Coding Radio

NOTE: A radio code is required to release the radio from lockout (radio will not function). The radio code card is provided to vehicle owner by manufacturer.
  1. Obtain radio code number.
  2. If the radio is disconnected from the power supply, it cannot be operated by simply reconnecting. After switching on the ignition and the radio, the word "CODE" appears in the display on the radio.
  3. Enter the code number with the station button, e.g. number 1, station button 1.

    After entering the first number the word "CODE" disappears and the number entered appears followed by 4 dashes. The next character to be entered flashes. After entering all five numbers, the first character starts flashing again. In this state the code number can be written over as frequently as desired. A correction can be made only by entering the complete code number again.

  4. Confirm code number: Press TUNE, AUTO/SEEK or SC button. The radio automatically switches on and indicates the radio station or frequency stored with station button 1.
  5. If an incorrect code number is entered and confirmed, the word "CODE" appears again on the display. If an incorrect code is entered three times the word "WAIT" appears on the display and the radio locks up for approximately 10 minutes. If the code is entered incorrectly three times again the radio locks up again for 10 minutes. Three more incorrect entries (a total of 9 incorrect attempts) increase the lock-up time to 60 minutes. Another three incorrect entries lock up the radio for another 60 minutes. The waiting time starts only after the radio is switched on.
