Precautions:
1. Make sure to wear it tightly for more than 10 minutes, and measure it at room temperature (about 25℃) in a quiet state;
2. Wipe your wrist to ensure that it is dry and free from water stains, alcohol and other volatile substances;
3. If you are exercising, taking a bath or switching between indoor and outdoor environments, please wait for 30 minutes before measuring;
4. Please avoid measuring in direct sunlight, windy and cold/heat sources;
5. When the wearable device is not worn, the ambient temperature is too low (35℃) to measure the current temperature. Please try again later.
6. In order to ensure the measurement accuracy, please avoid measuring when the body is hot (for example, after charging, in high-power scenes such as Bluetooth listening to songs), and then measure after the body temperature drops steadily.
