How to perform a factory reset on the Ender 3 v3 ke?

How do you perform a complete factory reset on an Ender v3 ke printer? Is there a step-by-step instruction somewhere?

On the control panel you should see a gear icon. Press it and then scroll to the bottom where you will see "Reset factory settings. I’ve not done this (yet) so I’m not exactly sure if it resets it to defaults or what. Hope that helps.
