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 fit 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 fit, 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, con-
venience receptacles, and at the point which they exit 
from the product.

13.  Protective  Attachment  Plug:  The  product  may  be 

equipped with an attachment plug with overload 
protection. This is a safety feature. See the operat-
ing instructions for replacement or directions to re-
set the protective device. If replacement of the plug is 
required, be sure the service technician has used a replace-
ment plug that has the same overload protection as the original plug as 
specified 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 figure).

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-
