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 mobile 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.
! When this navigation system is connected
to a power amp with an LPF (low pass fil-
ter), turn the LPF off before performing
Auto EQ. Also, set the cut-off frequency for
the built-in LPF of an active subwoofer to
the highest frequency.
! The distance has been calculated by com-
puter to provide optimum delay to ensure
accurate results. Do not change this value.
— The reflected sound within the vehicle is
strong and delays occur.
— The LPF on active subwoofers or exter-
nal amps delay the lower sounds.
! If an error occurs during measurement, a
message appears and measurement is
cancelled. Check the following before mea-
suring the vehicle's acoustics.
— Front speakers (left/right)
— Rear speakers (left/right)
— Noise
— Microphone for acoustical measure-
ment (sold separately)
— Low battery
