English
BE SURE to replace the fuse only with an identical approved type,
as originally fitted.
If nonetheless the mains plug is cut off ensure to remove the fuse
and dispose of the plug immediately, to avoid a possible shock
hazard by inadvertent connection to the mains supply.
If this product is not supplied fitted with a mains plug then follow the
instructions given below:
IMPORTANT:
DO NOT make any connection to the terminal which is marked with
the letter E or by the safety earth symbol or coloured green or greenand-yellow.
The wires in the mains lead on this product are coloured in
accordance with the following code:
Blue : Neutral

— SAFETY INSTRUCTIONS —
“SOME DOS AND DON’TS ON THE SAFE USE OF EQUIPMENT”
This equipment has been designed and manufactured to meet
international safety standards but, like any electrical equipment, care
must be taken if you are to obtain the best results and safety is to be
assured.
Do read the operating instructions before you attempt to use the
equipment.
Do ensure that all electrical connections (including the mains plug,
extension leads and interconnections between pieces of equipment)
are properly made and in accordance with the manufacturer’s
instructions. Switch off and withdraw the mains plug when making or
changing connections.
Do consult your dealer if you are ever in doubt about the installation,
operation or safety of your equipment.
Do be careful with glass panels or doors on equipment.
DON’T continue to operate the equipment if you are in any doubt about
it working normally, or if it is damaged in any way—switch off, withdraw
the mains plug and consult your dealer.
DON’T remove any fixed cover as this may expose dangerous voltages.
DON’T leave equipment switched on when it is unattended unless it is
specifically stated that it is designed for unattended operation or has a
standby mode.
Switch off using the switch on the equipment and make sure that your
family know how to do this.
Special arrangements may need to be made for infirm of handicapped
people.
DON’T use equipment such as personal stereos or radios so that you
are distracted from the requirements of traffic safety. It is illegal to watch
television whilst driving.

to ensure complete safety always fit the manufacturer’s approved stand
or legs with the fixings provided according to the instructions.
DON’T allow electrical equipment to be exposed to rain or moisture.
Thank you for purchasing a JVC speaker.
Before you begin using it, please read the instructions carefully
to be sure you get the best possible performance. If you have any
questions, consult your JVC dealer.
Warnings, Cautions and Others
To reduce the risk of electrical shocks, fire, etc.:
1. Do not remove screws, covers or cabinet.
2. Do not expose this appliance to rain or moisture.
Caution—POWER switch
This apparatus is provided with the POWER switch to minimize
power consumption for safe use. Therefore,
1. Before doing initial settings, complete all the connections
required, connect the mains plug into the wall outlet, then set
the POWER switch to ON [ ❙ ].
2. When not in use, set the POWER switch to OFF [ ‡ ].
This disconnects the mains line.
Cautions
• Do not block the ventilation openings or holes.
(If the ventilation openings or holes are blocked by a
newspaper or cloth, etc., the heat may not be able to get out.)
• Do not place any naked flame sources, such as lighted
candles, on the apparatus.
• When discarding batteries, environmental problems must be
considered and local rules or laws governing the disposal of
these batteries must be followed strictly.
• Do not expose this apparatus to rain, moisture, dripping or
splashing and that no objects filled with liquids, such as vases,
shall be placed on the apparatus.
Caution—Proper Ventilation
To avoid risk of electric shock and fire, and to prevent damage,
locate the apparatus as follows:
1 Front:
No obstructions and open spacing.
2 Sides/ Top/ Back:
No obstructions should be placed in the areas shown by the
dimensions below.
3 Bottom:
Place on the level surface. Maintain an adequate air path
for ventilation by placing on a stand with a height of 10 cm
or more.
Front viewSide view
Front
ABOVE ALL.
– NEVER let anyone, especially children, push anything into holes,
slots or any other opening in the case—this could result in a fatal
electrical shock.
– NEVER guess or take chances with electrical equipment of any kind—
it is better to be safe than sorry!

Precautions for installation
• To prevent deformation or discoloration of the
cabinet, do not install the unit where it is exposed
to direct sunlight or high humidity, and avoid
installation near air conditioning outlets.
• Speaker vibrations may cause howling. Place the
unit as far away from the player as possible.
• Take the occurrence of earthquakes or other
physical shocks into consideration when selecting
the installation place, and secure the unit
thoroughly.
• This unit is magnetically shielded to avoid color distortions on
TVs. However, if not installed properly, it may cause color
distortions. So, pay attention to the following when installing
the unit.
– When placing this unit near a TV set, turn off the TV’s main
power switch or unplug it before installing this unit.
Then wait at least 30 minutes before turning on the TV’s
main power switch again.
Some TVs may still be affected even though you have followed
the above. If this happens, move this unit away from the TV.
• Tuner reception may become noisy or hissing if this unit is
installed nearby the tuner. In this case, leave a more distance
between the tuner and this unit or use an outdoor antenna for
better tuner reception without interference from this unit.
Precautions for Daily Use
• To maintain the appearance of the unit
Wipe with a dry, soft cloth if the cabinet or control panel should
become dirty.
If very dirty, apply a small amount of water or neutral detergent
to the cloth and wipe clean. Then wipe with a dry cloth.
• To improve the sound field
If the speakers are facing a solid wall or glass
door, etc., it is recommended to furnish the wall
with materials that absorb sounds, for example by
hanging up thick curtains, to prevent reflections
and standing waves.
Warnings, Cautions and Others ........................................ 2
Before connecting this unit to your amplifier (or receiver), check

different from the ones actually used for your amplifier. The
illustrations are of the most used type.
First check whether your amplifier has a subwoofer output
jack.
It is usually named and printed as the “SUBWOOFER OUT” or
“SUBWOOFER.”
If you find it on your amplifier, follow Connecting MethodÅ.
If you cannot
find any
Before connecting this unit to the amplifier (or receiver),
observe the following carefully.

(HIGH-LEVEL) terminals on the rear of this unit at the
same time; otherwise, noise will be heard and may
damage the unit.
• DO NOT connect this unit to the REC OUT jacks of your
amplifier.
Connecting to the Amplifier
When connecting to your amplifier (or receiver), refer also the
manual supplied for your equipment.
Connecting Method Å
Connect an amplifier having a subwoofer output jack to the
LEFT/MONO jack of the INPUT 1 (LOW-LEVEL) terminal.
Preparation:
Use the supplied monaural
audio cord.
Next check whether your amplifier has line output jacks.
They are usually named and printed as “LINE OUT” or “LINE
OUTPUT.”
If you find them on your amplifier, follow Connecting Methodı.
