Maintenance

To get the best performance of the System, keep your discs,
tapes, and mechanism clean.

Handling discs

• Remove the disc from its case by holding 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 when

placing it back in its case.

• 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, 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 strong.
– 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.
