"The guarantee remains in effect as long as fixes are conducted using compliance with the user guide plus shall fail to involve non-approved alterations, non-OEM components, or issues to sealed components."

3. Error Logs: Connected units record power drops, reset attempts

 

 

4. Component Serial Numbers: Non-OEM components flagged in database

• Required to show your DIY repair triggered the issue

 

 

• Unable to mandate only their repair and components
