Digital Audio Player

To get the best performance of the System, keep your discs 
and mechanism clean.

Handling discs
•  Remove the disc from its case by holding it at the edge 

while pressing the center hole lightly.

•  Do not touch the shiny surface of the disc, or bend the 

disc.

•  Put the disc back in its case after use.
•  Be careful not to scratch the surface of the disc when 

placing it back in its case.

•  Avoid exposure to direct sunlight, temperature extremes, 

and moisture.

To clean the disc:
•  Wipe the disc with a soft cloth in a straight line from center 

to edge.

Cleaning the System
•  Stains should be wiped off with a soft cloth. If the System is 

heavily stained, wipe it with a cloth soaked in water-diluted 
neutral detergent and wrung well, then wipe clean with a 
dry cloth.

•  Since the System may deteriorate in quality, become 

damaged or get its paint peeled off, be careful about the 
following:

  – DO NOT wipe it hard.
  – DO NOT wipe it with thinner or benzine.
  – DO NOT apply any volatile substance such as insecticides 

to it.

  – DO NOT allow any rubber or plastic to remain in contact 

for a long time.

\  The System has been turned on when the on-time comes. 

Timer starts working only when the System is turned off.

Turn the volume to minimum.

Press repeatedly to select “AUDIO IN.”

Start playing the Digital Audio Player connected.

Adjust the volume.

If the sound from the Digital Audio Player connected to the AUDIO IN jack is too loud or too quiet, you can change the audio 
input level through the AUDIO IN jack (without changing the volume level).

Press and hold for more than 2 seconds while “AUDIO IN” is selected as the source.
You can select one of three levels as follows:

•  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.

•  Do not use the following USB devices...
  – Whose rating is other than 5 V and exceeds 500 mA.
  – Equipped with special functions such as data security 

functions.

  – Divided by 2 or more partitions.
•  For the USB mass storage class device playback...
  – When connecting a USB mass storage class device, also 

refer to its manual.

  – Connect one USB mass storage class device to the System 

at a time. Do not use a USB hub.

  – This System is compatible with USB 2.0 Full Speed.
  – You can play back MP3/WMA files in a USB mass storage 

class device (maximum data transfer rate: 2 Mbps).

  – You cannot play back a file larger than 2 Gigabyte.
  – This System may not play back some USB mass storage 

class devices and does not support DRM (Digital Rights 
Management).

•  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).

•  This System can recognize up to 99 groups and 9 999 tracks 

(with a maximum number of 255 tracks in a group) in a USB
