If there is a reduction in sound quality, try a known good cassette to see if the tape or the tape player is at fault. If this other cassette has no improvement in sound quality, clean the tape player. For best results, use a scrubbing action, non-abrasive cleaning cassette with pads which scrub the tape head as the hubs of the cleaner cassette turn. The recommended cleaning cassette is available through your dealer. When cleaning the cassette tape player with the recommended non-abrasive cleaning cassette, it is possible that the cassette may eject, because the cut tape detection feature on the radio may recognize it as a broken tape, in error. To prevent the cleaning cassette from being ejected, use the following steps: 1. Turn the ignition on. 2. Turn the radio off. 3. Press and hold the TAPE DISC button for five seconds. READY will appear on the display and the cassette symbol will flash for five seconds. 4. Insert the scrubbing action cleaning cassette. 5. Eject the cleaning cassette after the manufacturer's recommended cleaning time. When the cleaning cassette has been ejected, the cut tape detection feature will be active again. A non-scrubbing action, wet-type cleaner which uses a cassette with a fabric belt to clean the tape head can be used. This type of cleaning cassette will not eject on its own. A non-scrubbing action cleaner may not clean as thoroughly as the scrubbing type cleaner. The use of a non-scrubbing action, dry-type cleaning cassette is not recommended. After the player is cleaned, press and hold the eject button for five seconds to reset the CLEAN indicator. The radio will display --- or CLEANED to show the indicator was reset. Cassettes are subject to wear and the sound quality may degrade over time. Always make sure the cassette tape is in good condition before the tape player is serviced. Care of Your CDs and DVDs Handle CDs carefully. Store them in their original cases or other protective cases and away from direct sunlight and dust. The CD player scans the bottom surface of the disc. If the surface of a CD is damaged, such as cracked, broken, or scratched, the CD will not play properly or not at all. If the surface of a CD is soiled, take a soft, lint free cloth or dampen a clean, soft cloth in a mild, neutral detergent solution mixed with water, and clean it. Make sure the wiping process starts from the center to the edge. 3-129
