WARNINGS
To prevent short circuits, we recommend that you disconnect the battery’s
negative terminal and make all electrical connections before installing the unit.
• Be sure to ground this unit to the car’s chassis again after installation.
Notes:
• Replace the fuse with one of the specified rating. If the fuse blows frequently,
consult your JVC car audio dealer.
• It is recommended to connect to the speakers with maximum power of more
than 50 W (both at the rear and at the front, with an impedance of 4 Ω to
8 Ω). If the maximum power is less than 50 W, change “AMP GAIN” setting to
prevent the speakers from being damaged (see “General settings—PSM”).
• To prevent short-circuit, cover the terminals of the UNUSED leads with
insulating tape.
• The heat sink becomes very hot after use. Be
careful not to touch it when removing this unit.

PREPARATION
Symptoms Remedies/Causes
General
• Sound cannot be heard from the speakers. • Adjust the volume to the optimum level.
• Check the cords and connections.
• The buttons on the unit do not work as you
intended.
If you press M MODE, some buttons work differently from it
original function. Wait for 5 seconds or press M MODE again.
• This unit does not work at all. Reset the unit.
FM/AM
• SSM automatic presetting does not work. Store stations manually.
• Static noise while listening to the radio. Connect the antenna firmly.
Disc playback
• Disc ejects. 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.
MP3/WMA playback
• Disc cannot be played back. • Use a disc with MP3/WMA tracks recorded in the 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 (“CHECK”
keeps flashing on the display).
Do not use too many hierarchies and folders.
• Tracks are not played back in the order you
have intended.
Playback order is determined when the files are recorded.
• Elapsed playing time is not correct. This sometimes occurs during play. This is caused by how the
tracks are recorded on the disc.
• “PLEASE” and “EJECT” appear alternately
on the display.
Insert a disc that contains MP3/WMA tracks.
• Correct characters are not displayed (e.g.
album name).
This unit can only display alphabets (upper case), numbers, and a
limited number of symbols.
