4.9 About GPS Search

The watch automatically activates GPS positioning when entering the workout preparation page for outdoor sports such as running, and notifies you once positioning is successfully activated. Also, GPS positioning automatically deactivates when you quit the workout preparation page or complete the workout.
GPS search remains active for six minutes. You will be prompted to reposition yourself if the positioning attempt times out and fails. If you remain inactive for 20 minutes after successful positioning, the watch automatically turns off positioning to save power. In such cases, you must reposition yourself before proceeding with the workout.

Positioning suggestions:
Use GPS positioning in open outdoor areas, and wait until the positioning is successful before beginning any workouts. If you are in a crowd, raise your arm to your chest to accelerate positioning.

Auxiliary GPS (AGPS):
AGPS is a kind of GPS satellite orbit information data which helps the watch accelerate GPS positioning.
When the watch remains connected with the mobile phone through Bluetooth, the watch regularly synchronizes and updates AGPS data to the Amazfit Watch app on a daily basis. AGPS data expires if the watch has not synchronized data with the Amazfit App for seven days. If this happens, positioning efficiency can be compromised, and you will be promoted to update your data through system messages.

5. Physical Indicators for the Workout

The watch provides a rich variety of physical indicators for workouts, and you can use evaluation scores as a reference for your workouts. These indicators are determined based on your profile and other data such as heart rate. As the watch continues to understand and analyze your body and workout data, the accuracy of evaluation scores gradually improves.

5.1 Maximum Oxygen Uptake (VO2max)
Maximum oxygen uptake refers to the amount of oxygen consumed by the body during maximum-intensity workouts, which is an important indicator of the body’s aerobic capacity. As one of the most important references for endurance athletes, high maximum oxygen uptake is the prerequisite for high aerobic capacity.
Maximum oxygen uptake is a relatively personal indicator, which has different reference standards for different genders and age groups. The watch evaluates your athletic ability based on your profile and the heart rate and speed during your workouts. Also, maximum oxygen uptake changes with your athletic ability. However, everyone has a maximum oxygen uptake limit, which varies by individual.

How do I retrieve maximum oxygen uptake?

① Correctly enter your profile in the Amazfit App.

② Run outdoors for at least 10 minutes while wearing the watch and ensure that your heart rate reaches 75% of your maximum heart rate. ③ After the running ends, you can view your current maximum oxygen uptake in the watch’s workout record app or on the Amazfit
App>>Workouts>>See more Statuses.

④ Maximum oxygen uptake scores map to seven athletic ability levels:

How do I view maximum oxygen uptake?

You can view the current maximum oxygen uptake in the watch’s workout status app.

You can also view the same data and its variation trends in the Amazfit App.

5.2 Training Effect

Training Effect (TE) is an indicator for measuring the effect of a workout on improving aerobic capacity. When you work out while wearing the watch, the TE score starts from 0.0 and increases as the workout progresses. The TE score ranges from 0.0 to 5.0, and different score ranges indicate different effects. A higher TE score indicates a greater workout intensity and a higher body load, but also a better TE. However, you should consider whether your body load is too high when the TE score reaches 5.0.

ideal for post-workout recovery training.
2.0 – 2.9| TE is moderate and helps maintain aerobic capacity.
3.0 – 3.9| TE is good and significantly helps improve aerobic capacity.
4.0 – 4.9| TE is excellent, effectively improving cardio ability and aerobic capacity.
 5. 0| Workout intensity overloads your body, and post-workout recovery is required for non-athlete users.

The TE score is evaluated based on your profile, as well as your heart rate and speed during your workout. A low TE score does not indicate a problem with the workout, but signifies that the workout is easy and has no significant effect on improving aerobic capacity (for example, the TE score is low for one hour of jogging.)

How do I retrieve my TE score?

The watch provides real-time TE scores while running, and the runner can adjust his or her motions based on these scores. Once a workout for which heart rate data is monitored ends, the watch displays the TE score of the workout and provides relevant comments or suggestions. Also, you can review the TE score of each workout record in the future.

5.3 Training Load

The watch calculates training load based on EPOC (Excess Post-Exercise Oxygen Consumption) scores over the past seven days to evaluate your workout quantity. You can adjust your subsequent training schedule based on your training load score range.

Also, you can view training load scores and their variation trends for the last 28 days under Workout>>Personal Status in the Amazfit App.

6. Daily Maintenance

① The watch is water resistant. We recommend cleaning the watch and watchband regularly with water and drying with a soft cloth before wearing.
② Avoid using detergents such as soap, hand sanitizer, or bath foam for cleaning to prevent chemical residues irritating the skin or corroding the device.

Notes

① The watch can withstand pressure equivalent to 50 meters underwater. Therefore, it can be used when swimming in pools and shoals. However, it cannot be used for underwater diving, free underwater diving, diving, surfing, showering, and a sauna.
② Do not operate the watch underwater by touching screen or pressing buttons. If the watch gets wet, do not operate the touch screen or charge the watch until it is wiped clean using a soft cloth.
③ The watch is not resistant to corrosive liquids such as acidic and alkaline solutions and chemical reagents. Damage or defects caused by misuse or improper use are not covered by the warranty.
