READ FIRST!
Important Safety Precautions!
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 appara-
tus (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 grounding-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, par-
ticularly 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 dam-
aged, liquid has been spilled or
objects have fallen into the appa-
ratus, 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 oper-
ated 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 prod-
ucts intended to operate from bat-
tery power, or other sources, refer
to the operating instructions.
17. If an outside antenna or cable
system is connected to the prod-
uct, be sure the antenna or cable
system is grounded so as to pro-
vide some protection against volt-
age 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 requirements for the grounding
electrode. See Figure A.
18. An outside antenna system
should not be located in the vicin-
ity of overhead power lines or
other electric light or power cir-
cuits, or where it can fall into such
power lines or circuits. When
installing an outside antenna sys-
tem, 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 con-
venience 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 volt-
age 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 haz-
ards. Refer all servicing to quali-
fied 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
substitutions may result in fire,
electric shock or other hazards.
23. 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. The product should be mounted
to a wall or ceiling only as recom-
mended by the manufacturer.

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.
