Care of Your Cassette Player and Tapes 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 failure of 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 see if the to tape or tape player is at fault. If the second cassetteresults in no improvement in sound quality, try cleaning the tape player. Proper tape player cleaningshould be done with a scrubbing action, non-abrasive cleaning cassette.This is 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. To properly clean your tape player, follow instructions with the cleaning cassette. If you use this type of cleaner, the radio may display an error and ejectthe cartridge. This is normal and is the result of an added feature in 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. 3-27
