Getting Started
Putting Batteries in the Remote Control
Before using the remote control, put two supplied batteries first.
• When using the remote control, aim the remote control directly at
the remote sensor on the center unit.
1. On the back of the remote control, remove the
battery cover.
2. Insert batteries. Make sure to match the polarity:
(+) to (+) and (–) to (–).
3. Replace the cover.
If the range or effectiveness of the remote control decreases, replace
the batteries. Use two UM-4“AAA”/IEC “R03” type dry-cell
batteries.
CAUTION:
Follow these precautions to avoid leaking or cracking cells:
•Place batteries in the remote control so they match the polarity: (+)
to (+) and (–) to (–).
•Use the correct type of batteries. Batteries that look similar may
differ in voltage.
•Always replace both batteries at the same time.
•Do not expose batteries to heat or flame.
Before Installation
General Precautions
• DO NOT insert any metal object into the center unit.
• DO NOT disassemble the center unit or remove screws, covers, or
cabinet.
• DO NOT expose the center unit to rain or moisture.
Locations
• Install the center unit in a location that is level and protected from
moisture.
• The temperature around the center unit must be between 5˚C and
35˚C (41˚F and 95˚F).
• Make sure there is good ventilation around the center unit. Poor
ventilation could cause overheating and damage the center unit.
Handling the center unit
• DO NOT touch the power cord with wet hands.
• DO NOT pull on the power cord to unplug the cord. When
unplugging the cord, always grasp the plug so as not to damage
the cord.
• Keep the power cord away from the connecting cords and the
antenna. The power cord may cause noise or screen interference. It
is recommended to use a coaxial cable for antenna connection,
since it is well-shielded against interference.
• When a power failure occurs, or when you unplug the power cord,
the preset settings such as preset FM/AM channels and sound
adjustments may be erased in a few days.
Checking the Supplied Accessories
Check to be sure you have all of the following supplied accessories.
The number in the parentheses indicates the quantity of the pieces
supplied.

Connecting the Speakers
Connect the satellite speakers and subwoofer to the terminals on the
rear panel using speaker cords supplied.
Labels are attached to the speaker cords to indicate  the terminals to
be connected.
• Connect the red cord to the red (+) terminal, and the black cord to
the black (–) terminal respectively.
CAUTION:
Use speakers with the SPEAKER IMPEDANCE indicated by the
speaker terminals.
Connecting speaker cords to the terminals
1Press and hold the terminal clamp.
2Insert the speaker cord.
3Release the finger from the clamp.
Notes:
•If the speaker cord is covered with vinyl, remove the
vinyl by twisting it as shown in the diagram.
•Make sure the core wire of speaker cords do not expose
to out of the terminals.This could cause short-circuit.
When setting the speakers
To obtain the best possible sound from this system, you need to
place all the speakers except the subwoofer at the same distance
from the listening position with each front faced toward the listener.
Since bass sound is non-directional, you can place a subwoofer
wherever you like. Normally place it in front of you.

If your speakers cannot be placed at the same distance from the
listening position
You can adjust the delay time of the center speaker and rear
speakers. For in-depth information about adjusting the delay time,
see “Setting the Delay Time” on page 18 and 19.
Note:
You can change the phase of subwoofer sounds by connecting the
speaker cords to the terminals inversely—the red cord to the black
terminal, and the black cord to the red terminal. You may get the more
effective bass sounds by changing the phase.
CAUTION:
•When attaching the satellite speakers on the wall, have them
attached to the wall by a qualified person.
DO NOT attach the satellite speakers on the wall by yourself to
avoid an unexpected damage of their falling from the wall, caused
by incorrect attachment or weakness in the wall.
•Care is required in selecting a location for attaching speakers to the
wall. Injury to personnel, or damage to equipment, may result if the
speakers are attached in a location which interferes with daily
activities.

EnglishThis system supports the progressive scanning system (480p*) as
well as the conventional interlaced scanning system (480i*).
If your TV equipped with component video jacks supports the
progressive video input, you can enjoy a high quality picture by
activating the progressive scanning mode.
•Refer also to the instruction manuals supplied with your TV.
•If your TV equipped with component video jacks does not support
the progressive video input, do not change the scanning mode to
the progressive scanning mode (P–SCAN MODE.)
* 480p and 480i indicate the number of scanning lines and scanning
format of a video signal.
•480p indicates 480 scanning lines with progressive format.
•480i indicates 480 scanning lines with interlaced format.
About scanning system
The conventional scanning method to display video signals on the
TV screen is called “Interlaced scanning.” With this method, only
half of the horizontal lines (called a “field”) are displayed at a time.
So two fields complete a single picture (frame);  i.e., the first field,
containing all the odd-numbered lines, is followed by the second
field, containing all the even-numbered lines.
On the other hand, the Progressive scanning system scans all
horizontal lines at a time, so you can double the number of scanning
lines displayed at a time, resulting in a flicker-free, high-density
picture.
To enjoy the progressive scanned picture, a monitor (or TV or
projector) connected to the system must support the progressive
video inputs.
Depending on the material source format, DVD video can be
classified into two types; film source and video source (note that
some DVD video contain both film source and video source). Film
sources are recorded as 24-frame-per-second data, while (NTSC)
video sources are recorded as 30-frame-per-second (60-field-per-
second interlaced).
When this system plays back a film source data, uninterlaced
progressive output signals are created using the original data. When
a video source is played back, the unit interleaves lines between the
interlaced lines to create the pseudo uninterlaced picture and outputs
as the progressive signals.
Changing the Scan Mode
You can select the scanning mode if your TV equipped with
component video jacks supports the progressive video input.
From the remote control ONLY:
1Press DVD.
You can change the scan mode only when DVD is
selected as the source and playback stops.
If a disc is no loaded, go to step 
3.
2 Press 7.
Playback stops.
3Press and hold PROGRESSIVE for a
while.
•Each time you press and hold the button, the scan
mode alternates between “I–SCAN MODE” and
“P–SCAN MODE”.
I (Interlace)–SCAN MODE
: Select this if your TV equipped with component video jacks does
not support the progressive video input (conventional TV).
P (Progressive)–SCAN MODE
: Select this if your TV equipped with component video jacks
supports the progressive video input.
Notes
•Some progressive TVs and High-Definition TVs are not fully
compatible with this system, resulting in the unnatural picture when
playing back a DVD in the progressive scanning mode.
In such a case, change the scanning mode to “I–SCAN MODE”
To check the compatibility of your TV, contact your local JVC
customer service center.
•All JVC progressive TVs and High-Definition TVs are fully
compatible with this system.
