Subwoofer

Depending on the position of the subwoofer, the 
measurement results for polarity may vary. 
However, there will be no problems even if you 
continue to use the receiver with that value.

Disconnect the optimizer microphone from the 
receiver.

If you have changed the position of the speakers, it 
is recommended you to perform Auto Calibration 
again in order to enjoy the surround sound.

WARN 40

The Auto Calibration has 
completed. However, the noise 
level is high. You may be able to 
perform the Auto Calibration 
properly if you try it again, even 
though the measurement cannot 
be performed in all environments. 
Try to perform the Auto 
Calibration in a quiet 
environment.

WARN 41

The sound input from the 
optimizer microphone is out of 
the acceptable range. It is louder 
than the loudest sound that can be 
measured. Try to perform the 
Auto Calibration when the 
environment is quiet enough to 
allow proper measurement.

WARN 42

The volume of the receiver is out 
of the acceptable range. Try to 
perform the Auto Calibration 
when the environment is quiet 
enough to allow proper 
measurement.

WARN 43

The distance and position of a 
subwoofer cannot be detected. 
This may be caused by noise. Try 
to perform the Auto Calibration 
in a quiet environment.
