Care of Your Cassette Tape Player A tape player that is not cleaned regularly can cause reduced sound quality, ruined cassettes ora damaged mechanism. Cassette tapes should be stored in their cases away from contaminants, direct sunlight and extreme heat. If they aren't, they may not operate properly or may cause failureof the tape player. Your tape player should be cleaned regularly after every 50 hours of use. Your radio may display CLN to indicate that you have used your tape player for 50 hours without resetting the tape clean timer. If you notice 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. Cleaning may be done with a scrubbing action, non-abrasive cleaning cassettewith pads which scrub the tape head as the hubs of the cleaner cassetteturn. It is normal for the cassette to ejectwhile cleaning. Insert the cassette at least three times to ensure thorough cleaning. A scrubbing action cleaning cassetteis available through your GM dealer. You may also choose a non-scrubbing action, wet-type cleaner which uses a cassette with a fabric belt to clean the tape head. This type of cleaning cassettewill not eject. It may not clean as thoroughly as the scrubbing type cleaner. Cassettes are subject to wear and the sound quality may degrade over time. Always make sure that the cassette tape is in good condition before you have your tape player serviced. 3-27
