Cleaning the cabinet Clean the cabinet, panel and controls with a soft cloth slightly moistened with mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as thinner, benzine or alcohol. To save a tape permanently To prevent a tape from being accidentally recorded over, break off the cassette tab from side A or B as illustrated. Break off the cassette tab If you later want to reuse the tape for recording, cover the broken tab with adhesive tape. Before placing a cassette in the tape deck Take up any slack in the tape. Otherwise, the tape may get entangled in the parts of the tape deck and become damaged. When using a tape longer than 90 minutes The tape is very elastic. Do not change the tape operations such as play, stop, and fast-winding frequently. The tape may get entangled in the tape deck. Cleaning the tape heads Clean the tape heads after every 10 hours of use. Be sure to clean the tape heads before you start an important recording or after playing an old tape. Use a separately sold dry-type or wet-type cleaning cassette. For details, refer to the instructions of the cleaning cassette. Demagnetizing the tape heads Demagnetize the tape heads and the metal parts that have contact with the tape after every 20 to 30 hours of use with a separately sold demagnetizing cassette. For details, refer to the instructions of the demagnetizing cassette.
