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.

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

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

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.

repairs to this appliance, ask the service technician to
perform safety checks to determine that the appliance
is in proper operationg condition.
24. Do not mount this appliance to a wall or ceiling. Refer to
the installation section for proper placement.
