Sony MHC-GX20 Operating Instructions - Page 28

Precautions (continued) 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 every 20 to 30 hours of use with a separately sold demagnetizing cassette. For details, refer to the instructions of the demagnetizing cassette.
