Setting Radio Anti-Theft Procedure

Delco Loc II is a security feature which can be used or ignored. If ignored, the radio assembly will play normally. If used, the radio assembly will be useless if stolen because it won't turn on.

This is how to enter a secret code into the radio assembly. If battery power is lost for any reason, the secret code must be entered again before the radio assembly will turn on.

1. Write down any 6-digit number and keep in safe place.
2. Turn ignition to "ACCESSORY" or "RUN" position.
3. Turn the volume control knob to the left to turn radio assembly off.
4. Press buttons "1" and "4".together and hold until "---" shows on display.
5. Do not wait more than 15 seconds between each step.
6. Press "SET" and "000" appears on the display.
7. Press "SCAN" and hold until first digit of code appears.
8. Press "SEEK < or >" to make second and third digits appear.
9. Press the lower knob (tune knob) ("000" appears).
10. Press "SCAN" and hold until fourth digit of code appears.
11. Press "SEEK < or >" to make last two digits of code appear.
12. Press the lower knob (tune knob) ("rEP" appears for 5 seconds, then "000" appears).
13. For verification, repeat steps 7 through 11. Next, press the lower knob (tune knob). "SEC" will then be seen on display, meaning radio assembly is secured. If the display shows "---", the verification steps were not successful and the entire sequence must be repeated from step 6.
