1+_.Outdoor Antenna grounding-lf an outside antenna or

cable system is connected to the TV/VCR, 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 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-dis-

charge unit, connection to grounding electrodes, and re-

quirements for the grounding electrode. (Fig. A)

14. Lightning-For added protection for this TVIVCR re-

ceiver during a lightning storm, or when it is left unat-

tended 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 TV/VCR 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.

Overloading-Do not overload wall outlets andextension

cords as this can result in a risk of fire or electric shock.

18.

Object and Liquid Entry-Never push objects of any kind

into this TV/VCR 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 TV/VCR.

Servicing-Do not attempt to service this TV/VCR your-

self as opening or removing covers may expose you to

dangerous voltage or other hazards. Refer all servicing to

qualified service personnel.
