Operating the Keyboard

Maintenance
Proper maintenance ensures the longevity and performance of your keyboard:
- Cleaning: Regularly clean the keyboard surface with a soft, dry cloth. For deeper cleaning, use compressed air to remove dust and debris from between the keycaps. Avoid using harsh chemicals or abrasive materials.
- Keycap Maintenance: The GX Blue Clicky switches are compatible with standard Cherry MX keycaps, allowing for easy replacement or customization. When removing keycaps, use a keycap puller to avoid damaging the switches.
- Cable Management: Utilize the cable management spaces under the keyboard to keep your desk tidy and prevent cable damage.

Troubleshooting
If you encounter issues with your keyboard, try the following solutions:
- Keyboard Not Responding:
- Ensure both USB cables are securely plugged into your computer.
- Try plugging the keyboard into different USB ports.
- Restart your computer.
- RGB Lighting Issues:
- Verify that the Logitech G Hub software is installed and running.
- Check lighting settings within G Hub to ensure a profile is active and not set to off.
- Ensure the lighting toggle (FN + F key combination) is not disabling the lights.
- USB Passthrough Not Working:
- Confirm that the secondary USB cable from the keyboard is connected to your computer.
- Ensure your computer has enough available USB ports and power to support the passthrough.
- Loud Keystrokes: The GX Blue Clicky switches are designed to be tactile and audible. If you desire a quieter experience, consider installing O-rings (not included) on the keycaps to dampen the sound.
- No Number Lock/Scroll Lock Indicators: Please note that this model does not feature dedicated LED indicators for Number Lock or Scroll Lock. This is by design.
