WARNING A loud tone (noise) may be emitted from the speakers when measuring the vehicle's acoustics. Never perform the Auto EQ measurement while driving. CAUTION ! Thoroughly check the conditions before per- forming Auto EQ, as the speakers may be damaged 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 capability. ! If the microphone for acoustical measurement (sold separately) is not placed in an appropriate 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 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. 184 En
