Basic and Common Operations (see page 3)
•  Pressing one of the source buttons also turns on the 

System and starts playing back.

Playing Back a Disc (see page 4)
•  This System cannot play “packet write” discs.
•  For MP3/WMA playback...
  – In this manual, “file” and “track” are interchangeably used 

for MP3/WMA operations.

  – This System can show the Tag data (Version 1).
  – MP3/WMA discs are required a longer readout time than 

regular CDs. (It depends on the complexity of the group/
file configuration.)

  – Some MP3/WMA files cannot be played back and will be 

skipped. This result from their recording processes and 
conditions.

  – When making MP3/WMA discs, use ISO 9660 Level 1 or 

Level 2 for the disc format.

  – This System can play back MP3/WMA files with the 

extension code <.mp3> or <.wma> (regardless of the 
letter case—upper/lower).

  – It is recommended that you make each MP3/WMA file 

at a sampling rate of 44.1 kHz and at bit rate of 128 kbps. 
This System cannot play back files made at bit rate of less 
than 64 kbps.

  – Playback order of MP3/WMA tracks may be different from 

the one you have intended while recording. If a folder 
does not include MP3/WMA tracks, they are ignored.

•  This System can recognize up to 99 groups in a disc. The 

total number of groups and tracks in a disc that can be 
recognized by the System is 512 (for MP3/WMA).

  – Playable files which do not belong to any groups are 

handled as Group 1.

Listening to iPod (see page 6)
•  If the iPod does not play correctly, update your iPod 

Software to the latest version. For details about updating 
your iPod, check on the Apple web site 
<http://www.apple.com>.

•  The iPod battery cannot be charged while the System is in 

the Save mode.

•  When the iPod is not charged through the System, the 

iPod may not be turned on from the System.

•  You cannot send any data to your iPod from the System.
•  Sound distortion may occur when playing back audio 

sources with high recording levels. When distortion occurs, 
it is recommended to turn off the equalizer of the iPod. For 
information on operating the iPod, see the iPod instruction 
manual.

•  Do not touch or hit the iPod terminal pins or connector 

pins directly. It might cause damages to the connector 
part.

Setting the Clock and Using Timers (see page 7)
•  You can set the clock and Daily Timer even while the Save 

mode is turned on. While setting the clock or Daily Timer, 
the display is turning on.

•  The clock may gain or lose 1 to 2 minutes per month. If this 

happens, readjust the clock.

•  When you unplug the AC power cord or if a power failure 

occurs, the clock and the timer will be canceled. You need 
to set the clock first, then the timer again.

Timer Priority:
•  If you set the Sleep Timer after Daily Timer starts playing 

the selected source, Daily Timer is canceled.
