CLEAN Indicator Light After 50 hours of cassette tape play, the light will come on as a reminder to clean the tape heads. If the light comes on and the tape heads were not cleaned at the recommended 30 hours of usage (see maintenance section below), they should be cleaned immediately. To reset, push the indicator for a minimum of five seconds until the light goes off. Defective Tape Eject The tape player includes a protection mechanism to automatically eject defective tapes (warped housing, loose label, faulty tape movement) immediately upon insertion. If a tape malfunctions while in play, the tape direction will change back and forth and then eject the cassette. Tapes ejected before play should be considered faulty and discarded; tapes ejected during play may only be unevenly wound and could be re-usable if fully rewound, manually, outside the player. NOTE: The tape player may repeat cycle through the loading and unloading motion several times in an effort to eject a faulty tape. During this process the tape will either eject fully or rise to the loading level and have to be pulled out manually. In either case, discard the tape; re-use may damage the tape player. Maintenance The head in the cassette tape player can pick up dirt or tape deposits each time a cassette is played. The result is low or " m u d d y " sound from one or both channels, as if the treble tone control were turned all the way down. To prevent this, you should periodically clean the head with a commercially available cleaning cassette. As preventive maintenance, clean the head about every 30 hours of use. If you wait until the head becomes very dirty (noticeably poor sound), it may not be possible to remove all deposits with a simple cleaning cassette. The use of 120 minutes tapes is not recommended. CAUTION: Storing cassettes out of their cases, or touching the magnetic tape with your fingers will increase the amount of dirt that gets to the tape head. Using low-quality "offbrand" tape will increase the amount of tape deposits that get on the head. Both of these practices may eventually lead to damage of the head and playing mechanism.
