Cause

detected.
Only right surround back channel signal
is detected.
Measurement cannot be performed
accurately due to loud ambient noise.

The optimizer microphone was
unplugged during the "Auto Setup"
procedure.
The optimizer microphone does not
detect test tones.
The automatic setup procedure was
cancelled due to an inappropriate user

Cause
Speaker polarity is not correct. This
message may appear depending on the
speakers even when the speakers are
connected correctly.
The distance between the speaker and the
listening position is over 24 m (80 ft).
The difference of volume level among
speakers is excessive.
Remedy

If you connect only one surround back speaker,
connect it to the L-side (SINGLE) jack.
Run the automatic setup procedure again during a
time when the environment is quiet.
Turn off noisy electric equipment like air
conditioners or move them away from the optimizer
microphone.
When using surround back speakers, you need to
connect surround L/R speakers.

If a monitor such as a TV is connected to this unit
via HDMI connection, sound may not be output
from this unit due to the HDMI control function. In
such a case, change the monitor setting, for example,
change the sound output setting to an amplifier so
that sound is output from this unit.
Run the automatic setup procedure. Do not adjust the
volume or do other operations during the procedure.
Run the automatic setup procedure again.
Remedy

If they are correct, the speakers work properly even
when this message is displayed.
Bring the speaker within 24 m (80 ft.) area around
the listening position.
Recheck the speaker positions and make sure all
speakers are placed in a similar environment.
