IMPORTANT SAFETY INSTRUCTIONS
(Continued from previous page)
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 (U.S.A.), 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 dis-
charge unit, size of grounding co
nductors, location of
antenna-discharge unit, connection to grounding electrodes,
and requirements for the grounding electrode.
15. 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
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 and extension cords as this can
result in a risk of fire or electric shock.

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.
19. Servicing
Do not attempt to service this product yourself as opening
or removing covers may expose you to dangerous voltage or
other hazards. Refer all servicing to qualified service person-
