ENGLISH
10) Ventilation — Slots and openings in the
cabinet are provided for ventilation and to
ensure reliable operation of the product and to
protect it from overheating, and these
openings must not be blocked or covered. The
openings should never be blocked by placing
the product on a bed, sofa, rug, or other
similar surface. This product 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.
11) Power Sources — This product 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 product dealer or local
power company. For products intended to
operate from battery power, or other sources,
refer to the operating instructions.
12) Grounding or Polarization — This
product 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.
13) 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.
14) Outdoor Antenna Grounding — If an
outside antenna or cable system is connected
to the product, be sure the antenna or cable
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 regard to proper grounding
of the mast and supporting structure,
grounding of the lead-in wire to an antenna
3
discharge unit, size of grounding conductors,
location of antenna-discharge unit, connection
to grounding electrodes, and requirements for
the grounding electrode.
Note to CATV system installer:
This reminder is provided to call the CATV
system installer‘s attention to Section 820-40
of the NEC which 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.
15) Lightning — For added protection for this
product 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 product due to
lightning and power-line surges.
16) 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.
17) Overloading — Do not overload wall
outlets, extension cords, or integral
convenience receptacles as this can result in
risk of fire or electric shock.
18) Object and Liquid Entry — Never push
objects of any kind into this product through
openings as they may touch dangerous
voltage points or short-out parts that could
result in a fire or electric shock. Never spill
liquid of any kind on the product.
