To replace switches, use the provided keycap/switch puller. Gently remove the keycap, then carefully pull out the switch. Insert the new switch, ensuring the pins align with the socket holes, and press firmly until it clicks into place. Reattach the keycap.

3. General Cleaning

Regularly clean your keyboard to prevent dust and debris buildup. Use a soft brush or compressed air to remove particles from between the keys. For surface cleaning, a microfiber cloth lightly dampened with water is recommended.

Troubleshooting

  • Keyboard not responding: Ensure the keyboard is charged. Check the connection mode (wired, 2.4G, or BT) and ensure it matches your device's setting. For 2.4G, try re-plugging the USB receiver. For Bluetooth, try re-pairing the device.
  • Keys not registering or double-typing: This could indicate a faulty switch or debris under the keycap. Try cleaning the area or replacing the switch if necessary.
  • RGB lighting issues: Ensure the keyboard is not in a low-power mode. Try cycling through RGB modes using the knob or software. If issues persist, refer to the Redragon support website for firmware updates.
  • Wireless connection unstable: Ensure the keyboard is within range of your device and there are no major obstructions. Avoid interference from other wireless devices.
