    – Lake your measurement at the same time each day to ensure the most accurate results.
    Please place your scale on the hard/flat ground, then step on the scale with bare feet, then the display will be turned on. And the warm tips before using the scale:
    – Check your profile information (gender, age and height), make sure all the data is accurate.
    – Check the place, make sure it is hard/flat, some place seems flat, but actually not, you could try remove different hard surface until it gets the same result
    – Check the legs of the scale before your measure, if it is not balanced, the data won’t be accurate.
    – Make sure that “CAL” and “0.0” shown on the display, before each time use.
    – Keeps bare feet, with each foot touching both the top and bottom electrode.
  2. Why doesn’t the scale work?
    Why does the data on the screen disappear in a flash?

    – Ensure Bluetooth is enabled and working.
    – Ensure personal data is entered.
  4. I saw “Athlete Mode” option when I create my profile, what is it? Should I open it ?
    What is the definition of an Athlete?
    – The general consensus among researchers is that a quantitative dimension could be used to define an athlete. An athlete is defined for this scale as a person who consistently works out for approximately 3 times per week at 2 hours for each occurrence.
    These individuals should select Athlete Mode for the most accurate measurement results.
    Please note that scale is not calibrated for professional athletes or bodybuilders.
  5. Why is the Athlete Mode necessary in a Body Fat Scale?
    – It has been found that body fat estimation using BIA could overestimate the percentage body fat of adult elite athletes. The physiological variation of athletes in bone density and level of hydration are two of the reasons said to account for the difference.
  6. How to restart the scale?
    – First, took one of the batteries out of the scale.
    – Then, put back the batteries and wait for 5 seconds.
    – Now the scale has been automatic restart, you can step onto the scale.
