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.
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
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.
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.
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.
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.
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:
Manufacturing also creates sharp areas on
the unit; use thorough care in handling.
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.
＊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
15. Extended non-use
If the unit is likely to be unused for an
extended period, shut off power and
disconnect from power supply.
16. Volume Adjustment
If abnormal noise is produced during play at
high volume, reduce the volume level.
Distorted sound can cause overheating of
speakers and amplifier. Before switching

turn the power off and then back on again,
and check if this product is working normally.
17. Connecting TV/other audio equipment
When connecting a TV or other audio
equipment, always shut off power, read the
operating manual for each device and follow
the instructions for connection. Use only
designated cables.
Use of non-designated cables or extension
cables can cause heat production, burns,
and fire.
18. Antenna
An outdoor antenna should be located away
from power lines.
19. Maintenance.
Before undertaking maintenance disconnect
from power supply. Have the interior of the
unit cleaned approximately once a year by
qualified personnel. Accumulated dust inside
and long intervals without cleaning can
cause fire or malfunction. Before cleaning
this product make sure that the power is
turned off and the power cord is
disconnected from the wall outlet. Clean with
a soft cloth. If the product is particularly dirty,
moisten the cloth and wring out before use.
