Battery installation:
This device is supplied with Li-ion 18650 3.7V rechargeable batteries (3x), which are pre-installed upon device shipment.
Battery charging:
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. This could cause an effect on the accuracy of
temperature when charging. Please use a fan to blow toward the Temperature & Humidity Sensor (B )
directly, in order to gain a compensated balance of temperature and humidity between that of the
temperature sensor and surrounding area. (5V/1A USB adapter charger).
