General information about the Delco Loc II radio
1. Some audio systems installed on the vehicles described in this manual are equipped with a Delco Loc II code radio. In such a system, the owner can set (program) a secret code that will automatically block the operation of the radio when the battery power is interrupted (withdrawal), making it inoperable.
2. Before performing any operation that requires disconnecting the battery or removing the radio, make sure you remember the code. This code must be entered after connecting the battery.
3. The radio can also be unlocked before disconnecting the power by entering a code. After that, the display will immediately show and then the current time will be displayed.
4. If you do not know the code of your radio or you have difficulty unlocking the radio, please contact the service department.
