14. Outdoor Antenna Grounding – If an out-

side antenna or cable system is connected

to the appliance, be sure the antenna or

cable system is grounded so as to provide

some protection against voltage surges

and built-up static charges. Article 810 of

the National Electrical Code, ANSI/NFPA

70, provides information with regard to

proper grounding of the mast and sup-

porting 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 1.

15. Lightning – For added protection for the

appliance 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 appliance due to lightning and

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 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.

17. Overloading – Do not overload wall out-

lets, extension cords, or integral conve-

nience receptacles as this can result in a

risk of ﬁre or electric shock.

18. Object and Liquid Entry – Never push

objects of any kind into the appliance

through openings as they may touch dan-

gerous voltage points or short-out parts

that could result in a ﬁre or electric shock.

Never spill liquid of any kind on the appli-

ance.

19. Servicing – Do not attempt to service the

appliance yourself as opening or remov-

ing covers may expose you to dangerous

voltage or other hazards. Refer all servic-

ing to qualiﬁed service personnel.

20. Damage Requiring Service – Unplug the

appliance form 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, or objects

have fallen into the appliance,

C. If the appliance has been exposed to

rain or water,

D. If the appliance does not operate nor-

mally by following the operating

instructions. Adjust only those con-

trols 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

appliance to its normal operation,

E. If the appliance has been dropped or

damaged in any way, and

F. When the appliance exhibits a distinct

change in performance – this indicates

a need for service.

21. Replacement Parts – When replacement

parts are required, be sure the 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 the appliance, ask the

service technician to perform safety

checks to determine that the appliance is

in proper operation condition.

23. Wall or Ceiling Mounting – The appliance

should be mounted to a wall or ceiling only

as recommended by the manufacturer.

24. Heat – The appliance should be situated

away from heat sources such as radiators,

heat registers, stoves, or other appliances

(including ampliﬁers) that produce heat.
