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

Ω

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.
• “PLEASE” and “EJECT” appear alternately

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 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 alphabets (upper case), numbers, and a
limited number of symbols.
