Please remove the strip before use else the scales will not switch on. To ensure that your reading is correct, please kindly refer to the following: 1. Clear the scale: step on the scale with one foot until the display lights up, then step off until the scale shows "0.0." Do this each time you are measuring your weight. 2. Scale is placed on a hard, flat surface (tile, wood, etc.). If it is placed on something soft (such as carpet), it will not weigh accurately. 3. Keep your gravity in the center of the scale and your body stable while taking measurements. 4.
