The EJECT button will work with the radio off. Theft-Deterrent Feature THEFTLOCK@is designed to discourage theft of your radio. It works by using a secret code to disable all radio functions whenever battery power is interrupted. The THEFTLOCK feature for the radio may be used or ignored. If ignored, the system plays normally and the radio is not protected by the feature. If THEFTLOCK is activated, your radio will not operate if stolen. When THEFTLOCK is activated, the radio will display LOC to indicate a locked condition anytime battery power is removed. If your battery loses power for any reason, you must unlock the radio with the secret code before it will operate. Compact Disc Messages E (Error): If this message and a number appears on the radio display or if the disc comes out, it could be for one of the following reasons: You're driving on a very rough road. When the road becomes smoother, the disc should play. It's very hot. When the temperature returns to normal, the disc should play. The disc is dirty, scratched, wet or upside down. The air is very humid. If so, wait about an hour and try again. If the CD is not playing correctly, for any other reason, try a known good CD. Activating the Theft-Deterrent Feature The instructions which follow explain how to enter your secret code to activate the THEFTLOCK system. Read through all nine steps before starting the procedure. 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. If any error occurs repeatedly or if an error can't be corrected, contact your dealer. If your radio displays an error number, write it down and provide it to your dealer when reporting the problem. 3-54
