Here is a quick guide on how to set up your Apex M800 keyboard.
1) Plug both USB cables into your computer, starting with the primary USB end. If you have a tower, plug this cable in the primary USB ports in the back of the device. We recommend avoiding using USB ports on top or the front of your case as these usually are hub ports and have a lower power rating. If you have a laptop, please use the USB 3.0 ports where available.
2) Navigate to the SteelSeries GG page and download the latest version of SteelSeries GG. After running the installer, allow the software to update the firmware of your device if needed. Once finished you can customize your key binds, macros, and illumination settings.
