Do not defeat the safety purpose of the

polarized or grounding-type plug. A polarized plug
has two blades with one wider than the other. A

grounding prong. The wide blade or the third
prong is provided for your safety. If the provided
plug does not fit into your outlet, consult an

10.

Protect the power cord from being walked on

or pinched, particularly at plugs, convenience
receptacles and the point where they exit from the
apparatus.

11.

Only use attachments/accessories specified by

the manufacturer.

12.

Use only with the cart, stand, tripod, bracket or

table specified by the manufacturer or sold with
the apparatus. When a cart is used, use caution
when moving the cart/apparatus
combination to avoid injury from
tip-over.

13.

Unplug this apparatus during

lightning storms or when unused for
long periods of time.

14.

Refer all servicing to qualified service

personnel. Servicing is required when the
apparatus has been damaged in any way, such 
as power-supply cord or plug is damaged, liquid
has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain
or moisture, does not operate normally, or has
been dropped.

15.

Do not use attachments not recommended by

the product manufacturer, as they may cause
hazards.

16.

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.

17.

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.

18.

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.

19.

Do not overload wall outlets, extension cords,

or integral convenience receptacles, as this can
result in a risk of fire or electric shock.

20.

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.

21.

The apparatus shall not be exposed to dripping

or splashing, and no objects filled with liquids,
such as vases, shall be placed on the apparatus.

22.

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.

23.

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.

24.

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.

25.

The product should be mounted to a wall or

ceiling only as recommended by the manufacturer.
