GENERAL DESCRIPTION AND SYSTEM OPERATION

Stereo Cassette AM/FM Radio

There are three audio systems offered. The stereo digital logic cassette AM/FM radio with electronic tape ejection is offered in standard and deluxe models. Both models feature RDS (radio data system) which automatically selects the best station within the chain of RDS stations currently being listened to. A trunk mounted CD changer is also available.

Audio Scurity System

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:

After connecting the audio security system to the battery, "CODE" will flash on the display.
Enter the proper security number into the unit, using the preset buttons No. 1 through 8.
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.

The audio system will function and will transfer to the radio.
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.

Speakers

All audio systems use eight speakers, four speakers and four tweeters mounted in each door.

Tape Player and Cassette Care

The head and the capstan are the two parts of the tape player that should be cleaned. This service should be performed every 100 hours of cassette operation.

To clean the head and the capstan, use a cotton swab dipped in rubbing alcohol.

A cassette cleaning kit may also be used to clean the head and the capstan. Follow the cleaning kit instructions to clean the tape player.

Do not touch the tape head with magnetized tools. If the head becomes magnetized, it will degrade cassettes played in the player. No service is performed on the cassettes. The cassette manufacturer handles warranties of the cassettes. Store cassettes away from extreme heat and direct sunlight.

Compact Disc Care

Handle discs carefully. Store the discs in protective cases away from the sun, heat, and dust. If the surface is soiled, dampen a clean, soft cloth in a solution of mild neutral detergent and wipe the disc clean.
