Click the WHITE button to navigate between screens, until you see a date shown below the line, instead of the clock.

The SC 3D Pedometer comes with a 30 Day memory log. You can scroll back through the dates by pressing the BOTTOM button.

While on this screen, the data will automatically cycle between the different data points every 2 seconds (Step, Mile or KM, Kcal, Min) captured on each day. The BOTTOM button will allow you to change the day being viewed by date. You will notice the date at the bottom of the screen changing dates as you continue to press the BOTTOM button.

The pedometer is designed to have the screen on all the time, it won't use any more power than a digital watch when idle.
