You can change the date and time on your Z1 or Z2 Auto, by connecting it to our Nitelog app on an iPhone/iPad or most Android devices. The app should prompt you to sync to the local date and time upon start up. If it does not, or if you accidentally hit “no” when prompted, swipe left at the main screen (that shows your Z1/Z2 screen) to access the settings menu. You can manually adjust the date and time on this page.
On a Z1 or Z2 CPAP you can change the date and time by using the Dataviewer Software on a Windows computer.
