Handling CDs

This unit has been designed to reproduce CDs,
CD-Rs, CD-RWs and CD Text.
Only for KD-LH7R:
• You can also play back MP3 discs.
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.
To keep discs clean
TE

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.
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.
About mistracking:
w w w
Mistracking may result from driving on extremely
rough roads. This does not damage the unit and
the disc, but will be annoying.
We recommend that you stop disc playback while
.
driving on such rough roads.

Moisture condensation
Moisture may condense on the lens inside the
unit in the following cases:
• After starting the heater in the car.
• If it becomes very humid inside the car.
Should this occur, the unit may malfunction. In
this case, eject the disc and leave the unit turned
on for a few hours until the moisture evaporates.
When playing a CD-R or CD-RW
You can play back your original CD-Rs or CD-RWs
recorded in audio CD format (or in MP3 format: only
for KD-LH7R.) However, they may not be played back
depending on their characteristics or recording
conditions.
• User-edited CD-Rs (Recordable) and CD-RWs
(Rewritable) can be played back only if they are
already "finalized."
• Before playing back CD-Rs or CD-RWs, read
their instructions or cautions carefully.
• Some CD-Rs or CD-RWs may not be played
back on this unit because of their disc
characteristics, damage or stain on them, or if

• CD-Rs or CD-RWs are susceptible to high
temperatures or high humidity; so do not leave
them inside your car.
• CD-RWs may require a longer readout time.
(This is caused by the fact that the reflectance
of CD-RWs is lower than for regular CDs.)
CAUTIONS:
• Do not insert 8 cm discs (single CDs) into the
loading slot. (Such discs cannot be ejected.)
• Do not insert any disc of unusual shape—like a
heart or flower; otherwise, it will cause a
malfunction.
• Do not expose discs to direct sunlight or any
heat source or place them in a place subject to
high temperature and humidity. Do not leave
them in a car.
• Do not use any solvent (for example,
conventional record cleaner, spray, thinner,
benzine, etc.) to clean discs.
