3.Ambient humidity
When installing screen, ambient relative humidity should be in the range from 30% to 70%.It is prone to get static electricity when
the indoor humidity is below 30%; when the indoor humidity is higher than 70%, electronic components are easy to get damp.
4.Corrosive gas environment
Please do not install the display in corrosive gas environment containing acid or base components, such as chemical warehouse.
5. Electromagnetic radiation environment
Please do not install display when electromagnetic radiation and radio frequency radiation environment is over field strength 5V/m.

Screens are placed in the environment of low dust as far as possible, otherwise it will affect the display effects, as well as damage
the circuit.If exposed to water for various reasons, please immediately power down until the screen unit dry.
