particular room as shown in the following table and will be higher than
the noise specification, which was measured in an echo-free room.

If nothing appears even after the batteries are replaced, make sure
that the batteries are installed in the correct directions (+, –).
The self diagnosis function has operated to protect the air conditioner.
Turn off the power switch immediately and consult your dealer. Be
sure to provide the dealer with the model name.
When another indoor unit is operating in heating mode, the control
valve opens and closes occasionally to maintain stability in the air
conditioning system. This operation will stop after a while.
* If this will cause an undesirable rise in the room temperature in
small rooms, etc., stop the operation of the indoor unit temporarily.
