CAUTION
• The operating temperature of this product is 5°C to
35°C. Use in temperatures outside this range may
cause a malfunction or damage the product.
Under the following conditions, you may not be
able to operate this product properly due to con-
densation formed on the lens of the main unit:
• When you have just started an air conditioner to
warm your room
• When you have placed the main unit at an area
with high humidity
• When you have moved the main unit from a cold
place to a warm place
When condensation forms, leave the main unit
turned on, wait for approximately 1 or 2 hours, and
then operate the main unit.

• Do not wipe the operation panel with thinners, ben-
zenes or other chemical agents. Do not spray
insecticides onto the operation panel. These may
cause discoloration and damage to the surface.
When using headphones, keep the volume at a
moderate level so as not to over-stimulate your
ears.
■When enjoying sound from the speakers,
adjust the volume to a suitable level to
avoid disturbing your neighbors.
Even low-volume sound carries a long way,
especially at night. Show consideration to
your neighbors by closing windows or using
headphones.

Introduction English
• Discs should be finalized before being played back.
1 Among MP3/WMA/JPEG discs, only discs formatted
with ISO 9660 (known as UDF Bridge) are playable.
2 Only when a DVD-RW is compatible with CPRM
(Content Protection for Recordable Media), DVD VR
format can be used.
3 A DivX formatted DVD-ROM is also playable.
It is possible to play back finalized +R/+RW (DVD Video
Format only) discs. "DVD" lights on the front display
panel when a +R/+RW disc is loaded.
Some discs may not be played back because of their disc
characteristics, recording conditions, or damage or stains
on them.
Only sounds can be played back from the following discs:
MIX-MODE CD CD-G
CD-EXTRA CD TEXT
Region code of DVD VIDEO
DVD players and DVD VIDEOs have their own
region code numbers. This product can only play
back a DVD VIDEO recorded with the region code
number "3" (or any region code number that
includes "3") or "ALL".
If a DVD VIDEO with an improper region code
number is loaded, "REGION CODE ERROR!"
appears on the TV screen and playback cannot
start.
• On some DVD VIDEOs, DVD AUDIOs, VCDs,
SVCDs or DivX discs, their actual operation
may be different from what is explained in
this manual. This is due to the disc program-
ming and disc structure, not a malfunction of
this product.
Discs you can play back:
• Playback is impossible in some cases
due to the disc characteristics, recording
condition, scratches or dirt on the disc, or
dirt or condensation on the lens.
• Before using a disc, carefully read the
cautions regarding the disc.
• This product does not support playback
or CD text display of sound files such as
MP3s.
• To play back a CD-RW or DVD-RW on
this product, erase all tracks if the CD-
RW or DVD-RW was recorded in a format
other than the format described on the
left. Using the CD-RW or DVD-RW with-
out erasing all tracks may result in dam-
age to the speakers or other parts caused
by sudden loud volume.
Discs that cannot be played back
• The following discs cannot be played back:
DVD-ROM (except for MP3/WMA/JPEG/ASF/
DivX format), DVD-RAM, CD-ROM, CD-I (CD-I
Ready), Photo CD, SACD, etc.
Playing back these discs will generate noise and
damage the speakers.
• Damaged discs and discs in an extraordinary
shape (other than a disc of 12 cm or 8 cm in
diameter) cannot be played back.
• JVC do not guarantee the operation and sound
quality of discs not authorized by CD-DA, which
is a CD specification.
Before playback, confirm that the disc complies
with this CD specification by checking the marks
and reading notes printed on the package.

About MP3/WMA/JPEG/ASF/DivX discs
Playable MP3/WMA/JPEG/ASF/DivX discs and
files
• CDs recorded in the ISO 9660 format are play-
able (except CDs recorded in the "packet write"
format (UDF format)).
• CDs recorded in the multi-session format are
also playable.
• Files with an extension of ".mp3", ".wma", ".jpg",
".jpeg", ".asf", ".divx", ".div" or ".avi" (extensions
with uppercase and lowercase letters mixed are
also acceptable) are playable.
• This product cannot play back DVDs recorded in
multi-session or multi-border format.
Notes on MP3/WMA/JPEG/ASF discs and files
• A disc may not be played back, or reading it may
take a long time depending on its recording con-
ditions or properties.
• The time needed for reading varies with the num-
ber of groups or tracks (files) recorded on the disc.
• If a character other than single byte English
characters is used in the file name of an MP3/
WMA/JPEG/ASF file, the track/file name will not
be displayed correctly.
• The order of tracks/groups displayed on the
MP3/WMA Control screen, and the order of files/
groups displayed on the JPEG Control screen
may be different from that of files/folders dis-
played on PC's monitor screen.
• In the case of MP3/WMA discs, since groups/
tracks are played back in alphabetical order, a
commercially available MP3/WMA disc may be
played back in an order different from that indi-
cated on the label attached to the disc.
• Playing back an MP3/WMA file including a still
image may take a long time. The elapsed time is
not displayed until playing back starts. If playing
back starts, the elapsed time may not be dis-
played correctly.
• For an MP3/WMA file, a disc with a sampling fre-
quency of 44.1 kHz and transmission rate of 128
kbps is recommended.
• This product is not compatible with MP3i or
MP3PRO.
• This product can play back a baseline JPEG file,
excluding monochromatic JPEG files.
• This product can play back JPEG data taken with a
digital camera conforming to the DCF (Design
Rule for Camera File System) standard (when a
function is applied such as the automatic rotation
function of a digital camera, data goes beyond the
DCF standard, so the image may not be dis-
played).
• If data has been processed, edited and restored
with PC image editing software, the data may
not be displayed.
• This product cannot play back animations such
as MOTION JPEG, or still pictures (TIFF etc.)
other than JPEG, and image data with sound.
• The resolution of 640 x 480 pixels is recom-
mended for JPEG files. If a file has been
recorded at a resolution of more than 640 x 480
pixels, display may take a long time. An image
with a resolution of more than 8192 x 7680 pix-
els cannot be displayed.
• The system supports ASF files recorded with the
maximum bit rate of 384 kbps and an audio
coder decoder of G.726.
Notes on DivX discs and files
• The system supports DivX 5.x, 4.x and 3.11.
• The system supports DivX files with a resolution
of 720 x 480 pixels or less (30 fps) and 720 x
576 pixels or less (25 fps).
• Audio stream should conform to MPEG1 Audio
Layer-2 or MPEG Audio Layer-3 (MP3).
• The system does not support GMC (Global
Motion Compression).
• Files encoded in the interlaced scanning mode
may not be played back correctly.
• Playing back a DivX disc may take a long time.
The elapsed time is not displayed until playback
starts. The elapsed time may also not be dis-
played correctly.

Introduction English
DVD VIDEO
A DVD VIDEO consists of "titles" and each title
may be divided into "chapters".
DVD AUDIO
A DVD AUDIO consists of "groups" and each
group may be divided into "tracks".
Some discs include a "bonus group" that requires
a password for playing ( page 31).
VCD/SVCD/CD
VCD, SVCD and CD consist of "tracks".
In general, each track has its own track number.
(On some discs, each track may also be further
divided by indexes.)
MP3/WMA/JPEG/ASF/DivX discs
On an MP3/WMA/JPEG/ASF/DivX disc, each still
picture (material) is recorded as a track [file].
Tracks [Files] are usually grouped into a folder.
Folders can also include other folders, creating
hierarchical folder layers.
This unit simplifies the hierarchical construction of
a disc and manages folders by "groups".
This product can recognize up to 4000 tracks [files]
in a disc. Also, the product can recognize up to
150 tracks [files] per group and up to 99 groups in
a disc. Since the unit ignores the tracks [files]
whose numbers are exceeding 150 and the groups
whose numbers are exceeding 99, they cannot be
played back.
• If there is any type of files other than MP3/WMA/
JPEG/ASF/DivX files in a disc, those tracks
[files] are also counted in the total file number.
Regarding TV mode
This product is suitable for NTSC. The discs using
TV mode other than NTSC (such as PAL) is
converted into NTSC mode before playback.
NOTE
• Some discs may not be played properly, for exam-
ple, the picture movement may not be smooth, or
the aspect ratio (ratio of length and width) may be
changed.

Listening Point
• Multi-channel center audio is separated and out-
put through the center surround speaker.
About Front Surround Function
Instead of the traditional 5.1 channel playback system,
we have introduced a virtual surround system that uti-
lizes four speakers situated in the front.
The mechanism is based on an original JVC technique
in which two center speakers, separated by the aver-
age distance between two human ears, deal with the
center signals and the surround signals, while the LFE
(low frequency sound effect) is added to steady the L
channel signal and the R channel signal that are trans-
mitted to the main speakers on the left and right sides.
A high quality digital amplifier drives the speakers at
30W x 4ch.
Characteristics of 4-Speaker Front Surround
• Our original speaker layout and signal processing
does not only save space, but it also ensures a
more realistic sound field.
• Since high quality sound is produced using basic 2
channel stereo, it is ideal for playing music.
• The center surround speaker allows listeners to
enjoy realistic speech localization.
• It provides realistic surround effects, with wider lis-
tening points for both front and back areas.

CAUTION
• Connect the main unit directly with a TV (or a
monitor) without routing through a VCR. Otherwise
it may cause picture distortion while playing back.
(Such picture distortion is caused by a copy
protection system, and thus it is not a malfunction.)
Also, if the main unit is connected to a TV with a
built-in VCR, there may be picture distortion during
playback.
NOTE
• You need to set "MONITOR TYPE" in the
"PICTURE" menu correctly according to the aspect
ratio of your TV. ( page 41)
You can enjoy pictures of better quality using the
following cord instead of the supplied video cord.
You can enjoy better quality pictures than when
using the S-video cord.
CAUTION
• Use one of either the S-video cord or the compo-
nent video cord. If both cords are used, pictures
may not be played back properly.
NOTE
• In order to enjoy pictures with the progressive
mode ( page 30), the TV is required to have
progressive video input.
