MAINTENANCE
Center holder
Handling CDs
This unit has been designed to reproduce CDs
and CD-Rs.
• Other discs cannot be played back.
How to handle CDs
When removing a CD from
its case, press down the
center holder of the case
and lift the CD out,
holding it by the edges.
• Always hold the CD by
the edges. Do not touch its recording surface.
When storing a CD into its case, gently insert the
CD around the center holder (with the printed
surface facing up).
• Make sure to store CDs into the cases after
use.
To keep CDs clean
A dirty CD may not play
correctly. If a CD does
become dirty, wipe it with a
soft cloth in a straight line
from center to edge.
To play new CDs
New CDs may have some
rough spots around the
inner and outer edges. If
such a CD is used, this unit
may reject the CD.
To remove these rough
spots, rub the edges with a
pencil or ball-point pen, etc.
About mistracking:
Mistracking may result from driving on extremely
rough roads. This does not damage the unit and
the CD, but will be annoying.
We recommend that you stop CD play while
driving on such rough roads.
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 CD and leave
the unit turned on for a few hours until the
moisture evaporates.
When playing a CD-R (Recordable)
You can play back your original CD-Rs on this
receiver.
• Before playing back CD-Rs, read their
instructions or cautions carefully.
• Some CD-Rs recorded on CD recorders may
not be played back on this receiver because of
their disc characteristics, and of the following
reasons:
– Discs are dirty or scratched.
– Moisture condensation occurs on the lens
inside the unit.
– The pickup lens inside the CD player is dirty.
• Use only “finalized” CD-Rs.
• CD-RWs (Rewritable) cannot be played back
on this receiver.
• Do not use CD-Rs with stickers or sticking
labels on the surface. They may cause
malfunctions.
CAUTIONS:
• Do not insert 8 cm CDs (single CDs) into the
loading slot. (Such CDs cannot be ejected.)
• Do not insert any CD of unusual shape — like a
heart or flower; otherwise, it will cause a
malfunction.
• Do not expose CDs 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 CDs.
