In the window that pops up select Satasfaction75, then click “connect” connectdevice

After allowing VIA to connect to the keyboard we can use it to alter the OLED display settings. Click on the “CUSTOM FEATURES” widget in the bottom left of the HUD. OLEDsettings

In custom features you can configure the settings of the Satasfaction75’s OLED screen. “Default OLED Mode” determines which mode will be displayed when the keyboard is turned on. Current OLED Mode determines which mode is currently displayed. There are three modes to choose from:

OLED Mode	Display	Description
Default		Displays BongoCat, clock and WPM (words per minute) tracker
Time		Displays a solitary centered BongoCat
