JVC W-XC406, KW-XC405 manual Playing an MP3/WMA disc

•Some CD-Rs or CD-RWs may not play back on this unit because of their disc characteristics, and for the following causes:

–Discs are dirty or scratched.

–Moisture condensation occurs on the lens inside the unit.

–The pickup lens inside the unit is dirty.

–CD-R/CD-RW on which the files are written with “Packet Write” method.

–There are improper recording conditions (missing data, etc.) or media conditions (stain, scratch, warp, etc.).

•CD-RWs may require a longer readout time since the reflectance of CD-RWs is lower than that of regular CDs.

•Do not use the following CD-Rs or CD-RWs:

–Discs with stickers, labels, or protective seal stuck to the surface.

–Discs on which labels can be directly

printed by an ink jet printer.

Using these discs under high temperatures or high humidity may cause malfunctions or damages to the unit.
