Theft-Deterrent Feature THEFTLOCK® is designed to discourage theft of your vehicle's radio. It works by using a secret code to disable all radio functions whenever battery power is interrupted. If THEFTLOCK® is active, the THEFTLOCK® indicator will flash when the ignition is off. The THEFTLOCK® feature for the radio may be used or ignored. If ignored, the radio plays normally and the radio is not protected by the feature. If THEFTLOCK® is activated, the radio will not operate if stolen. When THEFTLOCK® is activated, LOC will appear on the radio display to indicate a locked condition anytime battery power has been interrupted. If the battery loses power for any reason, you must unlock the radio with the secret code before it will operate. If you allow more than 15 seconds to elapse between any steps, the radio automatically reverts to time and you must start the procedure over at Step 4. 1. Write down any three or four-digit number from 000 to 1999 and keep it in a safe place separate from the vehicle. 2. Turn the ignition on. 3. Turn the radio off. 4.
