AS1: We recommend charging for 2-3 hours with a 5V/1A adapter. To avoid malfunction, do not use an unreasonable charger for charging. After charging, disconnect the charger and charging cable.

AS2: If the product does not charge, it is recommended that the charger be replaced with another charging head.

AS1: “1. What is the defect?

How long has the user been using it?

   When was it discovered?”

AS2: “Communicate with the guest about the current after-sales encountered:

1, defective products do not throw, try to collect up a certain amount, unified to bring back, our factory will be replaced with new treatment:

(1) If it is a problem with the quality of the product, our factory will replace it with a new one for free to the customer;

(2) If it is the user's improper use or external causes of defects, our factory will only charge the actual cost of material loss for a new machine to the customer;

(3) Our factory will not repair the original machine, but only replace it with a new one (for safety reasons);

Based on the above conditions, we hope to help our customers to better handle user feedback and stabilize their links.”

AS3: “Based on the after-sales maintenance data, we need to remind the customer users to pay attention to the following points in the process of using the watch correctly (especially for Japanese users):

1, it is recommended that in the process of use do not wear a long time swimming, diving, soaking, sauna, do not press the buttons when washing hands (the use of the buttons may lead to water seepage), it is not recommended to wear a bath, IP67, is only a waterproof standard, if you do not use the watch correctly, there will be a risk of water ingress.

2, do not use fast charging head for charging (recommended charging conditions: 5V/1A, if you use fast charging head there may be high current will cause the battery to enter the protection, or other loss of function);

3, the watch is subject to extrusion or collision caused by internal damage to the screen (the user wearing the watch, wear can not be too tight; recommended that users wear the watch to leave 1 finger activity space).

4, just press the button normally, don't too vigorously, long time vigorously press the button will cause the button internal can't be normal back to the position; also will make the button short circuit, the button long time in short circuit state cause other function bad (such as display abnormality, charging abnormality, don't turn on the machine, test abnormality and so on).”

AS1: “1: If the social APP message has been opened and viewed on the cell phone/computer, the watch will not remind more (because it is only a message reminder, if it has been viewed, it will not remind more).

2: The watch screen displays up to 3 to 5 information records, the information is real-time push to remind the latest content, the watch pedometer data/auto test data will be automatically cleared in the early hours of the day;

3: Let the customer operate with the following video to see if the permissions are all open (some brands of cell phone permissions will be more complex point need to be opened one by one or is the APP is automatically turned off by the background of the phone).”

AS2: “1: If the social APP information has been opened and viewed on the cell phone/computer, the watch will not be more alert (because it is just an information reminder, if it has been viewed, it will not be more alert).

2: The watch screen displays up to 3 to 5 information records, the information is real-time push to remind the latest content, the watch pedometer data/auto test data will be automatically cleared in the early hours of the day;

3: Let the customer with the following video operation, see whether the permissions are all open (some brands of cell phone permissions will be more complex need to be opened one by one or is the APP by the background of the phone is automatically turned off).”

AS1: Principle of ECG: The special conduction system of the heart consists of the sinus node, the inter-nodal bundle (divided into anterior, middle and posterior inter-nodal bundles), the inter-atrial bundle (starting from the inter-nodal bundle, known as Bachmann's bundle), the inter-atrial junction area (atrioventricular node, Hirschsprung's bundle), the bundle branches (divided into left and right bundle branches, and the left bundle branch is divided into the anterior branch and the posterior branch), as well as the pukinje fibers (Pukinje fibers). The cardiac conduction system is closely related to the electrical changes that occur sequentially during each cardiac cycle. Normal electrical activity begins in the sinoatrial node, excites the atria, and is transmitted to the atrioventricular node via the interjunctional bundle (excitation), and then follows the sequence of the Hirschsprung's bundle - left and right bundle branches - Pukinje fibers, and finally excites the ventricles. This sequential propagation of electrical excitation induces a series of potential changes, which are monitored to form the corresponding bands on the ECG. The electrical changes in different cross-sections of the ECG are usually measured using multiple leads.

AS2: “Uric Acid and Lipids in Blood Composition

Uric acid: Uric acid is the final metabolite of purines in the body, 2/3 of which are metabolized in the kidneys and the remaining 1/3 in the intestine. Uric acid has both antioxidant and anti-inflammatory and pro-oxidant and pro-inflammatory effects, and plays different roles in disease. The low-frequency signal characteristics of uric acid at 530 nm and the ultra-high-frequency signal characteristics at 960 nm have correlation. Using 512Hz ultra-high sampling rate, we can accurately capture the ultra-high-frequency signal characteristics, and synchronize the low-frequency signal characteristics of different wavelengths with the parameters of human height and weight to build a regression model of the characteristics of uric acid; we can optimally output the trend of the user's uric acid changes.

Lipids:Lipids is a general term for neutral fats (triglycerides) and lipids (phospholipids, glycolipids, sterols, steroids) in plasma, which are widely present in the human body. They are essential for the basic metabolism of living cells. Generally speaking, the main components of lipids are triglycerides and cholesterol, of which triglycerides are involved in energy metabolism in the body, while cholesterol is mainly used in the synthesis of cell plasma membrane, steroid hormones and bile acids. By detecting changes in human vascular flow rate, combined with height and weight parameters, specific idiosyncratic ppv-lipid regression models were constructed; the number of models now reaches more than 500; the

AS3: “Body composition

is the proportion of various constituents in the human body, including the distribution of muscle, bone, fat, and other tissues. Using bioelectrical impedance analysis, the percentage of body fat is estimated by sending a weak electric current through the body.”
