NOTICE: Before you add any sound equipment to your vehicle a -like tape player, CB radio, mobile telephone or two-way radio be sure you can add what you want. If you can, it's very important to do it properly. Added sound equipment may interfere with the operation of your vehicle's engine, Delco@ radio or other systems, and even damage them. And, your vehicle's systems may interfere with the operation of sound equipment that has been added improperly. So, before adding sound equipment, check with your dealer and be sure to check Federal rules covering mobile radio and telephone units. Care of Your Cassette Player and Tape A tape player that is not cleaned regularly is subject to reduced sound quality, ruining the cassette, or damaging the mechanism. Tape cassettes that are not properly stored in their plastic cases away from contaminants, direct sunlight, and extreme heat, may not operate properly and could cause premature failureof the tape player. Your tape player should be cleaned with every 50 hours of use to provide optimum performance. Your radio may display "Cln" (Clean) to indicate that you have used your tape player for 50 hours without re-setting the tape clean timer. If you notice a reduction in sound quality, regardless of when the tape player was last cleaned, try playing a different cassette to see if the tape or tape player is at fault. If the second cassette results in no improvement in sound quality, try cleaning the tape player. Proper tape player cleaning should be done with a scrubbing action, non-abrasive cleaning cassette. Thisis a wet-type cleaning system that uses a cleaning cassette with pads which scrub the tape head as the hubs of the cleaner cassette turn. properly clean your tape player, follow instructions To with the cleaning cassette. If you use this type of cleaner, the radio may display an error and eject the cartridge. Thisis normal and is the result of an added featurein the tape player that detects broken tapes. If an error occurs, you will need to insert the cleaning cassette at least 3 times to thoroughly clean the tape player. You may prefer to use a non-scrubbing action, wet-type cleaner. This type of cleaner uses a fabric belt to clean the tape head. This type of cleaner cassette will not cause an error, but it may not clean the tape player as thoroughly as the scrubbing type cleaner. 3-18
