The C3D pedometer is programmed to reset all step counts at midnight, so you wake up the next morning and start at zero again.
However, if you intentionally reverse the AM/PM setting on your clock, this resetting function could be triggered at noon instead. Allowing you to have a full night of step counts without interruption.
First you will need to decide whether you want the clock to display a traditional 12Hr format showing 1PM or the world clock 24Hr format of 13:00 instead of 1PM.
Follow the directions on how to Set the Clock.
