The THEFTLOCK system is designed in order to discourage theft of the radio. The system uses a secret code in order to disable all radio functions whenever battery power is removed. The THEFTLOCK feature for the radio may be used or ignored. If the feature is ignored, the system plays normally and is not protected by the feature. When THEFTLOCK is activated, the radio displays LOC in order to indicate a locked condition any time battery power is removed. When the battery loses power for any reason, you must unlock the radio with the secret code in order for the radio to operate.

The following instructions explain how to enter the secret code that is needed in order to activate the THEFTLOCK system.

Important: If more than 15 seconds passes between steps, the radio automatically shows the time and you must start over at step 4.

1. Write down any 3-digit or 4-digit number ranging from 000-9999.
2. Turn the ignition to the ACCESSORY or RUN position.
3. Turn the radio off.
4. Press the 1 and 4 buttons together. Hold the buttons down until -- shows on the display.
5. Press MN. The display will show 000.
6. Press MN again in order to make the last 2 digits agree with the code.
7. Press HR in order to make the first 1 or 2 digits agree with your code.
8. Press AM-FM after you have confirmed that the code displayed matches the secret code. The display will show REP and you must repeat steps 5-7 in order to confirm the secret code.
9. Press AM-FM and the display will show SED in order to advise that the radio is secure. The indicator near the volume control will begin flashing when the ignition is turned to the OFF position.
