Caution on volume setting:
Digital devices (CD/USB) produce very little noise
compared with other sources. Lower the volume
before playing these digital sources to avoid
damaging the speakers by sudden increase of the
output level.

Installing the lithium coin battery
(CR2025)
Aim the remote controller directly at the remote
sensor on the unit. Make sure there is no obstacle
in between.
Warning:
• Do not install any battery other than CR2025 or
its equivalent; otherwise, it may explode.
• Do not leave the remote controller in a place
(such as the dashboard) exposed to direct
sunlight for a long time; otherwise, it may
explode.
• Store the battery in a place where children

Maintenance
How to clean the connectors
Frequent detachment will deteriorate the connectors.
To minimize this possibility, periodically wipe the
connectors with a cotton swab or cloth moistened with
alcohol, being careful not to damage the connectors.
Connectors
Moisture condensation
Moisture may condense on the lens inside the unit in
the following cases:
• After starting the heater in the car.
• If it becomes very humid inside the car.
Should this occur, the unit may malfunction. In this
case, eject the disc and leave the unit turned on for a
few hours until the moisture has evaporated.
How to handle discs
When removing a disc from its
case, press down the center holder
of the case and lift the disc out,
holding it by the edges.
• Always hold the disc by the edges. Do not touch its
recording surface.
When storing a disc in its case, gently insert the
disc around the center holder (with the printed surface
facing up).
• Make sure to store discs in cases after use.
Center holder
To keep discs clean
A dirty disc may not play correctly.
If a disc does become dirty, wipe it with
a soft cloth in a straight line from center
to edge.
• Do not use any solvents (for example, conventional
record cleaner, spray, thinner, benzine, etc.) to clean
discs.
To play new discs
New discs may have some rough spots
around the inner and outer edges. If
such a disc is used, this unit may reject
the disc.
To remove these rough spots, rub the edges with a
pencil or ball-point pen, etc.
Do not use the following discs:
Single CD (8 cm disc)
Sticker and
sticker residue
Unusual shape
Warped disc
Stick-on label

Basic operations
Turning on the power
ENGLISH
• By pressing SRC or AUX on the unit, you can also turn
on the power. If the source is ready, playback also
starts.
Turning off the power
• If you turn off the power while listening to a disc,
disc play will start from where it had been stopped
previously next time you turn on the power.
Tuner operations
Storing stations in memory
• During SSM search...
– All previously stored stations are erased and the
stations are stored anew.
– Received stations are preset in No. 1 (lowest
frequency) to No. 6 (highest frequency).
– When SSM is over, the station stored in No. 1 will
be automatically tuned in.
• When storing a station manually, the previously
preset station is erased when a new station is stored
in the same preset number.
Disc 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.
• MP3 and WMA “tracks” (words “file” and “track” are
used interchangeably) are recorded in “folders.”
• When a disc is inserted upside down, “PLEASE” and
“EJECT appear alternately on the display. Press 0 to
eject the disc.
• While fast-forwarding or reversing on an MP3 or
WMA disc, you can only hear intermittent sounds.
Playing a CD-R or CD-RW
• Use only “finalized” CD-Rs or CD-RWs.
• This unit can only play back files of the same type as
those which are detected first if a disc includes both
audio CD (CD-DA) files and MP3/WMA files.
• This unit can play back multi-session discs; however,
unclosed sessions will be skipped while playing.
• Some CD-Rs or CD-RWs may not be played back on
this unit because of their disc characteristics, or for
the following reasons:
– Discs are dirty or scratched.
– Moisture condensation has occurred on the lens
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,
warped, etc.).
• CD-RWs may require a longer readout time since the
reflectance of CD-RWs is lower than that of regular
CDs.
• Do not use the following CD-Rs or CD-RWs:
– Discs with stickers, labels, or protective seal stuck
to the surface.
– Discs on which labels can be directly printed by an
ink jet printer.
Using these discs under high temperature or high
humidity may cause malfunctions or damage to the
unit.

This unit is designed to operate on 12 V DC, NEGATIVE ground electrical systems. If your vehicle does
not have this system, a voltage inverter is required, which can be purchased at JVC car audio dealers.
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 speakers with a 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 page 13 of the INSTRUCTIONS).
• To prevent short circuits, 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.
PRECAUTIONS on power supply and speaker connections:
• DO NOT connect the speaker leads of the power cord to the car battery; otherwise, the unit
will be seriously damaged.
• BEFORE connecting the speaker leads of the power cord to the speakers, check the speaker wiring in
your car.
