n SAFETY PRECAUTIONS
RISK OF ELECTRIC SHOCK
DO NOT OPEN
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE
COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
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.
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT
EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.
1. Read Instructions – All the safety and operating instructions should be read
before the product is operated.
2. Retain Instructions – The safety and operating instructions should be
retained for future reference.
3. Heed Warnings – All warnings on the product and in the operating
instructions should be adhered to.
4. Follow Instructions – All operating and use instructions should be followed.
5. Cleaning – Unplug this product from the wall outlet before cleaning. Do not

6. Attachments – Do not use attachments not recommended by the product
manufacturer as they may cause hazards.
7. Water and Moisture – Do not use this product near water – for example,
near a bath tub, wash bowl, kitchen sink, or laundry tub; in a wet basement;
or near a swimming pool; and the like.
8. Accessories – Do not place this product on an unstable cart, stand, tripod,
bracket, or table. The product may fall, causing serious injury to a child or
adult, and serious damage to the product. Use only with a cart, stand,
tripod, bracket, or table recommended by the manufacturer, or sold with the
product. Any mounting of the product should
follow the manufacturer’s instructions, and should
use a mounting accessory recommended by the
9. A product and cart combination should be moved
with care. Quick stops, excessive force, and
uneven surfaces may cause the product and cart
combination to overturn.
10. Ventilation – Slots and openings in the 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 placing the product on a bed, sofa,
rug, or other similar surface. This product should 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
alternating-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.
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
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 servicing to qualiﬁed service personnel under the following
a) When the power-supply cord or plug is damaged,
b) If liquid has been spilled, or objects have fallen into the product,
c) If the product has been exposed to rain or water,
d) If the product does not operate normally by 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,
e) If the product has been dropped or damaged in any way, and
f) When 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 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
