Maintenance

To get the best performance of the System, keep your discs,
tapes, and mechanism clean.
Handling discs
• When removing the disc from its case, hold it at the edge while
pressing the center hole lightly.
• Do not touch the shiny surface of the disc, or bend the disc.
• Put the disc back in its case after use to prevent warping.
• Be careful not to scratch the surface of the disc.
• Avoid exposure to direct sunlight, temperature extremes, and
moisture.
To clean the disc:
Wipe the disc with a soft cloth in a straight line from center to
edge.
Handling cassette tapes
• If the tape is loose in its cassette, take up the slack by inserting
a pencil in one of the reels and rotate it.
– If the tape is loose, it may get stretched, cut, or caught in the
cassette.
• Be careful not to touch the tape surface.
• Avoid the following places to store the tape—in dusty places,
in direct sunlight or heat, in moist areas, on a TV or speaker,
or near a magnet.
To keep the best recording and playback sound quality
• Use a cotton swab moistened with alcohol to clean the heads,
capstans, and pinch rollers.
• Use a head demagnetizer (available at electronics and audio
shops) to demagnetize the heads (when the System turned off).
Cleaning the System
• Stains should be wiped off with a soft cloth. If the System is
heavily stained, wipe it with a cloth soaked in water-diluted
neutral detergent and wrung well, then wipe clean with a dry
cloth.
• Since the System may deteriorate in quality, it become
damaged or get its paint peeled off, be careful about the
following:
– DO NOT wipe it with a hard cloth.
– DO NOT wipe it strongly.
– DO NOT wipe it with thinner or benzine.
– DO NOT apply any volatile substance such as insecticides
to it.
– DO NOT allow any rubber or plastic to remain in contact for
a long time.
