Care and maintenance

Handle your discs carefully, and they will last a long time.

Compact discs

• This system can play back the following discs:
– Audio CD
– Finalized CD-R/CD-RW recorded in audio
CD format or MP3 format
However, continued use of irregular shape
discs (heart-shape, octagonal, etc.) can damage
the system.
• Remove the disc from its case by holding it at
the edges while pressing the case's 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 the case.
• Avoid exposure to direct sunlight, temperature
extremes, and moisture.
• A dirty disc may not play correctly. If a disc
does become dirty, wipe it with a soft cloth in a
straight line from center to edge.
CAUTION: Do not use any solvent (for example,
conventional record cleaner, spray thinner,
benzine, etc.) to clean a disc.
General notes
In general, you will have the best performance by keeping your
discs and the mechanism clean.
• Store discs in their cases, and keep them in cabinets or on shelves.
• Keep the disc compartment door closed when not in use.

Cleaning the lens

If the lens in the pickup is dirty, dropout, etc., could degrade sound.
Open the disc compartment door and clean the lens as shown.
• Use a blower (available at camera stores) to blow dust off the
lens.

• If there are fingerprints, etc. on the lens, gently wipe clean with a
cotton swab.

Cassette tapes
Cassette deck
• If the heads, capstans, or pinch-rollers of the cassette deck
become dirty, the following may occur:
– Loss of sound quality
– Discontinuous sound
– Fading
– Incomplete erasure
– Difficulty recording
• Clean the heads, capstans, and pinch-rollers using a cotton swab
moistened with alcohol.
Blower
Lens
• If the heads become magnetized, the system will produce noise or
lose high frequency notes.
• To demagnetize the heads, turn off the system, and use a head
demagnetizer (available at electronics and record shops).
Moisture may condense on the lens inside the
system in the following cases:
• After turning on heating in the room.
• In a damp room.
• If the system is brought directly from a cold to
a warm place.
Should this occur, the system may malfunction.
In this case, leave the system turned on for a few
hours until the moisture evaporates, unplug the
AC power cord, and then plug it in again.
• If the tape is loose, it may get stretched, cut, or
caught in the cassette. Take up the slack by
inserting a pencil in one of the reels and
rotating.
• Do not touch the tape surface.
• Do not store the tape:
– In dusty places
– In direct sunlight or heat
– In moist areas
– On a TV or speaker
– Near a magnet
