5.2 Note for Mac Users
If you intend to use the keyboard with a Mac system, you must perform the initial key programming on a Windows computer. Once configured on Windows, the settings will be saved to the keyboard's internal memory, allowing it to function with your Mac without needing the software or further configuration on the Mac itself. A USB-C cable connection is always required for operation.
5.3 RGB Lighting Customization
The programming software also allows you to customize the RGB backlighting. You can choose from 7 different colors and select between 2 lighting modes: a gradient effect or a light that activates upon key press. The lighting can also be turned off if preferred.
5.4 Hot-Swappable Keys
The keyboard features hot-swappable sockets, allowing you to easily change the mechanical switches and keycaps without soldering. This provides flexibility to customize the tactile feel and appearance of your keyboard.

- Dust Removal: Use compressed air to remove dust and debris from between the keycaps.
- Avoid Liquids: Do not expose the keyboard to excessive moisture or spill liquids on it, as it is not waterproof.
