevity and optimal performance of your surmen GT68 keyboard:

• Cleaning Keycaps: Use a soft, damp cloth to wipe down keycaps. For deeper cleaning, remove keycaps with the puller and wash them with mild soap and water, ensuring they are completely dry before reattaching.
• Cleaning the Board: Use compressed air to remove dust and debris from between the keys. A soft brush can also be used.
• Storage: When not in use for extended periods, store the keyboard in a dry, dust-free environment.
• Avoid Liquids: Keep liquids away from the keyboard to prevent damage to internal components.

6. Troubleshooting

If you encounter issues with your surmen GT68 keyboard, try the following solutions:

• Keyboard Not Responding:
  Check the battery level. Ensure the keyboard is powered on and the correct connectivity mode (2.4G, BT, USB) is selected. For wireless modes, ensure the receiver is properly inserted or Bluetooth is paired. Try connecting via USB wired mode to rule out wireless issues.
• Lag or Disconnection in Wireless Mode:
  Ensure the keyboard is within the 10m wireless range. Reduce interference from other wireless devices. Re-pair the Bluetooth connection or re-insert the 2.4GHz receiver.
• RGB Lighting Not Working/Incorrect:
  Ensure the keyboard is powered on. Check FN key combinations for lighting control. If using software, ensure it's correctly installed and configured.
• Specific Keys Not Working:
  If a single key is not responding, it might be a faulty switch. Utilize the hot-swappable feature to replace the switch. Ensure the keycap is properly seated.
• Battery Life Shorter Than Expected:
  High brightness RGB settings consume more power. Reduce brightness or turn off RGB if not needed. Ensure the keyboard is fully charged before use.
