IMPORTANT SAFETY INSTRUCTIONS
READ FIRST!
Important Safety Precautions!
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION: To reduce the risk of electric shock,
do not remove cover (or back).
No user-serviceable parts inside.
Refer servicing to qualified service personnel.
CAUTION: To prevent electric shock,
do not use this (polarized) plug with
an extension cord, receptacle or other outlet
unless the blades can be fully inserted to
prevent blade exposure.
The lightning flash with arrowhead symbol,
within an equilateral triangle, is intended to
alert the user to the presence of uninsulated
"dangerous voltage" within the product's
enclosure that may be of sufficient magnitude to constitute
a risk of electric shock to persons.
The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near
water.
6. Clean only with a dry cloth.
7. Do not block any ventilation
openings. Install in accordance with
the manufacturer's instructions.
8. Do not install near any heat
sources such as radiators, heat
registers, stoves or other apparatus
(including amplifiers) that produce
heat.
9. 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 ground-
ing-type plug has two blades and a
third grounding prong. The wide
blade or the third prong are
provided for your safety. If the
provided plug does not fit into your
outlet, consult an electrician for
replacement of the obsolete outlet.
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, tri-
pod, bracket or table specified by the
manufacturer or sold with
the apparatus. When a cart
is used, use caution when
moving the cart/apparatus combina-
tion to avoid injury from tip-over.
13. Unplug this apparatus during light-
ning 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 dam-
aged, liquid has been spilled or
objects have fallen into the appara-
tus, 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 require-
ments for the grounding electrode.
See Figure A.

18. An outside antenna system should
not be located in the vicinity of over-
head power lines or other electric
light or power circuits, or where it
can fall into such power lines or cir-
cuits. 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 conven-
ience 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. 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.
22. When replacement parts are
required, be sure the service tech-
nician has used replacement parts
specified by the manufacturer or that
have the same characteristics as the
original part. Unauthorized substitu-
tions may result in fire, electric shock
or other hazards.
23. Upon completion of any service or
repairs to this product, ask the serv-
ice technician to perform safety
checks to determine that the product
is in proper operating condition.
24. The product should be mounted
to a wall or ceiling only as recom-
mended by the manufacturer.
