ANTENNA
Outdoor Antenna Grounding- If an outdoor antenna is
installed, follow the precautions below.
An outdoor antenna system should not be located in the
vicinity of overhead power lines or other electric light or
power circuits, or where it can come in contact with such
power lines or circuits.
WHEN INSTALLING AN OUTDOOR ANTENNA SYSTEM,
EXTREME CARE SHOULD BE TAKEN TO KEEP FROM
CONTACTING SUCH POWER LINES OR CIRCUITS AS
CONTACT WITH THEM IS ALMOST INVARIABLY FATAL
Be sure the antenna system is grounded so as to provide
some protection against voltage surges and built-up static
charges. Section 810 of the National Electrical Code in
USA and Section 54 of the Canadian Electrical
Code(ANSl/NFPA 70) in Canada provides information with
respect to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna dis-
charge unit, size of grounding conductors, location of
antenna discharge unit, connection to grounding elec-
trodes, and requirements for the grounding electrode.
Replacement Parts - When replacement parts are required, be sure the service technician has used replacement parts
specified by the manufacturer or h a v e t h e s a m e c h a r a c t e r i s t i c s a s t h e o r i g i n a l parts. Unauthorized substitutions may
result in fire, electric shock, or other hazards.
Safety Check - Upon completion of any service or repairs to the TV set, ask the service technician to perform routine safety
checks to determine that the TV set is in proper operating condition.
Disposal - When the TV set reaches the end of its useful life, improper disposal could result in a picture tube implosion.
Ask a qualified service technician to dispose of the TV set.
