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 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.

• Microsoft and Windows Media are either registered trademarks or trademarks of Microsoft Corporation in the United

States and/or other countries.
