Audio System Theft Protection On EX and EX-V6 models Your car's audio system will disable itself if it is disconnected from electrical power for any reason. To make it work again, the user must enter a specific code using the preset bars or the TUNE knob. Because there are hundreds of number combinations possible, making the system work without knowing the exact code is nearly impossible. You should have received a card that lists your audio system's code number and serial number. It is best to store this card in a safe place at home. In addition, you should write the audio system's serial number in this Owner's Manual. If you should happen to lose the card, you must obtain the code number from your Honda dealer. To do this, you will need the system's serial number. If your car's battery is disconnected or goes dead, or the radio fuse is removed, the audio system will disable itself. If this happens, you will see in the frequency display the next time you turn on the system. Use the preset buttons to enter the code. If your car is equipped with a navigation system, press and release the TUNE knob; the number ''0'' appears on the display. If ''0'' is the first digit in your code, press and release the TUNE knob to store it. If ''0'' is not the first digit in your code, turn the TUNE knob left or right until the first digit is displayed. Press and release the TUNE knob to store it. Enter the remaining digits the same way. When all the digits in the code are entered correctly, the radio will start playing. If you make a mistake entering the code, do not start over or try to correct your mistake. Complete the sequence, then enter the correct code. You have ten tries to enter the correct code. If you are unsuccessful in ten attempts, you must then leave the system on for one hour before trying again. You will have to store your favorite stations on each side of the preset bars (1 6) after the system begins working. Your original settings were lost when power was disconnected.
