The multi-functional knob located on the top right of the keyboard provides quick control over various settings:

• Mode Switching: Rotate the knob to switch between work mode (constant RGB glow) and gaming mode (dynamic RGB flashing).

2. NKRO (N-Key Rollover)

The Hi75 supports full N-Key Rollover, meaning every key press is registered independently, regardless of how many keys are pressed simultaneously. This prevents ghosting and ensures accuracy, especially during fast-paced typing or gaming.

3. RGB Lighting

The keyboard features customizable RGB backlighting. Specific key combinations (often involving the FN key and arrow keys or other function keys) can be used to change lighting effects, colors, and brightness. Refer to the quick start guide or software (if available) for detailed RGB customization options.

Maintenance

• Cleaning: Regularly clean your keyboard to prevent dust and debris buildup. Use a soft brush or compressed air to remove particles from between keycaps. For keycap cleaning, remove them using the keycap puller and wipe with a damp cloth.
• Switch Care: If you frequently hot-swap switches, ensure proper alignment to avoid bending pins. Store unused switches in a clean, dry place.
• Cable Management: Avoid sharp bends or excessive tension on the USB-C cable to prolong its lifespan.

Troubleshooting

• Keyboard Not Responding:
  • Ensure the USB-C cable is securely connected to both the keyboard and your computer.
  • Try connecting the keyboard to a different USB port on your computer.
  • Test the keyboard on another computer to rule out system-specific issues.
• Incorrect Key Function (e.g., WIN/ALT keys swapped):
  • This often indicates the keyboard is in the wrong operating system mode. Refer to the "Operating System (OS) Switching" section and use the appropriate FN key combination (e.g., FN+W for Windows, FN+E for Mac) to correct the mode.
• RGB Lighting Not Working/Incorrect:
  • Check the keyboard's current mode using the mode-switching knob. Some modes may have specific lighting behaviors.
  • Ensure the keyboard is properly connected and receiving sufficient power.
  • Consult the quick start guide or software for specific RGB control shortcuts.
