The Amazfit T-Rex Ultra (model A2142) is a robust smartwatch designed for an active lifestyle, offering a comprehensive suite of features for health monitoring, fitness tracking, and outdoor adventures. This device is built to withstand challenging environments while providing users with essential data and convenient functionalities.
The core function of the Amazfit T-Rex Ultra is to serve as a personal health and fitness companion, providing scientific sleep and workout guidance, alongside personalized health services. It integrates various sensors to monitor key physiological metrics and track physical activity. The watch allows users to monitor their heart rate, blood oxygen saturation, and track various workout types. It also provides basic smartwatch functionalities such as displaying the time, notifications, and other relevant information through its touch screen. The device is designed to be paired with the Zepp app, which acts as a central hub for data analysis, settings customization, and accessing additional features.
The Amazfit T-Rex Ultra is equipped with a touch screen and several physical buttons for intuitive navigation and control. The "Power/Select button" allows users to turn the watch on/off and make selections, while the "Upper button" and "Lower button" provide additional navigation and function access. A dedicated "Back button" simplifies returning to previous screens.
To begin using the watch, it must first be paired with the Zepp app on a mobile phone. The app, available on Google Play Store and Apple App Store, facilitates the initial setup, account registration, and subsequent synchronization of data. Once paired, the watch displays the correct time and allows users to customize various features. For optimal performance and access to the latest functionalities, it is recommended to use the most recent version of the Zepp app and ensure the mobile device runs on Android 7.0, iOS 12.0, or above.
Wearing the watch correctly is crucial for accurate data collection. For heart rate, blood oxygen, and other measurements, the watch should be worn at a distance of at least one finger away from the carpal, with the strap adjusted for a comfortable snugness. During workouts, the watch should be worn tightly enough to prevent movement, ensuring more accurate heart rate data. After exercise, the strap can be loosened for comfort. When measuring blood oxygen saturation, the watch should be worn correctly on the wrist joint, with the arm flat, and a comfortable (appropriately tight) fitting between the watch and the skin. The arm should remain still throughout the measurement process. External factors such as arm sag, arm sway, arm hair, or tattoos can affect measurement results, potentially leading to inaccuracy or no output.
The Amazfit T-Rex Ultra supports a "low temperature mode" which enables its use in environments ranging from -30°C to -10°C. In this mode, certain features and the touch screen may be limited. The watch automatically switches between low temperature mode and normal mode based on the ambient temperature. Users can also manually exit low temperature mode by pressing and holding the back button.
For diving activities, the device is suitable for recreational free diving, with a maximum depth of 30 meters. It is not intended for professional diving or scuba diving. Users engaging in free diving activities should be accompanied by a coach or experienced diving companion and should have received professional training, including breath holding training and testing. It is important to be aware that the electronic device may malfunction, and users should carry a backup device as needed. Before diving, users should ensure their physical condition is suitable and consult a doctor if they have any concerns. To prevent decompression sickness, sufficient surface intervals between scuba diving and free diving are necessary.
Proper charging of the Amazfit T-Rex Ultra is essential for its longevity. The watch is charged using a dedicated charging cable connected to a power adapter or a computer's USB port. The watch should be placed into the charging base, ensuring the metal contacts on the back of the watch align closely with the charging base. The charging progress is displayed on the watch screen. It is critical to use only the charging cable provided with the product and to ensure the charging base is dry before charging to prevent abnormalities or damage. A 1A or above power adapter is recommended for charging.
The device is equipped with a built-in battery that cannot be removed or replaced by the user. Disassembly or modification of the battery is not permitted. Improper disposal of the battery, exposure to fire or hot ovens, mechanical crushing or cutting, or leaving it in extremely high temperatures can lead to an explosion or leakage of flammable liquid or gas. Similarly, exposure to extremely low air pressure can also result in an explosion or leakage.
To maintain the device's performance and appearance, certain care practices should be followed. Avoid using detergents such as soap, hand sanitizer, bath foam, or lotion for cleaning, as these can leave chemical residues that irritate the skin, corrode the device, or degrade its water resistance. The leather strap is not waterproof, so avoid getting it wet, as this can shorten its service life. When using light-colored watch straps, avoid contact with dark clothing to prevent staining. The watch should not be worn during snorkeling, hot showers, hot springs, saunas (steam rooms), diving, underwater diving, water skiing, and other activities involving high-speed water currents. Prolonged exposure to direct sunlight or excessively high or low ambient temperatures should be avoided, as this can cause device failure.
During transportation, the device should be handled with care, kept dry, and away from humidity. The watch should not be worn during MRI examinations or in other highly magnetic environments, as this can cause damage.
For troubleshooting or further assistance, users can refer to the FAQ section on the official support website. If the product is not in use for an extended period, it is recommended to recharge the battery every 6 months to 100% to prevent battery damage due to over-discharge.
The Amazfit Limited Warranty covers manufacturing defects for 12 months from the original purchase date, or another specified period as required by applicable consumer laws. This warranty is in addition to any rights provided by applicable consumer laws.
