23) 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 (U.S.A.), ANSI/ NFPA70 provides information with
regard to proper grounding of the lead-in wire to an antenna
discharge unit, size of grounding conductors, location of
antenna-dis-charge unit, connection to grounding electrodes,
and requirments for the grounding electrode.
24) Power Lines
An outside antenna system should not be located in the vicin-
ity of overhead power lines or other electric light or power cir-
cuits, 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.
25) Overloading
Do not overload wall outlets and extension cords as this can
result in a risk of fire or electric shock.

17) Attachments
Do not use attachments not recommended by the product
manufacturer as they may cause hazards.
18) 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 provid-
ed or the manufacturer s instructions have been adheredto.
19) 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 oper-
ate from battery power, or other sources, refer to the operating
instructions.
20) Power-Cord Polarization
This product is equipped with a three-wire grounding type
plug, a plug having a third (grounding) pin. This plug will only
fit into the grounding-type power outlet. This is a safety fea-
ture. If you are unable to insert the plug into the outlet, contact
your electrician to replace your obsolete outlet. Do not
defeat the safety purpose of the grounding-type plug.
21) 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.
22) Lightning
For added protection for this product (receiver) during a
lightning storm, or when it is left unattended and unused for
long periods of time, unplug it from the wall outlet and discon-
nect the antenna or cable system. This will prevent damage
to the product due to lightning and power-line surges.
