Placement
Set the unit up on an even surface away from direct sunlight, high
temperatures, high humidity, and excessive vibration. These
conditions can damage the cabinet and other components, thereby
shortening the unit’s service life.
Do not place heavy items on the unit.
Voltage
Do not use high voltage power sources. This can overload the unit
and cause a fire.
Do not use a DC power source. Check the source carefully when
setting the unit up on a ship or other place where DC is used.

How discs with MP3 differ from CDs
This unit can play MP3 files recorded on CD-R/RW with a computer.
Files are treated as tracks and folders are treated as albums.
This unit can access up to 999 tracks, 195 albums and 20 sessions.
When making MP3 files to play on this unit
Disc format
Discs must conform to ISO9660 level 1 or 2 (except for extended
formats).
File format
MP3 files must have the extension “.MP3” or “.mp3”.
To play in a certain order
Prefix the folder and file names with 3-digit
numbers in the order you want to play them.
Files may not be recorded in numbered order if
the prefixes have different numbers of digits.
For example: 1????.mp3, 2????.mp3, 10????.mp3.
However, some writing software may also
cause recording to occur in a different order.
MPEG Layer-3 audio decoding technology

multimedia.
Limitations on MP3 play
•This unit is not compatible with packet-write format.
•When both MP3 and CD-DA data is recorded on the disc over a
number of sessions:
•If the first session contains MP3 recordings, the unit will play from
the MP3 made in that session till the session before the first CD-DA
recordings.
•If the first session contains CD-DA recordings, the unit will play only
the recordings made in that session. The subsequent sessions will
be ignored.
•Maximum number of displayable characters:
Album/track title: 21
ID3 title/artist name: 24
Text data that the unit doesn’t support cannot be displayed.
(ID3 is a tag embedded in MP3 track to provide information about
the track.)
•You cannot use 1-RANDOM play, A-RANDOM play, search function,
and time access function.
•Some MP3 may not be played due to the condition of the disc or
recording.
•Recordings will not necessarily be played in the order you recorded
them.
