Maintenance
7Care of lens
Storage
When the lens in the pick-up gets dirty, malfunctions including the impos-
sibility of playback may occur. The lens should be cleaned using a commer-
cially available camera lens blower, etc. Do not touch the lens to prevent
damaging the mechanism. Also do not use a lens cleaner or disc cleaner
product.
When a disc is not to be played for a long period of time, remove it from the
CD player and store it in its case.
7Caution on condensation
Condensation (of dew) may occur inside the unit when there is a great
difference in temperature between this unit and the outside.
This unit may not function properly if condensation occurs. In this case,
leave the unit for a few hours and restart the operation after the conden-
sation has dried up.
7Care of main unit
When the unit gets dirty, clean with a soft, dry cloth. If the unit is stained
seriously, a moistened cloth can be used. Do not use thinner, benzine,
alcohol, etc. for these agents may cause discoloration.
Be specially cautious against condensation in the following circumstances:
When this unit is carried from one place to another across a large difference
in temperature, when the humidity in the room where this unit is installed
increases, etc.
7Cleaning the plug
Wipe the headphone plug with a soft cloth to keep it clean.
A dirty plug may cause noise or malfunction.
7Caution on disc used
Usable discs:
This unit is capable of playing back the Audio CD discs, CD-R/CD-RW (CD-
DA, MP3/WMA) discs and discs carrying the
marking. Other discs
cannot be played. 8 cm single CDs can be played as they are; do not use a
commercially-available single CD adapter.
÷ Certain CD-R/CD-RW (CD-DA, MP3/WMA) discs may not be played
due to recording conditions of the discs.
Handling:
Hold compact discs so that you do not touch the playing surface.
Do not attach paper or tape to either the playing side or the label side of
compact discs.
Never play a cracked or warped disc:
During playback, the disc rotates at high speed in the player. Therefore, to
avoid danger, never use a cracked or deformed disc or a disc repaired with
tape or adhesive agent.
Cleaning
If fingerprints or foreign matter become attached
to the disc, lightly wipe the disc with a soft cotton
cloth (or similar) from the center of the disc
outwards in a radial manner.
