ferent folder.
¡ Do not write files other than compressed audio files.
¡ Playability may depend on the combination of writing soft-
ware and disc writer to be used.
¡ This unit does not support the play list function.
¡ Write files in a disc-at-once manner unless otherwise needed.
¡ You can shorten the duration between data read and playback
by decreasing the quantity of files or folders, or the depth of
the hierarchy.

Disc insert
The surfaces of new discs tend to be slippery. Therefore,
when using such a disc for the first time, it may not load
satisfactorily even when it has been inserted into the unit.
At a time like this, insert the disc into the unit as far as it
will go until it is loaded properly.
¡When inserting a disc into or ejecting and removing it
from the unit, insert it straight in or eject and remove
it straight out in parallel with the unit. Otherwise, the
disc may be scratched or marked in the process.
¡When inserting a disc, do not put one disc on another.
Failure to observe this may cause the discs to be
jammed.
Do not leave discs in the following places:¡Direct sunlight¡Near car heaters¡Dirty, dusty and damp areas¡On seats and dashboards
Disc cleaning
Use a dry, soft cloth to wipe from the center outward.
Do not attach any seals or labels to your discs.
Do not write on the disc label in a heavy pen or ballpoint
pen.
Notes on CD-Rs/RWs
¡You may have trouble playing back some CD-R/RW
discs recorded on CD recorders (CD-R/RW drives),
either due to their recording characteristics or dirt, fin-
gerprints, scratches, etc. on the disc surface.
¡CD-R/RW discs are less resistant to high temperatures and high humidity than ordinary music CDs. Leaving
them inside a car for extended periods may damage and
make playback impossible.
¡The unit may not successfully playback a CD-R/RW that was made by the combination of writing software, a CD
recorder (CD-R/RW drives) and a disc if they are incom-
patible with one another.
¡This player does not play CD-R/RW discs if the session is not closed.
¡Be sure to observe the handling instructions of CD- R/RW discs.
¡This player does not play CD-R/RW discs which contain other than CD-DA or MP3/WMA data.
