Using Environment and Precautions
The device should be stored in a soft case, and the operating environment should be at a temperature of -5~40℃, and the relative humidity should not exceed 80%.
The device should be stored in a clean and dry place to avoid moisture, mold, heavy pressure, mechanical damage,humidity and direct sunlight.
Avoid using in the rain or fog, avoid dropping or shocking.
When the screen on the LCD does not light up, it indicates that the voltage is too low, and it needs to be charged in time.
