outdoor unit.

If this field setting is done, the maximum sound level will be 2dB lower than the maximum
sound level during normal night operation (unit without this field setting and with outdoor
unit quiet operation activated). So when this field setting is done on the unit, it is NOT
needed to activate the outdoor unit quiet operation to meet the local regulation.
INFORMATION
New setting may affect the performance of the unit.
