Additional Information
Learning More about This System
Daily Operations—Playback (see pages 9 to 14)
Listening to the Radio:
•If you store a new station into an occupied preset number, the 
previously stored station in that number will be erased.
•When you unplug the AC power cord or if a power failure 
occurs, the preset stations will be erased in a few days. If this 
happens, preset the stations again.
Playing Back a Disc:
•When using an 8 cm (3-3/16 inch) disc, place it on the inner 
circle of the disc tray.
•This System cannot play “packet write” discs.
•For MP3 playback...
–MP3 discs are required a longer readout time than regular 
CDs. (It depends on the complexity of the group/file 
configuration.)
–Some MP3 files cannot be played back and will be skipped. 
This result from their recording processes and conditions.
–When making MP3 discs, use ISO 9660 Level 1 or Level 2 
for the disc format.
–This System can play back MP3 files with the extension 
code  (regardless of the letter case—upper/lower).
–Some characters or symbols will not be shown correctly on 
the display.
The maximum character number shown on the display is 32 
(without the extension code) for files, and 30 for ID3 tag.
–It is recommended that you make each MP3 file at a 
sampling rate of 44.1 kHz and at bit rate of 128 kbps.
–This System can recognize the total of 500 tracks and of 200 
groups. Those exceeding the maximum number cannot be 
recognized.
–Playback order of MP3 tracks may be different from the one 
you have intended while recording. If a folder does not 
include MP3 tracks, they are ignored.
When discs* in more than one tray are loaded on the disc 
trays, they are played in sequence as follows:
Ex.: When CD 2 is selected:
CD 2 -> CD 3 -> CD 4 -> CD 5 -> CD 1 (then selects 
CD 2, and stops)
*When no disc is loaded on the tray, that disc number is 
skipped.
You can exchange discs while playing or selecting another 
disc.
Quick Portable Link (QP Link)
•The system holds the On/Off status of QP Link even when 
the AC power cord is connected or removed.
•The source remains at AUX when you stop the other 
equipment such as a digital audio player.
