6. Maintenance
6.1 Cleaning
To clean your keyboard, first disconnect it from your computer. Use a soft, dry cloth to wipe down the keycaps and chassis. For deeper cleaning, you may use the included keycap puller to remove keycaps and clean underneath with compressed air or a small brush. Ensure the keyboard is completely dry before reconnecting.
6.2 Switch Replacement
The GALAX Stealth-03 / STL-03 features hot-swappable mechanical switches. If a switch becomes faulty or if you wish to change the typing feel, you can replace individual switches. Use the included switch puller to carefully remove the desired switch. Align the pins of a new switch (e.g., one of the included Black switches) with the holes on the PCB and gently press it into place until it clicks. Ensure the switch is seated correctly to avoid bending the pins.
7. Troubleshooting
- Keyboard not responding: Ensure the USB cable is securely connected to both the keyboard and the computer. Try a different USB port or restart your computer.
- Keys not registering: If specific keys are not working, try removing and re-seating the keycap. If the issue persists, the switch may be faulty. Utilize the hot-swappable feature to replace the switch with a spare one.
- Lighting issues: Ensure the keyboard is properly powered. Cycle through lighting modes using FN key combinations. Adjust brightness with FN + Arrow keys.
- Windows key locked: Press FN + Windows key to toggle the Windows key lock function.
