IMPORTANT SAFEGUARDS
6. Temperature The appliance may not function
properly if used at extremely low, or freezing
temperatures. The ideal ambient temperature is
above +5°C (41°F).
7. Heat The appliance should be situated away from
heat sources such as radiators, heat registers, stoves,
or other appliances (including amplifiers) that produce
heat.
8. Electric shock Care should be taken so that objects
do not fall and liquid is not spilled into the enclosure
through openings. If a metal objects, such as a hair
pin or a needle, comes into contact with the inside of
this appliance, a dangerous electric shock may result.
For families with children, never permit children to
put anything, especially metal, inside this appliance.
9. Enclosure removal Never remove the enclosure.
If the internal parts are touched accidentally, a serious
electric shock might occur.
10.Magnetic fields Keep the appliance away from
sources of magnetic fields such as TV sets, speaker
systems, radios, motorized toys or magnetized
objects.
11.Cleaning Unplug this appliance from the wall
outlet before cleaning. Do not use volatile solvents
such as alcohol, paint thinner, gasoline, or benzine,
etc. to clean the cabinet. Use a clean dry cloth.
12.Accessories Do not place this appliance on an unstable
cart, stand, tripod, bracket, or table. The appliance may fall,
causing serious injury to a child or adult, and serious
damage to the appliance. Use only with a cart, stand,
tripod, bracket, or table recommended by the manufacturer,
or sold with the appliance. Any mounting of the appliance
should follow the manufacturer's instructions, and should
use a mounting accessory recommended by the
manufacturer. An appliance and cart combination should
be moved with care. Quick stops, excessive force, and
uneven surfaces may cause the appliance and cart
combination to overturn.
Please read all of the safety and operating instructions
before operating this appliance. Adhere to all warnings on
the appliance and in the instruction manual. Follow all the
safety and operating instructions.
These safety and
operating instructions should be retained for future
reference.
1. Power sources The appliance should be connected to
a power supply only of the type described in the instruction
manual or as marked on the appliance. If you are not sure
of the type of power supply to your home, consult your
appliance dealer or local power company. For appliances
intended to operate from battery power, or other sources,
refer to the instruction manual.
2. Power-cord protection Power-supply cords should
be routed so that they are not likely to be walked on
or pinched by items placed upon or against them,
pay particular attention to cords at plugs, convenience
receptacles, and the point where they exit from the
appliance.
3. CAUTION Polarization This appliance may be
equipped with a polarized alternating-current line plug (a
plug having one blade wider than the other). This plug will
fit into the power outlet only one way. This is a safety
feature. If you are unable to insert the plug fully into the
outlet, try reversing the plug. If the plug should still fail to
fit, contact your electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the polarized plug.
4. Ventilation Slots and openings in the cabinet are
provided for ventilation and to ensure reliable operation of
the appliance and to protect it from overheating, and these
openings must not be blocked or covered. The appliance
should be situated so that its location or position does not
interfere with its proper ventilation.
To maintain good ventilation, do not put records or a table-
cloth on the appliance. Place the appliance at least 10 cm
away from the walls.
Do not use the appliance on a bed, sofa, rug or similar
surface that may block the ventilation openings.
This
appliance should not be placed in a built-in installation such
as a bookcase or rack unless proper ventilation is provided
or the manufacturer's instructions have been adhered to.
5. Water and moisture The appliance should not be
used near water - for example, near a bathtub,
washbowl, kitchen sink, laundry tub, in a wet
basement, or near a swimming pool, etc.
Never pull or stretch
the cord.

13.Lightning For added protection for this appliance during
a lightning storm, or when it is left unattended and unused
for long periods of time, unplug it from the wall outlet and
disconnect the antenna or cable system. This will prevent
damage to the appliance due to lightning and power-line
surges.
14.Abnormal smell If an abnormal smell or smoke is
detected, immediately turn the power OFF and unplug
the appliance from the wall outlet. Contact your dealer or
nearest service center.
15.Damage requiring service The appliance should
be serviced by qualified service personnel when:
A. The power-supply cord or the plug has been
damaged.
B. Objects have fallen, or liquid has been spilled into
the appliance.
C. The appliance has been exposed to rain or water.
D. The appliance does not appear to operate normally
by following the instruction manual. Adjust only those
controls that are covered by the instruction manual as an
improper adjustment of other controls may result in damage
and will often require extensive work by a qualified
technician to restore the appliance to its normal operation.
E. The appliance has been dropped, or the enclosure
damaged.
F. The appliance exhibits a marked change in performance.
16.Servicing The user should not attempt to service
the appliance beyond that described in the instruction
manual. All other servicing should be referred to
qualified service personnel.
17.Outdoor antenna grounding If an outside antenna
is connected to the appliance, be sure the antenna
system is grounded so as to provide some protection
against voltage surges and built up static charges.
Article 810 of the National Electrical Code
ANSI/
NFPA 70, provides information with respect to proper
grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge
unit, size of grounding conductors, location of antenna
discharge unit, connection to grounding electrodes,
and requirements for the grounding electrode. See
Figure.
18.Power lines An outside antenna system should not be
located in the vicinity of overhead power lines or other
electric light or power circuits, or where it can fall into such
power lines or circuits. When installing an outside antenna
system, extreme care should be taken to keep from
touching such power lines or circuits as contact with them
might be fatal.
19.AC outlets Do not connect other audio equipment
with a power consumption larger than that specified
to the AC outlet on the rear panel. Never connect
other electrical appliances, such as an iron or toaster,
to it to prevent fire or electric shock.
20. Overloading Do not overload wall outlets, extension
cords, or integral convenience receptacles as this can
result in a risk of fire or electric shock.
21. Attachment Do not use attachments not recommended
by the appliance manufacturer as they may cause hazards.
22. Replacement parts When replacement parts are required,
be sure the service technician has used replacement parts
specified by the manufacturer or have the same
characteristics as the original parts. Unauthorized
substitutions may result in fire, electric shock, or other
hazards.
23. Safety check Upon completion of any service or repairs
to this appliance, ask the service technician to perform
safety checks to determine that the appliance is in proper
operating condition.
Notes:
1. Item 3 is not required except for grounded or polarized equipment.
2. Item 17 and 18 are not required except for units provided with
antenna terminals.
3. Item 17 complies with UL in the U.S.A.
