is no longer guaranteed. In this case, you have to wait a few hours; After the moisture has dried, the
device can be reused.
Special care should be taken in the following circumstances
When the unit is moved from one place to another at a much higher or lower temperature, or when
the humidity at the installation site increases, etc.
