Care of Your Cassette Tape Player A tape player that is not cleaned regularly can cause reduced sound quality, ruined cassettes aor 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 failure of 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 this message appears on the display, your cassette tape player needs to be cleaned. It will still play tapes, but you should clean it as soon as possible to prevent damage to your tapes and player. If you notice a reduction in sound quality, try a known good cassette to see if it is the tape or the tape player atfault. If this other cassette has no improvement in sound quality, clean the tape player. The recommended cleaning method for your cassette tape player is the use of 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 dealership(GM P a r t No. 12344789). When using a scrubbing action, non-abrasive cleaning cassette, it is normal for the cassette to eject because your unit is equipped with a cut tape detection feature and a cleaning cassettemay appear asa broken tape. To prevent the cleaning cassette from being ejected, use the following steps. If your vehicle is equipped with the AM-FM Stereo with Cassette Tape Player: 1. Turn the ignition to RUN or ACCESSORY. 2.
