If the power supply to the radio has been interrupted, "CODE" will appear on the display when it is next switched on. The radio will only work after the five-digit code has been entered using the buttons on the right-hand control panel. The code number is XXXXX on the Radio Code Card, supplied with the radio.

Important! Never leave the RADIO CODE CARD in the vehicle. Keep it in a safe place.

Entering The Code Number

Switch on the radio, "CODE" will appear on the display. Using the buttons on the alpha-numeric keypad, enter the five digit code. Confirm by pressing the "OK" key.
If an incorrect code has been entered and confirmed, "CODE" will reappear on the display. The correct code must be entered once again. If an incorrect code is entered three times, "WAIT" will appear on the display and the radio will be locked out for about 10 minutes.

Note: The lock out time will only count down if the radio is left switched on.
