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-

stalling 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.

17.  Overloading: Do not overload wall outlets, extension cords, or inte-

gral convenience receptacles as this can result in a risk of fire 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 fire 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 qualified service personnel.

20. Damage Requiring Service: Unplug this product from the wall outlet 

and refer servicing to qualified 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 qualified 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  specified 

by the manufacturer or have the same characteristics as the original 

part. Unauthorized substitutions may result in fire, 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.
