Maintenance
Cleaning the Keyboard
- Disconnect the keyboard from your computer before cleaning.
- Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe the keycaps and chassis.

- Avoid using harsh chemicals or abrasive materials, as these can damage the keyboard's finish or keycap legends.
Switch Replacement

Troubleshooting
Keyboard Not Responding
