• Wipe the surface with a microfiber cloth.
• Avoid using harsh chemicals or abrasive materials.

Troubleshooting

Connection Issues

• Wired Connection Not Detected: Try a different USB port or cable. Ensure the cable is fully inserted.

RGB Backlighting Problems

• Lights Not Working: Check if RGB is enabled via function keys or software. Ensure battery is charged.
• Incorrect Effects: Use the knob or software to cycle through and select desired effects.

Keys Not Responding

• Specific Keys: If a single key is not working, the switch might be faulty. Due to hot-swappable design, you can replace the switch.
• Multiple Keys: Check connection mode and battery. If wired, try a different USB port.

Multi-function Knob Issues

• Knob Not Responding: Ensure the keyboard is powered on and connected. Try long-pressing FN to switch its mode.
