Adjusting the equalizer curve
automatically (Auto EQ)
By measuring the vehicle’s acoustics, the
equalizer curve can be adjusted automatically
to suit the vehicle interior.
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 be da-
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 a microphone for acoustical measurement
(sold separately) is not placed in an appropri-
ate location, the measurement tone may be-
come loud and measurement may take a long
time, resulting in battery drainage. Be sure to
place the microphone in the specified loca-
tion.
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.
! Be sure to perform Auto EQ using the mi-
crophone for acoustical measurement
(sold separately). Using another micro-
phone may prevent measurement, or result
in incorrect measurement of the vehicle’s
acoustics.
! To perform Auto EQ, the front speakers
must be connected.
! When this navigation system is connected
to a power amp with input level control,
Auto EQ may be impossible if the power
amp’s input level is set below the standard
level.
