Ambient condition 

1. Ambient temperature:≤+40°C, daily temperature≤+35°C, lowest temperature≥-5°C

2.Relative humidity at highest temperature +40,≤50% allowed max relative humidity at low temperature

example for +20 is 90%, it will occur moderate moist due to temperature change

3.Altitude:≤2000m

4.The device is suitable for transportation and storge as following temperatuare:-25°C to 55°C. The device should not be suffer from non recovery damage
