Care and maintenance

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

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

Compact discs

• Only discs bearing this mark can be used with this system. 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.

Moisture condensation

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.

Cassette tapes

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

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 from a camera store) to blow dust off the lens.

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.

Record/play head

 

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).
