During the software update process, a black screen is displayed on the Kiox 300. What does this mean?
A software update notice is displayed on the Kiox 300 when the software is updated on the eBike system. Once it's the Kiox 300's turn to update itself, only a black screen can be displayed. Please wait until the update of the Kiox software is finished. This may take some time. After that, a screen will appear again on the Kiox 300. During the entire software update process, the Kiox 300 must not be removed from the mount and the eBike must not be ridden.
You can find the Kiox 300 owner's manual here.
