Section 810 of the National
Electrical Code, ANSI/NFPA No.
70-1984, 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 connectors, location of
antenna-discharge unit, connec-
tion to grounding electrodes and
requirements for the grounding
electrode. See illustration at right.
15. Non-use Periods - The power cord of the appliance should be unplugged
from the outlet when left unused for a long period of time.
16. Object and Liquid Entry - Care should be taken so that objects do not fall
and liquids are not spilled into the enclosure through openings.
17. Damage Requiring Service - The appliance should be serviced by qualified
service personnel when:
A. The power supply cord or the plug has been damaged; or
B. Objects have fallen or liquid has been spilled into the appliance; or
C. The appliance has been exposed to rain; or
D. The appliance does not appear to operate normally or exhibits a marked
change in performance; or
E. The appliance has been dropped or the enclosure has been damaged.
18. Servicing - The user should not attempt to service the appliance beyond
that described in the operating instructions. All other servicing should be
referred to qualified service personnel.
19. Overloading - Do not overload wall outlets and extension cords as this can
result in a risk of fire or electric shock.
20. Replacement Parts - When replacement parts are required, be sure the
service technician uses replacement parts specified by the manufacturer or
which have the same characteristics as the original part. Unauthorized sub-
stitutions 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. Grounding or Polarization - Your TV operates on 120V/60Hz and has 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 safe-
ty feature. If you are unable to insert the plug fully into the outlet, reverse the
plug. If the plug still does not fit, ask your electrician to replace your obsolete
outlet. Do not defeat the safety purpose of the polarized plug.
23. Lightning - For added protection of this product during a lightning storm, or
when it is left unattended and unused for a long 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 line surges.
24. Attachments - Do not use attachments not recommended by the video
product manufacturer. They may be hazardous.
Note to the Cable TV system installer: This reminder is provided to call the Cable
TV system installer's attention to Article 820-40 of the NEC that provides guide-
lines for proper grounding and, in particular, specifies that the cable ground shall
be connected to the grounding system of the building, as close to the point of
cable entry as practical.
