Need to follow the working steps:-

1. Turn on your display case by pressing the power button at the bottom for 3 seconds

2. Once on, enter your name, time, and date

3. To save and come back to the main screen, swipe right

4. Now, the main screen of the display case will appear, where you can see the time, day, date, battery % of the display case, battery % of the earbuds and a welcome message. 

Note:- Pls check the date/time before swiping right. If the date is incorrect, reset and redo the process. There are chances of false touch because the screen is small; be careful. Don't worry, this is the only time where the keypad is being used.
