Measurement ends.
“COMPLETE” appears on the display
and the settings are registered.
When you have finished
Disconnect the optimizer microphone from the
AUTO CAL MIC jack.
Notes
• Auto Calibration cannot detect the sub woofer.
Therefore, all sub woofer settings will be
maintained.
• If you have repositioned your speakers, we
recommend that you perform Auto Calibration
again to enjoy the surround sound.
Tips
• When Auto Calibration starts:
– Stand some distance from the speakers and the
listening position to avoid measurement failure.
This is because test signals are output from the
speakers during measurement.
– Avoid making noise to get a more accurate
measurement.
• During the measurement process, the Auto
Calibration function will be canceled when you do
the following:
– Press ?/1 or MUTING.
– Press the input buttons or turn INPUT
SELECTOR on the receiver.
– Change the volume level.
– Connect the headphones.
– Press AUTO CAL again.

Calibration, an error code will appear on the
display cyclically after each measurement
