9. Ventilation: Slots and openings in the cabinet are provided for ven-
tilation to ensure reliable operation of the product and to protect it
from overheating. These 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 in-
structions have been adhered to.
10. Power Sources: This product should be operated only from the type of
power source indicated on the rating 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.
11. Grounding or Polarization: This product may be equipped with a po-
larized alternating-current line plug that has one blade wider than
the other. This plug will only t into the power outlet in one direction.
This is a safety feature. If you are unable to insert the plug fully into
the outlet, try reversing the direction of the plug. If the plug should
still fail to t, contact an electrician to replace the obsolete outlet. Do
not defeat the safety purpose of the polarized plug.
12. 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, conve-
nience receptacles, and at the point which they exit from the product.
13. Protective Attachment Plug: The product may be equipped with an at-
tachment plug with overload protection. This is a safety feature. See
the operating instructions for replacement or directions to reset the
protective device. If replacement of the plug is required, be sure the
service technician has used a replacement plug that has the same over-
load protection as the original plug as specied by the manufacturer.
14. Outdoor Antenna Grounding: If an outside antenna is connected to
the product, be sure the antenna system is grounded so as to provide
some protection against voltage surges and built-up static charges.
Article 810 of the National Electrical Code, ANS/NFPA 70 provides in-
formation with regard to proper grounding of the mast and support-
ing 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 gure).
15. Lightning: For added protection for this product, unplug it from the
wall outlet and disconnect the antenna or cable system during a
lightning storm or when it is left unattended and unused for long pe-
riods of time. This will prevent damage to the product due to lightning
or power-line surges.
16. Power Lines: An outside antenna system should not be located in the
vicinity of overhead power lines or other electric light or power cir-
cuits, or where it can fall into such power lines or circuits. When in-
stalling an outside antenna system, extreme care should be taken to

www.naxa.com Page 9
keep from touching such power lines or circuits, as contact with them
might be fatal.
17. Overloading: Do not overload wall outlets, extension cords, or inte-
gral convenience receptacles as this can result in a risk of re or elec-
tric shock.
18. Object and Liquid Entry: Never push objects of any kind into this prod-
uct through openings as they may touch dangerous voltage points or
short-out parts that could result in a re or electric shock. Never spill
liquid of any kind on the product.
19. Servicing: Do not attempt to service this product yourself as open-
ing or removing covers may expose you to dangerous voltage or other
hazards. Refer all servicing to qualied service personnel.
20. Damage Requiring Service: Unplug this product from the wall outlet
and refer servicing to qualied service personnel under the follow-
ing conditions: a) when the power-supply or plug is damaged; b) if
liquid has been spilled or if 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
improper adjustment of other controls may result in damage and will
often require extensive work by a qualied technician to restore the
product to its normal operation; e) if the product has been dropped or
damaged in any way; f) when the product exhibits a distinct change in
performance—this indicates a need for service.
21. Replacement Parts: When replacement parts are required, be sure
that your service technician has used replacement parts specied
by the manufacturer or have the same characteristics as the original
part. Unauthorized substitutions may result in re, electric shock, or
other hazards.
22. Safety Check: Upon completion of any service or repairs to this
product,ask the service technician to perform safety checks to ensure
that the product is in proper operating condition.
23. Wall or Ceiling Mounting: The product should be mounted to a wall or
