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.

–When SSM is over, the station stored in the lowest preset number will be automatically tuned in.

•When storing a station manually, the previously preset station is erased when a new station is stored in the same preset number.

•If you try to assign titles to more than 30 station frequencies, “NAME FULL” appears. Delete unwanted titles before assignment.

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.

•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.

Playing a CD-R or CD-RW

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

•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.
