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.
• 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.
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.
Disc can be neither played back nor
ejected.
• Unlock the disc.
• Eject the disc forcibly.
Disc sound is sometimes interrupted. • Stop playback while driving on rough roads.
• Change the disc.
• Check the cords and connections.
“NO DISC” appears on the display. Insert a playable disc into the loading slot.
“PLEASE” and “EJECT” appear
alternately on the display.
Press
0
, 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.)
A longer readout time is required
(“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.
The correct characters are not
displayed (e.g. album name).
This unit can only display letters (upper case), numbers, and
a limited number of symbols.
Installation/connection
The fuse blows. Connect the red and black leads correctly.
Power cannot be turned on. Check to make sure the yellow lead is connected.
No sound from the speakers. Check to make sure the speaker output lead is not
shortcircuited.
Sound is distorted. • Check to make sure the speaker output lead is grounded.
• Check to make sure the “–” terminals of L and R speakers
are grounded in common.
Noise interfere with sounds. Check to make sure the rear ground terminal connected to
the car’s chassis is using shorter and thicker cords.
This unit becomes hot. • Check to make sure the speaker output lead is grounded.
• Check to make sure the “–” terminals of L and R speakers
are grounded in common.
This unit does not work at all. Reset the unit. (See page 1.)
• CD-RWs may require a longer readout time since
the reflectance of CD-RWs is lower than that of
regular CDs.

extension code <.mp3> or <.wma> (regardless of
the letter case—upper/lower).

after pressing
MENU
button, the operation will be
canceled.
Tuner operations

General
• This unit has been designed to reproduce CDs/
CD Texts, and CD-Rs (Recordable)/CD-RWs
(Rewritable) in audio CD (CD-DA) and MP3/WMA

playback stops. Next time you select “CD” as the
playback source, playback will start from where it
had been stopped previously.

inside the unit.
– The pickup lens inside the unit is dirty.
– The files on the CD-R/CD-RW are written using the
“Packet Write” method.
– There are improper recording conditions (missing
data, etc.) or media conditions (stained, scratched,
