Notes

1. Thanks to the glass cover, the product has no obvious border on the front, bringing a "borderless" visual experience.

2. Always-on Display: When the screen is illuminated, it displays system content. When the screen is in standby mode, it displays the time. This function requires users to manually set "Always-on Display". The user can switch on or off this feature through the watch or app.

3. This product is not a medical device and cannot be used for medical purposes or as basis for diagnosis of any medical condition. Detection results are provided for reference only. Please consult professional medical institutions if you feel unwell.

4. To process the one-tap measurement, please wear the watch tightly at one finger-width from the wrist, and keep your arm still for best results. Movement, and environmental and physical characteristics can affect speed and accuracy of monitoring and measurement.

5. To measure SpO2, please wear the watch tight at one finger-width from the wrist and keep your arm still for best results. All-day monitoring of SpO2 needs to be enabled on the watch or in the Zepp App. SpO2 alerts are sent if the detected rate is too low compared to the preset value, which needs to be set in the Zepp App, at a minimum of 80%. Movement, and environmental and physical characteristics can affect speed and accuracy of monitoring and measurement.

6. The 24-hour heart rate monitoring feature requires the user to enable Auto Heart Rate Monitor in the Zepp App, and the minimum value can be set to 1 minute. Abnormal heart rate alerts and the preset value need to be set in the Zepp App.

7. The HUNT Fitness Study indicates that people who maintain a PAI score of 100 or higher show lower risk of hypertension, heart disease, and type-2 diabetes. HUNT Fitness Study: This study was conducted by Professor Ulrik Wisloff of the Faculty of Medicine, Norwegian University of Science and Technology. It lasted for more than 35 years and had more than 230,000 participants. To use this function, all-day heart rate monitoring must be enabled.

8. Sleep monitoring can record night sleep and naps that last more than 20 minutes. Any sleep period that starts or ends between 10pm-8am will be recorded as night sleep, and if you fall asleep within a 60-minute window at either side of your night sleep period, it will also be recorded as night sleep. Sleep recordings that start or end over 60 minutes outside your night sleep period, and that do not overlap the 10pm-8am timeslot at any point, will be recorded as a nap.

9. The 24-hour stress level monitoring needs to be enabled on the watch or in the Zepp App. Alerts for high stress levels are based on the preset value, and prompts for the breathing exercise need to be enabled on the watch.

10. The accuracy and sensitivity of the workout recognition feature varies from person to person, and are related to the posture and proficiency of the user during their workout. Short workout duration or frequent changes in posture may not trigger the automatic recognition feature. When you are driving a car or taking a bus, or taking part in other such activities, accidental recognition may be triggered if these activities are particularly similar to the selected workout mode. When you are conducting outdoor activities, if the GPS signal is poor or the AGPS data information has not been synchronized with the mobile phone for an extended period, these outdoor activities may be assessed as indoor activities.

11. Swimming Stroke Recognition includes: Freestyle, Breaststroke, Butterfly-stroke, Backstroke, and Medley.

12. Indoor positioning services are not supported. Positioning speed and accuracy may be affected by the surrounding environment.

13. Virtual Pacer is only compatible with Outdoor Running and Treadmill sports modes.

15. To see the full list of 15 countries/regions and 14 languages supported, as well as how to activate and use Alexa on your Amazfit GTS 3, please visit support.amazfit.com.

16. Offline voice assistant only supports English, Spanish and German voice commands.

17. The battery life may vary according to the settings, operation conditions and other factors. So the actual result may differ from the laboratory data.
