[. . . ] Do not allow liquids or foreign objects to enter the unit. If the unit should become wet, turn off all power and ask your authorized Clarion dealer to clean or service the unit. WIRING PRECAUTIONS Read all wiring precautions. If you are not sure of the connections, contact your authorized Clarion dealer. This unit operates on an automotive 12V negative ground power source and requires additional mobile audio components for proper operation. Disconnect the negative (-) lead of the battery before making any power connections. A good chassis ground connection is critical to the performance of your Clarion equalizer. Use the shortest ground wire possible and securely connect to the car chassis along with the source unit ground to minimize resistance and avoid noise problems. Extra cable can cause signal loss and act as an "antenna" for noise. Use only high-quality RCA cables that are no longer than necessary to make a direct connection with the source unit and amplifiers. 5 5. If you are using a source unit, without a remote turn-on lead, the PEQ460 can be turned on with a switched accessory lead. You can find this accessory power source in the factory harness at the back of the radio. It is the lead that turns on and off with the key. SYSTEM SET-UP Setting System Volume After completing the system wiring, follow the steps below to properly adjust the PEQ460. Turn the master volume control on the PEQ460 and the amplifier gain controls to their minimum setting. Turn the Sub/Lo/Mid/High Frequency controls to the center position. Turn the source unit on and increase the volume until distortion is heard, then reduce volume just below this point. * Once the source unit volume has been set, it will no longer be used. Always use the volume control on the PEQ460 as the master (main) volume control. It has better electronics, higher S/N ratio and is more linear than any source unit volume available. *This is the maximum usable musical signal forthis source unit.
