11. Grounding
This applies to video products
equipped with a
grounding-type plug, a plug
having a third (grounding) pin. This plug only fits into a
grounding-type power outlet. This is a safety feature. 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.
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,
p a y i n g p a r t i c u l a r a t t e n t i o n t o c o r d s a t p l u g s ,
convenience receptacles, and the point where they exit
from the video product.
13. Outdoor Cable Grounding
If an outside cable
system is connected to the video product, be sure the
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,
70-1984, provides information with respect
to proper 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.
14. Lightning
For added protection for this video
product when it is not used for long periods of time,
disconnect it from its power source and from the cable
system. This prevents damage to the video product due
to lightning and power-line surges.
15. Power Lines
An outside cable 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 cable system, extreme care should be taken to
keep from touching such power lines or circuits as
contact with them might be fatal.
16. Overloading
Do not overload wall outlets and
extension cords as this can result in a risk of fire or
electric shock.
17. Object and Liquid Entry
Never push objects of
any kind into this video 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 video product.
16. Servicing
Do not attempt to service this video
product yourself as opening or removing covers may
expose you to dangerous voltage or other hazards.
