• The Auto Calibration function does not work when 

headphones are connected.

• If the muting function has been activated before 

you perform Auto Calibration, the muting function 
will be set to off automatically.

Place the optimizer microphone at your 
listening position.You can also use a stool 
or tripod so that the optimizer 
microphone remains at the same height as 
your ears.

When you face the speaker towards the optimizer 
microphone, you will get a more accurate 
measurement.

Measurement starts in 5 seconds and the 
display changes as follows:
A.CAL [5] 

t A.CAL [4] t A.CAL [3] 

t A.CAL [2] t A.CAL [1]
While the time is counting down, stand 
away from the measurement area to avoid 
measurement error.
The measurement process will take a few 
minutes to complete.
