Maintenance
■ Cassette deck head care
To ensure good sound quality for recording and playback, be sure
to clean the heads approximately every 10 hours of use.
1) Turn off the power of the system.
2) Press the eject button to open the cassette holder.
3) Clean the heads, pinch roller, and the capstan shaft with a cotton
swab (or with a soft, lint-free cloth) slightly moistened with iso­
propyl alcohol. Do not use any solution other than alcohol for
head cleaning.
■ Cassette deck head demagnetization
• In order to maintain good sound quality during recording and
playback, we recommend that you demagnetize the head assem­
bly when there is still distortion or poor sound quality after you
have cleaned the heads.
• If the head assembly becomes magnetized, it could create noise
in your recordings, cause a loss of high-frequency response, or
cause the erasure of valuable recordings. There are several types
of head demagnetizers that you can purchase at local electronics
supply stores.
Follow the instructions that are supplied with the demagnetizer.
• Do not touch the head assembly with any type of metal object or
tool such as a magnetic screwdriver.
■ Maintenance of external surfaces
•Use a soft, dry cloth to clean the cabinet and controls.
If the surfaces are extremely dirty, use a soft cloth, dipped in a
soap-and-water solution or a weak detergent solution. Wring the
cloth well before wiping the surfaces. Then wipe once again with a
soft, dry cloth.
• Never use alcohol, paint thinner, benzine, or a chemically treated
cloth to clean the cabinet or controls. Such chemicals may dam­
age the finish of your system.
