Common problem

Q1: Are the heart rate, blood pressure or other functions accurate?

A1: It is only an assistant for sports and healthy life. The measurement data can only provide reference for sports and healthy life, and cannot be regarded as medical equipment. We recommend that you purchase professional medical equipment when necessary.

Q2: Can I choose more dials on the watch?

A2: Yes, there are multiple fixed dial styles to choose from, you can choose the dial style according to your needs.

Q3: Can I change to other straps?

A3: Yes, if you need more straps, you can contact us, you can choose the straps you need.

Q4: Why does the watch automatically disconnect the Bluetooth connection after the screen of the Android phone is off?

A4:
① Lock the background APP. After the Da Fit process is cleared, it will cause the watch to be disconnected from the phone.
② Set the APP to start automatically.
③ Unlimited background operation. The Android mobile phone installs the APP, the default is to intelligently restrict the background operation, you need to manually set the APP without any restriction measures.

Q5: Why can't the watch receive notifications?

A5:
① Confirm that the message push switch is turned on on the mobile client.
② The confirmation message can be displayed normally in the notification bar of the phone. The watch message push is pushed by reading the message in the notification bar of the phone; if there is no message displayed in the notification bar of the phone, the bracelet will not be able to receive the push. (You need to find the notification settings in the phone settings, and turn on the notification switch of WeChat, QQ, phone, SMS, and mobile client).
③ Open the mobile phone-settings, the top search box, enter “notification of use rights”, and reopen Da Fit.

Q6: Why can't I take a hot bath with my watch?

A6: The temperature of the bath water is relatively high, which will produce a lot of water vapor, and the water vapor is in the gas phase, and its molecular radius is small, and it is easy to penetrate into the gap of the watch case. When the temperature drops, it will condense into a liquid phase again. The water droplets can easily cause the internal circuit of the watch to short circuit, damage the circuit board of the watch, and then damage the watch.

Q7: Why can blood pressure and heart rate be monitored on different objects?

A7: The watch's heart rate and blood pressure monitoring function does not use the traditional “counting pulse” method, but uses an optical measurement method. The main principle is to use light to penetrate the skin tissue and then reflect to the optical sensor. At this time, the light will be attenuated under the flow of blood, and then the sensor will collect these different reflected amounts of light, and then convert it into a digital signal, and finally The heart rate value is output through the algorithm and displayed on the screen.

Warning

Please consult your doctor before starting a new exercise. Although smart watches can monitor real-time ambulatory heart rate and blood pressure, they cannot be used for any medical monitoring purposes. Buyers who use them for medical purposes should purchase with caution, or ask the merchant's customer service.
