Battery installation:
This device is supplied with Li-ion 18650 3.7V rechargeable battery *3 pcs.
Please confirm whether batteries + polarity are Li ion18650 positive bump specification and install batteries in
the correct polarity. If the battery polarity is reversed, the capacity will be insufficient and the battery life will be
shortened.
Battery charging:
The charge lamp (○
(5V/1A USB adapter charger)
Note: During battery charging, the temperature of the device will rise by 5°C~10°C. At this time, the
measurements of temperature and humidity will be affected by temperature rise. Cause an impact on
the accuracy of temperature when charging, please use a fan to blow toward the temperature sensor
(○
) directly in order to get a compensated balance of temperature and humidity between temperature
