NOTE
If a disc has both music data (CD-DA) and MP3/WMA/AAC files, playback of the two or

three file types differs depending on how the disc was recorded.
For details on data standards, refer to Playable audio files.

Copy controlled CDs (copyright protected CDs) that are not in accordance with standards

may not be able to playback.
Do not use non-conventional discs such as heart-shaped or octagonal discs. Otherwise, it

could damage the unit.
A new CD may have rough edges on its inner and outer perimeters. If a disc with rough

edges is used, proper setting will not be possible and the CD player will not play the CD.
In addition, the disc may not eject resulting in a malfunction. Remove the rough edges in
advance by using a ball-point pen or pencil as shown in the following figure. To remove
the rough edges, rub the side of the pen or pencil against the inner and outer perimeter of
the CD.
When driving on rough roads the sound may skip due to intense vibrations.

The CD may not work properly due to dust on the lens inside the device.

During cold and rainy weather, condensation (water droplets) in the player may occur

and cause it to not operate correctly. In this case, take the CD out and ventilate the cabin
or dehumidify it before using it.
Use discs that have been legitimately produced. If illegally-copied discs such as pirated

discs are used, the system may not operate properly.
The CD signal surface may become dirty if directly touched by hand, which may cause the

sound to skip. Hold the CD from the edge and center hole. Store the CD in a case out of
direct sunlight. Due to direct sunlight, high temperature and storage conditions in the
cabin, the CD may not playback.
When cleaning the CD, gently wipe off the dirt with a soft cloth from the center of the CD

to the edge. Do not use benzine, thinner and anti-static agents. Otherwise, the CD surface
may become damaged.
