13.Outdoor Antenna grounding-If an outside antenna or

cable system is connected to the unit, be sure the antenna

or cable system is grounded so as to provide some protec-

tion against voltage surges and built-up static charges.

Article 810 of the National Electrical Code, ANSI/NFPA

No. 70, provides information with respect 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. (Fig. A)

14.Lightning-For added protection for this unit receiver dur-

ing 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 unit due to lightning and power-line

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 unit through openings as they may touch danger-

ous voltage points or short out parts that could result in a

fire or electric shock. Never spill liquid of any kind on the

unit.

18.Servicing-Do not attempt to service this unit 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 unit 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 or frayed.

b. If liquid has been spilled, or objects have fallen into the

unit.

c. If the unit has been exposed to rain or water.

d. If the unit does not operate normally by following the oper-

ating instructions. Adjust only those controls that are cov-

ered 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 unit to its normal operation.

e. If the unit has been dropped or damaged in any way.

f. When the unit 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 that have the same character-

istics as the original part. Unauthorized substitutions may

result in fire, electric shock, injury to persons or other haz-

ards.

21.Safety Check-Upon completion of any service or repairs to

this unit, ask the service technician to perform routine safe-

ty checks to determine that the unit is in proper operating

condition.

22.Heat-This unit product should be situated away from heat

sources such as radiators, heat registers, stoves, or other

products (including amplifiers) that produce heat.
