   IV. FAQ about Health/ Sleep Monitor

Q1 What factors can affect the health measurement results?

1. A1 Non-standard wearing can affect the measurement signal, such as the light leakage caused by incomplete fitting.
2. Swing of the arm, slight movement of the watch on your skin, etc., wearing too tight, raising the arm and making a fist, etc. can affect your blood circulation and thus affect the measurement signal.
3. Correct measuring method: lay the arm flat, relax and stay still, and hold the watch against the arm.
   *Note: individual differences such as skin color, hair, tattoos and scars can also affect the measurement signal, despite correct wearing of the watch.

Q2 How can I measure the HR value correctly?

1. A2 Hold the light-emitting part of the watch against the skin (muscle) to ensure that the watch will not shift a lot during your exercise (tighten the watch strap to achieve a comfortable tightness). Excessive or insufficient tightness can affect the measurement results (avoid light leakage and shift of the reflected light).
2. Do not hold the light-emitting part of the watch against the protruding bones (radius and ulna) on the wrist side.or the watch may fail to correctly receive the red light reflected by blood vessels, which will affect the measurement results.
3. To obtain a more accurate HR value, you can enable ” Elevated Heart Rate Measurement” in the App.

Q3 How does the smart watch measure my HR?

A3 The watch uses the photoelectric transmission method to measure HR: the sensor in contact with the skin will emit a beam of light on the skin, and the reflected/transmitted light will be measured. Blood absorbs the light of a certain wavelength; each time the heart pumps blood, such light will be absorbed in large quantities, based on which, the heartbeat can be determined. The HR measurement 1s based on Photo-Plethysmo-Graphy (PPG), so the measurement accuracy and consistency is associated with “gender, age, BMI, weather, race or skin color, and health or V02 Max”.
The wrist sweat or other impurities, dark skin (which can’t absorb light well), weather conditions and humidity can affect the measurement results.

Q4 Why does the back of the watch automatically glow green?

1. A4 Design philosophy: the light transmittance of the blood is changed by the pulse, and then converted into electrical signals by simple light reflection, which will be recorded; our blood is red and can absorb the green light to the maximum extent; the final data after reflection is the most accurate, so we use green LED as the HR measurement tool.
2. lf you enable automatic HR monitoring, your HR will be measured automatically. You can also enable manual HR measurement. During the measurement, the HR LED will automatically flash and emit green light.

Q5 When does sleep monitoring work?

1. A5 Open Scientific Sleep in the APP, wear it for at least 3 hours from 0:00 to 7am at night, and the data will be synchronized to the APP. There will be no monitoring during the day (blood oxygen is monitored at night, from 0:00 to 7am at night)
2. HRV is the heart health index during sleep
3. What time does sleep time start and end?
   A. Without scientific sleep, wear it from 8 pm to about 10 o’clock the next day.
   B. With scientific sleep on, wear it for at least 3 hours from O pm to 7am.

Q6 How does the smart watch measure my sleep?

A6 Sleep monitoring is performed through the built-in sensor. The sensor can detect the subtle movements of your hand so as to determine whether your body is in an active state or a quiet sleep state. During your sleep, the watch will record the frequency of your hand movements and analyze whether you are in a deep sleep or light sleep state, so as to analyze your sleep quality and provide suggestions.

Q7 What is the meaning of Deep Sleep ,Light Sleep, Waking Sleep and REM Sleep?

1. A 7 Deep sleep, light sleep, waking sleep and REM sleep are determined based on the changes of the sensor level detected during your sleep.

2. If the detected sensor level remains high for a long time, probably you are not sleeping. If the high sensor level is maintained for a short time, it can be filtered out and your sleep quality can be analyzed.

3. The sensor can obtain your corresponding sleep data based on your body movements. It is in contact with your wrist and can detect your body movements. The watch will determine your sleep state based on the frequency of your body movements.
   Frequent body movements indicate light sleep. There are relatively few body movements during deep sleep.

4. REM (rapid eye movement) sleep is a stage of sleep during which your eyeballs move rapidly and involuntarily. At this stage, the activity of neurons in your brain is the same as when you’re awake. Most vivid dreams that can be recalled subsequently occur during REM sleep. This is the lightest stage of sleep.

FAQ about Step Counting

Q1 How does the watch count my steps?

A1 The watch uses a three-axis acceleration sensor to track the number of your steps. The three-dimensional acceleration data captured by the sensor in real time will be processed through filtering and peak-valley detection, and finally will be converted into readable values (steps, distance, calories) in the App using various algorithms and scientific and rigorous logical operations. The shaking and displacement of your hand can be detected by the built-in relatively high-precision acceleration sensor. The displacement of the watch in space can be detected by the integrating accelerometer so as to determine whether new steps are generated.

FAQ about Battery/Charging

Q1 How can I charge the watch?
