some specific reason, such as the possibility of the loss of an 
authorization code for a CATV converter, is not intended to be 
unplugged by the user for cleaning or any other purpose, may exclude

8A. 

9. Ventilation — Slots and openings in the cabinet are provided for 
ventilation, to ensure reliable operation of the video product, and to 
protect it from overheating. These openings must not be blocked or 
covered. The openings should never be blocked by placing the video 
product on a bed, sofa, rug, 
or other similar surface. This video product should never be placed near 
or over a radiator or heat register. This video 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.
10. Power Sources — This video 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 appliance 
supplier or local power company. For video products intended to 
operate from battery power, or other sources, refer to the operating 
instructions.
11. 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.
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, 
convenience receptacles, 
and the point where they exit from the appliance.
13. Outdoor Antenna Grounding — If an outside antenna or cable 
system is connected to the video product, be sure the antenna or cable 
system is grounded so as to provide some protection against voltage 
surges and built-up static charges.
Section 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 Fig.A.

14. 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 surges.
15. 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.
16. Overloading — Do not overload wall outlets and extension cords as 
this can result in a risk of fire or electric shock.
17. 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.
18. 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.
19. Damage Requiring Service — Unplug this product from the wall 
outlet and refer servicing to qualified service personnel under the 
following conditions:
a. When the power-supply cord or plug is damaged.
b. If liquid has been spilled on, 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 the cabinet has been damaged.
f. When the product exhibits a distinct change in performance - this 
indicates a need for service.
20. Replacement Parts — When replacement parts are required, be sure 
the service technician has used replacement parts specified by the 
manufacturer or which have the same characteristics as the original part. 
Unauthorized substitutions may result in fire, electric shock or other 
hazards.
21. 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.
22. Carts and Stands — The appliance should be used only with a cart or 
stand that is recommended by the manufacturer.
