More about this unit

Basic operations

General

•If you turn off the power while listening to a track, playback will start from where it had been stopped previously next time you turn on the power.

•If no operation is done for about 60 seconds after pressing MENU button, the operation will be canceled.

Tuner operations

•During SSM search...

–All previously stored stations are erased and the

stations are stored anew.

Disc/USB operations

Caution for DualDisc playback

•The Non-DVD side of a “DualDisc” does not comply with the “Compact Disc Digital Audio” standard. Therefore, the use of Non-DVD side of a DualDisc on this product may not be recommended.

General

•This unit has been designed to reproduce CDs/CD Texts, and CD-Rs (Recordable)/CD-RWs (Rewritable) in audio CD (CD-DA), MP3 and WMA formats.

•If you change the source while listening to a disc, playback stops. Next time you select “CD” as the playback source, playback will start from where it had been stopped previously.

•When a disc is inserted upside down, “PLEASE” and “EJECT” appear alternately on the display. Press 0 to eject the disc.

•If the ejected disc is not removed within

15 seconds, it is automatically inserted into the loading slot again to protect it from dust. Playback starts automatically.

•MP3 and WMA “tracks” (words “file” and “track” are used interchangeably) are recorded in “folders.”

•While fast-forwarding or reversing on an MP3 or WMA disc, you can only hear intermittent sounds.

Playing a CD-R or CD-RW

•Use only “finalized” CD-Rs or CD-RWs.

•This unit can only play back files of the same type as those detected first if a disc includes both audio CD (CD-DA) files and MP3/WMA files.

•This unit can play back multi-session discs; however, unclosed sessions will be skipped while playing.

•Some CD-Rs or CD-RWs may not be played back on this unit:

–Discs are dirty or scratched.

–Moisture condensation has occurred on the lens inside the unit.

–The pickup lens inside the unit is dirty.

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

–There are improper recording conditions (missing data, etc.) or media conditions (stained, scratched, warped, 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 a protective seal stuck to the surface.

–Discs on which labels can be directly printed by an ink jet printer.

Using these discs under high temperature or high humidity may cause malfunctions or damage to the unit.
