General

•  This unit has been designed to reproduce 

CDs/CD Texts, and CD-Rs (Recordable)/CD-RWs 

(Rewritable) in audio CD (CD-DA), MP3/WMA/AAC 

formats.

•  When a disc is inserted upside down, “Please Eject” 

appears on the display. Press OPEN, then 

0

 to eject 

the disc.

•  In this manual, words “track” and “file” are 

interchangeably used.

•  While fast-forwarding or reversing on an MP3/WMA/

AAC/WAV file, you can only hear intermittent sound.

•  File/folder list may not appear correctly if too many 

hierarchies and folders are used.

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 which are detected first if a disc includes both 

audio CD (CD-DA) files and MP3/WMA/AAC 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 play back on this 

unit because of their disc characteristics, or for the 

following reasons:

  – 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.

•  If no operation is done for about 30 seconds after 

pressing MENU button or control dial, the operation 

will be canceled.

  Tuner operations

Storing stations in memory

•  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.

FM Radio Data System operations

•  Network-Tracking Reception requires two types 

of Radio Data System signals—PI (Programme 

Identification) and AF (Alternative Frequency) 

to work correctly. Without receiving these data 

correctly, Network-Tracking Reception will not 

operate correctly.

•  If a Traffic Announcement is received by TA Standby 

Reception, the volume level automatically changes 

to the preset level (TA Volume) if the current level is 

lower than the preset level.

•  When Alternative Frequency Reception is activated 

(with AF selected), Network-Tracking Reception is 

also activated automatically. On the other hand, 

Network-Tracking Reception cannot be deactivated 

without deactivating Alternative Frequency 

Reception. (See page 30.)

  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.
