Note the following regarding
YPAO measurement
• Test tones are output at high
volume and may surprise or
frighten small children.
• Test tone volume cannot be
adjusted.
• Keep the room as quiet as
possible.
• Stay in a corner of the room
behind the listening position
so that you do not become an
obstacle between speakers
and the YPAO microphone.
• Do not connect headphones.
