The Quick Check shows first responders particularly important yes/no cues at a glance. Open Medical Profile → Quick Check and activate Quick Check use? with Yes.
After that, the Note before activation message window will appear. Read the note and select Understood, continue. Then answer each point completely and truthfully with Yes or No. Changes will be saved automatically; at the top, Will be saved... and then Saved will appear briefly.
An activated but incompletely completed Quick Check can be misunderstood in an emergency. The wording I hereby confirm that I have carefully weighed each individual point! describes the confirmation for the activation; it is not a permanently visible menu item of its own. If you set Use Quick Check? back to No, the area will not be displayed in the emergency profile.
