WARNING
A loud tone (noise) may be emitted from the
speakers when measuring the vehicle’s acous-
tics. Never perform the Auto EQ measurement
while driving.
CAUTION
! Thoroughly check the conditions before per-
forming Auto EQ, as the speakers may beda-
maged if this is performed under the following
conditions:
— When the speakers are incorrectly con-
nected. (For example, 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 capabil-
ity.
! If the microphone for acoustical measure-
ment (sold separately) is not placed in an ap-
propriate 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 pos-
sible, with the vehicle engine and air condi-
tioning switched off. Also, cut power to car
phones or cellular phones in the vehicle, or
remove them from the vehicle before per-
forming Auto EQ. Sounds other than the
measurement tone (surrounding sounds,
engine sound, telephones ringing, etc.)
may prevent correct measurement of the
vehicle’s acoustics.
