WARNING
A loud tone (noise) may be emitted from the speakers when
measuring the vehicle's acoustics. Never perform Auto EQ
measurement while driving.
CAUTION
 Thoroughly check the conditions before performing Auto
EQ, as the speakers may be damaged if this is performed
under the following conditions:
— When the speakers are incorrectly connected. (For exam-
ple, when a rear speaker is connected as a subwoofer
output.)
— When a speaker is connected to a power amp delivering
output higher than the speaker's maximum input power
capability.
 If a microphone for acoustical measurement (sold
separately) is not placed in an appropriate location, the
measurement tone may become loud and measurement
may take a long time, resulting in battery drainage. Be sure
to place the microphone in the specified location.
Before operating the Auto EQ
function
 Perform Auto EQ in as quiet a place as possible, with the
vehicle engine and air conditioning switched off. Also, cut
