Disc 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.

•  MP3 and WMA “tracks” (words “file” and “track” are 

used interchangeably) are recorded in “folders.” 

•  When a disc is inserted upside down, “PLEASE” and 

“EJECT appear alternately on the display. Press 

0

 to 

eject the disc.

•  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 which are 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 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.

More about this unit

Basic operations 

Turning on the power

•  By pressing SRC or AUX on the unit, you can also turn 

on the power. If the source is ready, playback also 

starts.

Turning off the power

•  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.

Tuner operations 

Storing stations in memory

•  During SSM search...

  – All previously stored stations are erased and the 

stations are stored anew.

  – Received stations are preset in No. 1 (lowest 

frequency) to No. 6 (highest frequency).

  – When SSM is over, the station stored in No. 1 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 RDS operations

•  Network-Tracking Reception requires two types of 

RDS 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 VOL) 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. 

•  If you want to know more about RDS, visit
