CHERRY UTILITY
To control most aspects of the Cherry MX 3.0S Wireless RGB keyboard you will need to download the utility software.
Typically, the software checks for available firmware updates for both the keyboard and the RF dongle and informs you about them as seen above.
The main tab of the utility software allows you to check battery life, set the brightness level and speed and switch between the 11 available effects.
This software also allows you to create macro commands.
From within the device settings tab, you can enable/disable sleep and hibernate modes, change the layout and check for firmware updates (also repair the keyboard in case of a firmware update issue).
