Skyworth SLTV-1551A-1 - Manual (Page 3)

11.POLARIZATION - This unit is 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 still fails to fit, contact your electrician to
replace your obsolete outlet. Do not defeat the
safety purpose of the polarized plug.
12.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 appliance.
13.LIGHTNING - To protect your unit 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 unit
due to lightning and power line surges.
14. 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.
15.OVERLOADING - Do not overload wall outlets
and extension cords as this can result in a risk of
fire or electric shock.
16.OBJECT AND LIQUID ENTRY - Do not push
objects through any openings in this unit as they
may touch dangerous voltage points or short out
parts that could result in fire or electric shock.
Never spill or spray any type of liquid into the unit.
17.OUTDOOR ANTENNA GROUNDING - If a n
outside antenna or cable system is connected to
the unit, be sure the antenna or cable system is
grounded to provide some protection against
voltage surges and built-up static charges.
Section 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,
c o n n e c t i o n t o g r o u n d i n g e l e c t r o d e s , a n d
requirements for the grounding electrode.
18.SERVICING - Do not attempt to service this
unit yourself as opening or removing covers may
expose you to dangerous voltage or other
hazards. Refer all servicing to qualified service
personnel. 19.DAMAGE REQUIRING SERVICE - Unplug this
unit from the wall outlet and refer servicing to
qualified service personnel under the following
conditions:
A. When the power-supply cord or plug is
damaged.
B. If liquid has been spilled, or objects have fallen
into the unit.
C. If the unit has been exposed to rain or water.
D. If the unit does not operate normally by
following the operating instructions. Adjust
only those controls that are covered by the
operating instructions, as an improper
adjustment of other controls may result in
damage and will often require extensive work
by a qualified technician to restore the unit to
Its normal operation.
E. If the unit has been dropped or the cabinet has
been damaged.
F. When the unit exhibits a distinct change in
performance, this indicates a need for service.
20.REPLACEMENT PARTS- When replacement
parts are required, be sure the service technician
u s e s r e p l a c e m e n t p a r t s s p e c i f i e d b y t h e
manufacturer or those that have the same
characteristics as the original part. Unauthorized
substitutions may result in fire, electric shock or
other hazards.
21.SAFETY CHECK - Upon completion of any
service or repairs to this unit, ask the service
technician to perform safety checks to determine
that the unit is in proper operating condition.
22.HEAT - The product should be situated away
from heat sources such as radiators, heat
registers, stoves, or other products(including
amplifiers) that produce heat.
23.NOTE TO CATV SYSTEM INSTALLER - This
reminder is provided to call the CATV system
installer s attention to Article 820-40 of the NEC
that provides guidelines for proper grounding and,
In particular, specifies that the cable ground shall
be connected to the grounding system of the
building, as close to the point of cable entry as
practical.
