magazines when not in use.
• Do not subject discs to heat/high temperature.
Avoid leaving them in a parked car or on a
dashboard/rear tray.
• Do not attach labels, or use discs with sticky
ink/residue. Such discs may stop spinning
when used, causing a malfunction, or may ruin
the disc.
• Do not use any discs with labels or stickers
attached.
The following malfunctions may result from
using such discs:
– Inability to eject a disc (due to a label or
sticker peeling off and jamming the eject
mechanism).
– Inability to read audio data correctly (e.g.,
playback skipping, or no playback) due to
heat shrinking of a sticker or label causing a
disc to warp.
• Discs with non-standard shapes (e.g., heart,
square, star) cannot be played on this unit.
Attempting to do so may damage the unit. Do
not use such discs.

Note on DualDiscs
A DualDisc is a two sided disc product which
mates DVD recorded material on one side with
digital audio material on the other side. However,
since the audio material side does not conform to
the Compact Disc (CD) standard, playback on
this product is not guaranteed.

Notes
• Be sure to finalize the disc before using on the unit.
• When naming an MP3 file, be sure to add the file
expansion ".mp3" to the file name.
• If you play a high-bit-rate MP3, such as 320 kbps,
sound may be intermittent.
• During playback of a VBR (variable bit rate) MP3 file
or fast-forward/reverse, elapsed playing time may
not display accurately.
• When the disc is recorded in Multi Session, only the
first track of the first session format is recognized
and played (any other format is skipped). The
priority of the format is CD-DA and MP3.
– When the first track is a CD-DA, only CD-DA of the
first session is played.
– When the first track is not a CD-DA or MP3
session is played. If the disc has no data in any of
these formats, "NO MUSIC" is displayed.
• The unit cannot play back Multi Border recorded
MP3.
• MP3 files not recorded at 44.1 kHz or 48 kHz
sampling rate and 64 to 320 kbps bit rate cannot be
played.
Note on wireless
transmission
The unit transmits audio/video at FM 2.4 GHz.
Simultaneous use with other 2.4 GHz equipment
may cause image interference or audio noise.
This is not a malfunction, but a result of
equipment sharing the same operating frequency.
