Maintenance
How to clean the connectors
Frequent detachment will deteriorate the
connectors.To minimize this possibility,
ENGLISH
periodically wipe the connectors with a cotton
swab or cloth moistened with alcohol, being
careful not to damage the connectors.
Connector
Moisture condensation
Moisture may condense on the lens inside the
CD player in the following cases:
• After starting the heater in the car.
• If it becomes very humid inside the car.
Should this occur, the CD player may
malfunction.In this case, eject the disc and leave
the unit turned on for a few hours until the
moisture evaporates.
To play new discs
New discs may have some rough
spots around the inner and outer
edges. If such a disc is used, this
unit may reject the disc.
To remove these rough spots, rub the edges
with a pencil or ball-point pen, etc.
To keep discs clean
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.
• Do not use any solvent (for example,
conventional record cleaner, spray, thinner,
benzine, etc.) to clean discs.
Do not use the following discs:
Warped disc
How to handle discs
When removing a disc from
its case, press down the center
holder of the case and lift the disc
out, holding it by the edges.
• Always hold the disc by the
edges. Do not touch its recording surface.
When storing a disc into its case, gently insert
the disc around the center holder (with the
printed surface facing up).
• Make sure to store discs into the cases after
use.

More about this unit
Basic operations
Turning on the power
• By pressing SOURCE on the unit, you can
also turn on the power. If the source is ready,
playback also starts.
Turning off the power
• If you turn off the power while listening to a
disc, disc play will start from where playback
has been stopped previously, next time you
turn on the power.
Selecting the sources
• When no disc is loaded in the unit, “DISC”
cannot be selected.
Tuner operations
Storing stations in memory
• During SSM search...
– All previously stored stations are erased and
stations are stored newly.
–
Received stations are preset in No. 1 (lowest
frequency) to No. 6 (highest frequency).
– When SSM is over, the station stored in
No. 1 will be automatically tuned in.
• When storing a station manually, a previously
preset station is erased when a new station is
stored in the same preset number.
Disc operations
Caution for DualDisc playback
• The Non-DVD side of a “DualDisc” does
not comply with the “Compact Disc Digital
Audio” standard. Therefore, the use of NonDVD side of a DualDisc on this product may
not be recommended.
General
• This unit has been designed to reproduce
CDs, and CD-Rs (Recordable)/CD-RWs
(Rewritable) in audio CD (CD-DA) format.
• When a disc has been loaded, selecting
“DISC” for the playback source starts disc
play.
Inserting a disc
• When a disc is inserted upside down, the disc
automatically ejects.
• Do not insert 8 cm discs (single CD) and
unusual shape discs (heart, flower, etc.) into
the loading slot.
Playing a CD-R or CD-RW
• Use only “finalized” CD-Rs or CD-RWs.
• This unit can play back multi-session discs;
however, unclosed sessions will be skipped
while playing.
• Some CD-Rs or CD-RWs may not play
back on this unit because of their disc
characteristics, and for the following causes:
– Discs are dirty or scratched.
– Moisture condensation occurs on the lens
inside the unit.
– The pickup lens inside the unit is dirty.
– CD-R/CD-RW on which the files are
written with “Packet Write” method.
– There are improper recording conditions
(missing data, etc.) or media conditions
(stain, scratch, warp, etc.).
• CD-RWs may require a longer readout time
since the reflectance of CD-RWs is lower than
that of regular CDs.
• Do not use the following CD-Rs or CD-RWs:
– Discs with stickers, labels, or protective seal
stuck to the surface.
– Discs on which labels can be directly
printed by an ink jet printer.
Using these discs under high temperatures
or high humidity may cause malfunctions or
damages to the unit.
Changing the source
• If you change the source, playback also stops
(without ejecting the disc).
Next time you select “DISC” for the playback
source, disc play starts from where it has been
stopped previously.
