  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 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 has evaporated.

  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 in its case,

 gently insert the 

disc around the center holder (with the printed surface 

facing up).

•  Make sure to store discs in cases after use.

Center holder

  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 solvents (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.

Do not use the following discs:

Single CD (8 cm) disc

Warped disc

Sticker and sticker residue

Stick-on label

Unusual shape

C-thru Disc (semi-

transparent disc)
