What is a Kcal anyway? The "calorie" we refer to in food is actually kilocalorie. One (1) kilocalorie is the same as one (1) Calorie(upper case C).
If you don't see a person on the left of your screen, the step sensor is paused and won't track your calories burned. See how to activate step sensor.
The setting that helps the SC2 Pedometer provide an estimate of the calories you burn is your weight. See How to set your weight on the SC2.
The SC2 uses the weight setting, the speed and the number of steps taken and the time it took to complete your activity to estimate the number of calories you burned.
* Please note this is only an estimate.
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.
To advance from one screen to the next, press the MODE button.
