Troubleshooting
- Q: Why does the device not boot or start up properly?
- A: Please charge your new device for at least 10 minutes or more before the first usage. This ensures normal device boot and optimal operation. For devices with removable batteries, ensure they are properly installed before charging.
- Q: Cannot find device when pairing?
- A: Please ensure the distance between your phone and the device is less than 0.5m. Also, make sure the device is not under low battery. If there is still a problem after 1.5 hours of charging, please contact customer support.
- Q: Cannot connect the device with the app?
- A: Some smartphone Bluetooth services may become abnormal when rebooted. Please reboot your smartphone before attempting to pair the device again.
- Q: Why does the pedometer not count steps when I have already started walking?
- A: To reduce errors, smartwatches usually set an initial value (e.g., 10 steps). It will start counting steps and display them once you have walked more than this initial value. The app will show the real walking steps and start counting from step 10.
- Q: How to measure blood pressure?
- A: After connecting the phone to the app, switch to the blood pressure page on the watch. Keep this page unchanged for about 10 seconds, and the blood pressure data will appear. While the watch can monitor your heart rate and blood pressure, it cannot be used for any medical purpose. It is only to help people live a healthier life. All measurement results are for reference only and are based on scientific algorithms and sensors. Please do not compare them to medical devices.
