Measures when the warning mode appears

about 180 seconds.
After the cooling fan stops running, turn off the main power supply switch, and remove the power plug from the outlet.
Perform the following checks and take the corresponding measures.
If the warning indication is displayed again, turn off the main power supply switch after the cooling fan stops running.
Then pull out the power plug from the power outlet. Call your authorized dealer for repair.
