Warning 40 The measurement has completed. However, the noise level is high. You may be able to
perform the measurement properly if you try it again, even though the measurement cannot
be performed in all environments. Try to perform the measurement in a quiet environment.
Warning 41 The sound input from the optimizer microphone is outside the acceptable range. It is louder
than the loudest sound that can be measured. Try to perform the measurement when the
environment is quiet enough to allow proper measurement.

when the environment is quiet enough to allow proper measurement.
Warning 43 The distance and position of a sub woofer cannot be detected. Or the angle of the speaker
position cannot be detected. This may be caused by noise. Try to perform the measurement
in a quiet environment.
