WARNING
TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK, DO NOT EXPOSE THIS
APPLIANCE TO RAIN OR MOISTURE.
Portable cart - 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.
Ventilation - The unit should be situated with adequate space
around it so that proper heat ventilation is assured.
Allow 10 cm
clearance from the rear and the top of the unit, and 5 cm from
the each side.
Slots and openings in the cabinet and the back or bottom are
provided for ventilation, and to ensure reliable operation of the
unit and to protect it from overheating, these openings must not
be blocked or covered.
The openings should never be blocked
by placing the unit on a bed, sofa, rug or other similar surface.
This unit should not be placed in a built-in installation such as a
bookcase unless proper ventilation is provided.
Object and Liquid Entry - Never push objects of any kind into
this unit through the cabinet slots as they may touch dangerous
voltage points or short-circuit parts that could result in a fire or
electric shock. Never spill liquid of any kind on the unit.
Electric Power
Power Sources - This unit should be operated only from the
type of power source indicated on the marking label. If you are
not sure of the type of power supply to your home, consult your
appliance dealer or local power company
. To operate unit on
battery power , or other sources, refer to the operating instructions.
Grounding or Polarization - This unit is provided 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.
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, paying particular attention to cords
at plugs, convenience receptacles, and the point where they exit
from the product.
Overloading - Do not overload wall outlets, extension cords,
integral convenience receptacles as this can result in a risk of
fire or electric shock.
Outdoor Antenna
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.
Outdoor Antenna Grounding - If an outside antenna or cable
system is connected to the unit, be sure the antenna or cable
system is grounded so as to provide some protection against
voltage surges and built-up static charges. Section 810 of the
National Electrical Code, ANSI/NFPA No.70, provides information
with regard 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 the figure.
RISK OF ELECTRIC SHOCK
DO NOT OPEN
"CAUTION: TO REDUCE THE RISK OF
ELECTRIC SHOCK,
DO NOT REMOVE COVER (OR BACK).
NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED
SERVICE PERSONNEL."
