Once you receive your pedometer you just need to clip it to your belt or waist band as close to the centre of your body as you can.
The screen will be blank if there is no movement but as soon as you start to walk around the pedometer will start counting and the screen will turn on. The screen will turn off again after one and a half minutes of inactivity but it will not erase the step count.
The button on the pedometer will reset the counter to zero. Only press the button if you want to put the pedometer back to zero.
