tion 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 alter-
nating-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.

The power cord of the
product should be unplugged from the outlet
when left unused for long periods of time.
15. Outdoor Antenna Grounding.
If an out-
side 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
discharge unit, size of grounding conductors,
location of antenna-discharge unit, connec-
tion to grounding electrodes, and require-
ments for the grounding electrode. See
Figure 1.
16. 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 out-
let and disconnect the antenna or cable sys-
tem. This will prevent damage to the product
due to lightning and power-line surges.
17. 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.
18. Overloading.
Do not overload wall out-
lets, extension cords, or integral conve-
nience receptacles, as this can result in a
risk of fire or electric shock.
19. Object and Liquid Entry. 
Never push
objects of any kind into this product
through openings, as they may touch dan-
gerous voltage points or short-out parts that
could result in a fire or electric shock. Never
spill liquid of any kind on the product.
20. Servicing.

this product yourself, as opening or remov-
ing covers may expose you to dangerous
voltage or other hazards. Refer all servicing

The product has been dropped or damaged
in any way; or
The product exhibits a distinct change 
in performance – this indicates a need for
