You don't. As the user manual states on page 7:
"The System Status Category does not contain any configurable settings, but does provide important information regarding your monitor’s serial number, firmware version, & current configuration."
The system status menu is a useful overview of current monitor settings, but you don't change anything from here. One quick example: The system status menu lists the current volume level as one of many current system settings, but you don't change the audio from that menu. We make it much simpler by actually having a dedicated volume knob that you can adjust up/down or press to to instantly mute.
