To change switches or internal modular components, remove keycaps and follow the manufacturer’s instructions for hot-swap replacement and gasket adjustments. Ensure the computer recognizes the device before adjusting advanced settings.

Recommendations

For optimal responsiveness in competitive play, use the Hall Effect performance mode and set a high polling rate if supported by your system. When customizing switches, test different switch types and gasket tensions to find the desired balance of sound and typing feel. Keep keycaps and the keyboard surface clean and avoid spilling liquids to preserve the aluminum finish and electrical components.
