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

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 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.

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. Nonuse Periods.

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 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
discharge unit, size of grounding conductors,
location of antenna-discharge unit,
connection to grounding electrodes, and
requirements for the grounding electrode.
See Figure A.

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 outlet
and disconnect the antenna or cable system.
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

outlets, extension cords, or integral
convenience 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 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.

20. 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 personnel.

21. Damage Requiring Service.

Unplug this

product from the wall outlet and refer ser-
vicing to qualified service personnel under 
the following conditions:
a. The power-supply cord or the plug has
been damaged; or
b. Objects have fallen onto, or liquid has
been spilled into, the product; or
c. The product has been exposed to rain or
water; or
d. The product does not operate normally
when following the operating instructions.
Adjust only those controls that are covered
by the operating instructions, as an improper
adjustment of other controls may result in
damage and will often require extensive
work by a qualified technician to restore the
product to its normal operation; or
e. The product has been dropped or
damaged in any way; or
f. The product exhibits a distinct change 
in performance – this indicates a need for
service.

22. Replacement Parts.

When replacement

parts are required, be sure the service
technician has used replacement parts
specified by the manufacturer or that have
the same characteristics as the original part.
Unauthorized substitutions may result in fire,
electric shock or other hazards.

23. Safety Check.

Upon completion of any 

service or repairs to this product, ask the 
service technician to perform safety checks 
to determine that the product is in proper
operating condition.

24. Wall or Ceiling Mounting.

The product

should be mounted to a wall or ceiling only
as recommended by the manufacturer.

25. Heat.

The product should be situated

away from heat sources such as radiators,
heat registers, stoves, or other products
(including amplifiers) that produce heat.
