Disc/USB operations

Caution for DualDisc playback

• The Non-DVD side of a “DualDisc” does not comply
with the “Compact Disc Digital Audio” standard.
Therefore, the use of Non-DVD side of a DualDisc
on this product may not be recommended.
General
• This unit has been designed to reproduce CDs/CD
Texts, and CD-Rs (Recordable)/CD-RWs (Rewritable)
in audio CD (CD-DA), MP3 and WMA formats.
• If you change the source while listening to a disc,
playback stops. Next time you select “CD” as the
playback source, playback will start from where it
had been stopped previously.
• If the ejected disc is not removed within 15 seconds,
it is automatically inserted into the loading slot again
to protect it from dust. Playback starts automatically.

Troubleshooting
Symptom Remedy/Cause
General
Sound cannot be heard from the
speakers.
• Adjust the volume to the optimum level.
• Make sure the unit is not muted/paused. (See page 1.)
• Check the cords and connections.
“PROTECT” appears on the display and no
operations can be done.
Check to be sure the terminals of the speaker leads are
covered with insulating tape properly, then reset the
unit. (See page 1.)
If “PROTECT” does not disappear, consult your JVC car
audio dealer or a company supplying kits.
This unit does not work at all. Reset the unit. (See page 1.)
“AUX IN” cannot be selected. Check the <SRC SELECT>
=
<AUX IN> setting. (See
“Menu operations” on page 3.)
FM/AM
SSM automatic presetting does not work. Store stations manually.
Static noise while listening to the radio. Connect the antenna firmly.
“AM” cannot be selected. Check the <SRC SELECT>
=
<AM> setting. (See “Menu
operations” on page 3.)
Disc playback
Disc cannot be played back. Insert the disc correctly.
• CD-R/CD-RW cannot be played back.
• Tracks on the CD-R/CD-RW cannot be
skipped.
• Insert a finalized CD-R/CD-RW.
• Finalize the CD-R/CD-RW with the component which
you used for recording.

, then insert a disc correctly.
MP3/WMA playback
Disc cannot be played back.
• Use a disc with MP3/WMA tracks recorded in a format
compliant with ISO 9660 Level 1, Level 2, Romeo, or Joliet.
• Add the extension code <.mp3> or <.wma> to the file
names.
Noise is generated. Skip to another track or change the disc. (Do not add
the extension code <.mp3> or <.wma> to non-MP3 or
WMA tracks.)

(“READING” keeps flashing on the display).
Do not use too many hierarchical levels and folders.
Tracks are not played back in the order
you have intended.
Playback order is determined when the files are
recorded.
The elapsed playing time is not correct. This sometimes occurs during playback. This is caused
by how the tracks are recorded on the disc.

display.
Selected folder is an empty folder *. Select another
folder that contains MP3/WMA tracks.
* Folder that is physically empty or folder that contains data
but does not contain valid MP3/WMA track.
