Performing auto EQ
1 Stop the car in a place that is quiet,
close all the doors, windows and sun roof,
and then turn the engine off.
If the engine is left running, engine noise may
prevent correct auto EQ.
2 Fix the optional microphone in the cen-
ter of the headrest of the driver's seat, fa-
cing forward.
The auto EQ may differ depending on where
you place the microphone. If desired, place
the microphone on the front passenger seat to
carry out auto EQ.
3 Turn the ignition switch to ON or ACC.
If the car's air conditioner or heater is turned
on, turn it off. Noise from the fan in the air
conditioner or heater may prevent correct auto
EQ.
