2. Operating Your Smartwatch

2.1 Smart Features and AI Voice Control

The Amazfit T-Rex 3 Pro integrates advanced smart features, including AI voice control via Zepp Flow AI & GPT-4. To activate and use voice commands:

• Activating Voice Assistant: Ensure Zepp Flow AI is enabled in the Zepp app settings under your device profile. You can typically activate the voice assistant on the watch by swiping right on the watch face or pressing a designated button (refer to your watch's specific button layout).
• Issuing Commands: Once the voice assistant is active, speak clearly to issue commands such as "Start a run," "Check my heart rate," "Set a timer for 10 minutes," or "What's the weather?"

2.2 Health Monitoring with BioTracker 6.0

The BioTracker 6.0 optical sensor provides comprehensive health data. Key metrics include:

• Heart Rate (HR): Continuous heart rate monitoring is active by default. View real-time HR on the watch face or in the Heart Rate app.
• Blood Oxygen Saturation (SpO2): To measure SpO2, ensure the watch is snug on your wrist. Navigate to the SpO2 app on the watch and initiate a measurement. Remain still during the process.
• Sleep Readiness: The watch automatically tracks sleep patterns. Access detailed sleep analysis, including sleep stages and quality scores, in the Zepp app.
• Stress Monitoring: The watch monitors stress levels throughout the day. View your stress trends and receive alerts for high stress in the Zepp app.
• Heart Rate Variability (HRV): HRV data is collected during sleep and specific activities, providing insights into recovery and overall health. This data is accessible in the Zepp app.

For accurate readings, ensure the watch is worn correctly, neither too tight nor too loose, and positioned above the wrist bone.

2.3 GPS Navigation and Outdoor Activities

The T-Rex 3 Pro features dual-band GPS and offline map capabilities for precise outdoor navigation.

• GPS Activation: GPS is automatically activated when starting outdoor workout modes. Ensure you are in an open area for faster satellite acquisition.
• Offline Maps: Download maps for specific regions via the Zepp app before your activity. Once downloaded, these maps can be accessed on the watch for navigation without a phone connection.
• Route Planning and Rerouting: Plan routes in the Zepp app and sync them to your watch. During an activity, the watch can provide real-time navigation and rerouting suggestions if you deviate from the planned path.

2.4 Workout Modes and Performance Tracking

With over 180 sports modes, the T-Rex 3 Pro offers extensive workout tracking.

• Selecting a Workout: Swipe to the "Workout" or "Sports" menu on your watch, then select your desired activity (e.g., Running, Cycling, Swimming).
• Starting a Workout: Tap "Go" or the start icon. For outdoor activities, wait for GPS signal acquisition before starting.
• Real-time Metrics: During a workout, the watch displays real-time data such as duration, distance, pace, heart rate, and calories burned.
• VO2 Max: The watch estimates your VO2 Max (maximal oxygen uptake) during certain outdoor activities, providing an indicator of cardiovascular fitness. This metric is analyzed and displayed in the Zepp app post-workout.
• Post-Workout Analysis: After completing and saving a workout, detailed statistics and performance insights are available on the watch and in the Zepp app.

3. Maintenance and Battery Optimization

3.1 Battery-Saving Tips

To extend the battery life of your Amazfit T-Rex 3 Pro:

• Adjust Screen Brightness: Lower the screen brightness or enable auto-brightness in the watch settings.
• Reduce Screen On Time: Set a shorter screen-on duration in the watch settings.
• Disable Always-On Display (AOD): If not essential, turn off the Always-On Display feature.
• Limit Notifications: Manage app notifications through the Zepp app to only receive essential alerts. Excessive notifications can drain battery.
• Optimize Heart Rate Monitoring: In the Zepp app, adjust the frequency of automatic heart rate monitoring (e.g., from 1-minute intervals to 5 or 10 minutes).
• Turn Off Unused Features: Disable features like Wi-Fi, GPS (when not in use for workouts), or continuous SpO2 monitoring if not required.
• Use Battery Saver Mode: Activate the battery saver mode on your watch when battery is low or when extended usage is needed.

3.2 Cleaning and Care

Regular cleaning ensures optimal performance and longevity:

• Watch Body: Wipe the watch body with a soft, damp, lint-free cloth. Avoid harsh chemicals or abrasive materials.
• Charging Contacts: Periodically clean the charging contacts on the back of the watch and the charging cable with a dry cloth to prevent corrosion and ensure proper charging.
• Strap: Clean the watch strap according to its material. For silicone straps, mild soap and water can be used. Ensure it is completely dry before wearing.
• Water Exposure: While the watch is water-resistant, it is recommended to dry it thoroughly after exposure to water, especially after swimming or showering, to prevent skin irritation and maintain device integrity.
