Having trouble?
Here is the solution. (Unit is operating normally.)
Noise is louder than specifications.
The indoor operation sound level is affected by the acoustics of the
particular room as shown in the following table and will be higher than
the noise specification, which was measured in anechoic room.

faint, or signals are not received by the indoor unit unless the IR wireless
remote controller is close. (*)
The batteries are low.
Replace the batteries and press the Reset button.
If nothing appears even after the batteries are replaced, make sure that
the batteries are installed in the correct directions (+, –).
The operation lamp near the receiver for the IR wireless remote controller
on the indoor unit is blinking. (*)
The self diagnosis function has operated to protect the air conditioner.
Do not attempt to repair this equipment by yourself.
