a battery icon will show the low-battery status on the display.)
Note: The battery should be fully charged before first use.
XXVIII. Precautions
1. The rated voltage of the product is 5V. Please charge the device promptly when the battery is
low so that the service life of the thermal imager will not reduce due to battery over-discharge;
2. Using this product in a high-temperature environment for a long time is not recommended.A
too high temperature will cause the thermal imager to enter the high-temperature protection
status and shut down automatically;
3. The recommended temperature for using this product is -10°to +50°.A temperature
exceeding this range will affect the service life of the product;
4. Before using this product in an environment with water, ensure that the Type-C interface
rubber cap on the bottom of the thermal imager is tightly covered;
5. Do not aim the thermal imager at radiation sources such as the sunlight and laser in any
circumstance, to avoid irreversible damage to the thermal imager;
6. In the calibration mode, the thermal imager will reduce the automatic shutter correction
frequency. If the image is degraded, cover the lens cover for manual background calibration;
7. If the thermal imager is not used for a long time, recharge the device every 2 months at least,
and store the device in a dry and ventilated environment.
8. When you configure the thermal imager with a laser pointer, do not aim the laser pointer at
human eyes.
9. The laser and cursor functions are subject to the laws in different countries or regions;
10. Do not charge the device in an environment with a temperature over 40°C.
