Antitheft and Alarm Systems: Description and Operation

Audio Security System Description

The audio security system is activated whenever the audio system circuit is disconnected from the battery. A four-digit security code must be entered in order for the audio system to resume functioning. The security code is stamped on a card located in the vehicle (usually in the glove box). The following security code entering procedure must be used to deactivate the audio security system:
1. After connecting the audio security system to the battery, "CODE" will flash on the display.
2. Enter the proper security number into the unit, using the preset buttons No. 1 through 8.
3. For example, if the security number is "1234":
a. Press the preset button No. 1. "CODE" will disappear and "1 --- " will appear on the display.
b. Press the preset button No. 2, and "12 -- " will appear.
c. Press the preset button No. 3, and "123- " will appear.
d. Press the preset button No. 4, and "1234" will appear and flash three times.

4. The audio system will function and will transfer to the radio. If the incorrect security number is entered into the unit, "Err" will appear followed by "CODE" and there will be several audible beeps. If this happens, repeat the security entering procedure beginning with Step 2.
