iGPSPORT products have passed waterproof testing in accordance with product specifications before shipping.
If you encounter fog during use, it may be caused by the following reason:
iGS520 had a built-in barometric altitude sensor.I
n order to balance the air pressure in the inner and outer cavities of the device and accurately measure the air pressure value, iGS520 needs openings and a waterproof and breathable membrane to achieve the accuracy of the measurement.
When iGS520 encounters high humidity and high temperature or sudden temprerature change, the water vapor in the air will enter the inner cavity of the device through the waterproof and breathable membrane, which will cause short-term fog under the condition of the temperature difference between the inside and outside.
When you find that there is fog in the computer, it is recommended that you put the device to a dry and suitable temperature environment to accelerate the evaporation of water vapor;
