Chapter 32 Customizing preferences 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 power to car phones or cellular phones in the vehicle, or remove them from the vehicle before performing 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 microphone for acoustical measurement (sold separately). Using another microphone 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 not be able to be performed 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, 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 computer to provide the 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 external amps delay the lower sounds. ! If an error occurs during measurement, a message appears and measurement is canceled. Check the following before measuring the vehicle's acoustics. - Front speakers (left/right) - Rear speakers (left/right) - Noise - Microphone for acoustical measurement (sold separately) - Low battery Performing Auto EQ p Auto EQ changes the audio settings as follows: !
