Troubleshooting

What appears to be trouble is not always serious. Check the following points before calling a service 
center.

Maintenance

  How to clean the connectors

Frequent detachment will deteriorate the 
connectors.
To minimize this possibility, periodically wipe 
the connectors with a cotton swab or cloth 
moistened with alcohol, being careful not to 
damage the connectors.

  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.

  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

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.

  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.
