USING YOUR SWITCH
Before the AutoUpdate begins, a warning screen will be displayed, informing the user of the risks involved in proceeding with the update, and actions that should be avoided while the update is in progress.
Note: It is crucial that the PC and the Switch remain powered-on, and the USB cable remains connected to the PC or the Switch during the update. The user should also avoid using the PC in ways that might interfere with the operations of the AutoUpdate application. If the update process is disturbed, the Switch could become nonfunctional. If the update is interrupted, but the Switch is still on, you should be able to restart the update (you may have to restart the AutoUpdate application).
