How do I view my previous Diary entries?

From the Home screen in the FCV Sentinel app, click the "Go to Diary" button. In the resulting screen, press the "Review Previous Entries" button. You'll next see the list of previous diary entry titles chronologically listed in the resulting screen. Simply press on the diary entry you'd like to view, and it will take you to a screen showing that diary entry. Once you've finished, simply click the "<" button in the upper-left of the screen to back out.
