More about this unit

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.

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.

Playing an MP3/WMA disc

•This unit can play back MP3/WMA files with the extension code <.mp3> or <.wma> (regardless of the letter case—upper/lower).

•This unit can show the names of albums, artists (performer), and tag (Version 1.0, 1.1, 2.2, 2.3, or 2.4) for MP3 files and for WMA files.

•This unit can display only one-byte characters. No other characters can be correctly displayed.

•This unit can play back MP3/WMA files meeting the conditions below:

–Bit rate: MP3: 32 kbps — 320 kbps

WMA: 32 kbps — 192 kbps

•This unit can recognize a total of 512 files, 255 folders, and 8 hierarchical levels.

•This unit can play back files recorded in VBR (variable bit rate).

Files recorded in VBR have a discrepancy in the elapsed time display, and do not show the actual elapsed time. In particular, this difference becomes noticeable after performing the search function.

•This unit cannot play back the following files:

–MP3 files: encoded in MP3i and MP3 PRO format;

an inappropriate format; layer 1/2.

–WMA files: encoded in lossless, professional, and voice format; not based upon Windows Media® Audio; copy-protected with DRM.

–Files which have data such as AIFF, ATRAC3, etc.

•The search function works but search speed is not constant.
