MORE ABOUT THIS UNIT

Basic operations

• By pressing SRC on the unit, you can also turn on the
power. If the source is ready, playback also starts.

• 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.

• When no disc is loaded in the unit, you cannot select “CD”
as the playback source.

Tuner operations

• 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.

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.

Unusual shape

Transparent or semi-transparent
parts on its recording area

General

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

• After ejecting a disc, “NO DISC” appears and you cannot
operate some of the buttons. Insert another disc or press
SRC to select another playback source.

Playing a CD-R or CD-RW

• Use only “finalized” CD-Rs or CD-RWs.

• 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:

– 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.

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.
