4. The low temperature mode needs to be installed via OTA update. It is turned off by default andneeds to be enabled in the watch settings. After being enabled, whenever the temperature of thewatch surface is lower than -10°C, the watch automatically enters low temperature mode, and onlylimited functions can be engaged at this time. Due to the physical characteristics of lithiumbatteries, the endurance of watches in low temperature environments will be affected to a certainextent. The battery life while in ultra-low temperature environments may vary according to thesettings, operation conditions and other factors, so the actual result may differ from thelaboratory data.
Ultra-low temperature operation with GPS on (-10­°C to -30­°C): Wear the watch all day with a staticwatch face as the watch enters ultra-low temperature mode; raise wrist to see watch time 100 times;150 pushed messages a day; bright screen operation for 5 minutes per day; turn on GPS movement (dualfrequency, all satellites).
Ultra-low temperature operation with GPS off (-10­°C to -30­°C): Wear the watch all day with astatic watch face as the watch enters ultra-low temperature mode; raise wrist to see watch time 100times; 150 pushed messages a day; bright screen operation for 5 minutes per day.

5. Indoor positioning services are not supported. Positioning speed and accuracy may be affected bythe surrounding environment. The watch can automatically connect to up to two satellite systems at atime, and specific satellite connections may depend on your location.

6. These features will be added via OTA update.

7. The shown straight line back to the start of a journey may not be a practical route to follow dueto environmental factors; this is only intended to help you keep track of your position in relationto the start point of the journey. This feature will be added via OTA update. Navigation functionsare compatible with these 18 sports modes: Outdoor running, Walking, Outdoor cycling, Climbing,Hiking, Cross-country skiing, Mountain biking, BMX, Outdoor boating, Bobsleigh and tobogganing,Sledding, Ski orienteering, Biathlon, Race walking, Snowshoeing, Trail running, Orienteering, Openwater swimming.

8. Smart recognition of strength training exercises will be added via OTA update, and will include:Bodyweight squats, Bodyweight straight arm front squats, Barbell squats, Tricep pushdowns, Bent overrows, Barbell bench press, Sit-up holds, Knee-touch sit-ups, Dumbbell flys, Burpees, Burpee jumps,Overhead tricep extensions, Lying tricep extensions, Lateral raises, Jumping jacks. If an exerciseis not auto-recognized by watch, the Zepp App can provide a list of muscle groups or exercise namesto choose from.

9. Training templates and interval training templates will be added via OTA update, and willinclude: Outdoor running, Treadmill, Outdoor cycling, Indoor cycling, Pool swimming, Rope skipping,Rowing machine, Indoor fitness, Core training, Strength training and Stair climbing. Trainingtemplates need to be created on the Zepp App, and up to 40 templates can be stored at a time;interval training can be set directly on the watch.

10. Track Run mode and Smart Trajectory Correction only support 200 meter and 400 meter runningtrack lengths.

11. 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 workoutduration or frequent changes in posture may not trigger the automatic recognition feature. When youare driving a car or taking a bus, or taking part in other such activities, accidental recognitionmay be triggered if these activities are particularly similar to the selected workout mode. When youare conducting outdoor activities, if the GPS signal is poor or the AGPS data information has notbeen synchronized with the mobile phone for an extended period, these outdoor activities may beassessed as indoor activities.

12. According to the ISO 22810:2010 standard, the Amazfit T-Rex 2 achieves a rating of 10 ATM, for awater-resistance of up to 100 meters, and is therefore suitable for splashes, snow, showering,swimming, or some high-speed water sports. It has passed third-party testing conducted by SWQC, andthe report number is SWT2204-36. Remove the watch when taking a hot shower or trip to the sauna,since too much steam can affect the seal and make it less water-resistant in future. Do not wear thewatch with a leather or metal strap when swimming - when preparing to swim, change to afluoroelastomer strap or other suitable type.

13. 24-hour monitoring of heart rate and blood-oxygen saturation (SpO²) needto be enabled in the Zepp App. For heart rate monitoring, the user must enable Auto Heart RateMonitor in the Zepp App, and the minimum value can be set to 1 minute. Abnormal heart rate alertsand the preset value need to be set in the Zepp App. To measure blood-oxygen saturation (SpO²), please wear the watch tightly at one finger-width from the wrist, andkeep your arm still for best results. SpO² alerts are sent if the detectedrate is too low compared to the preset value, which needs to be set in the Zepp App, at a minimum of80%. Movement, and environmental and physical characteristics can affect speed and accuracy ofmonitoring and measurement. The 24-hour stress level monitoring needs to be enabled on the watch orin the Zepp App. Alerts for high stress levels are based on the preset value, and prompts for thebreathing exercise need to be enabled on the watch.
