※Stereo mini/RCA plug cable(1.5m) is for connecting the amplifier with a playback
equipment which has RCA stereo output terminal such as CD player.
WARNING :
...........
To avoid the danger of suffocation, keep plastic bags out of the reach of
children.
＊This product is an amplifier system which has been designed using time domain theory
in order to maximise quality of speaker operation and performance.
《What is time domain theory?》
Time domain recreates the changes that occur in sound waves over time from the
moment of output until their disappearance. Its purpose is to reproduce those sound
waves that are as close as possible to the original recorded sound.
Time domain audio systems allow sound orientation and the nuances that are added by
recorded performers to be faithfully reproduced.

7. Where not to use unit
Do not use the unit in bathrooms, areas
exposed to rain or snow, on the shore,
near water or in humid conditions. Do not
place the unit in unstable locations, in
kitchens,near humidifiers, or in any location
with likely exposure to smoke or steam. Do
not place the unit in direct sunlight, near
heating equipment or close to open
flames. Fire, accident or malfunction may
result. Do not place the unit in locations
exposed to cold air or direct draft.
Condensation, leakage current or thermal
damage may result. Do not use the unit in
dusty or dirty locations. Decreased heat
ventilation can cause thermal damage
8. Unit heat
The bottom and sides of the unit can heat
up during use and should not be touched.
Burns may result. Only connect or
disconnect speaker cables after the power
supply has cooled down.
9. Moving the unit
When moving the unit, shut off power to all
connected equipment, and disconnect
power cords, connectoins cables, speaker
cables and other wires. Moving the unit
while cable are connected can cause
damage to cables, fire or electric shock.
The unit is heavy and care should be taken
when unpacking, moving or lifting.
Manufacturing also creates sharp areas on
the unit; use thorough care in handling.
＊Because the volume knob can be
separated from the amplifier, never hold
the volume knob when moving the
amplifier.
10. Power cord
Only use the power cord supplied and do
not bend, twist, modify it for repair, or pin it
under the unit. Heavy objects, heat or
tension may also damage the power cord
and cause fire or electric shock. When
disconnecting the power cord from an
outlet, do not pull the cord. Pulling on the
cord can damage it and cause fire or
electric shock. Do not touch the power
cord with wet hands. Do not place the
power cord near heating equipment and
do not use the unit. If the plug fits loosely in
an electric outlet or the plug or cord is hot.
If the cord is damaged replace it as
continued use may result in fire or electric
shock.
11. Unit plug
Insert the plug into an outlet all the may to
its base. Incomplete insertion can cause
heat production, and dust build-up can
cause fire. Contact with the prongs of the
plug can also cause electric shock. Do not
connect the unit to an outlet where the
connection is loose even when the plug is
inserted all the way to its base. Do not use
the unit if the plug is hot. Heat production
can cause fire.
If dust or metal accumulates on or near the
prongs of the plug, wipe the plug with a
dry cloth after disconnection. Continued
use may cause fire or electric shock.
12. Danger signs
If you notice a strange noise, smoke,
unusual odour or other abnormal
condition, shut off the unit, disconnect the
power cord from the outlet and have the
unit inspected. Continued use may result in
fire or electric shock.
13. Electric storms
During electrical storms disconnect the unit
and avoid contact with the antenna and
power cord. Lightning can cause fire,
electric shock and malfunction.
14. Internal temperature rise
To avoid internal temperature rise when
installing the unit, leave space between the
unit and walls or other equipments. When
installed in a rack or similar fixture, leave a
10cm (4") or larger gap on top and at sides
since internal temperature rise can result in
fire. The unit is provided with ventilation
holes to prevent internal temperature rise.
Blockage of these holes decreases
ventilation and can result in fire. Note the
following:
＊Do not place the unit in a poorly
ventilated area
＊Do not place the unit on carpeting or on
bedding
＊Do not obstruct the ventilation holes
＊Do not tilt the unit or turn upside down
